The SCOPE of the INVENTION

The present invention relates to methods and systems for drug delivery by electrophoresis. More specifically, the present invention relates to new and effective methods and systems for drug delivery by electrophoresis for anestesiologia tissue of the ear.

BACKGROUND of INVENTION

Electrophoresis is a method of drug delivery through biological membrane, such as skin or when performing certain surgical operations on the ear, the eardrum (BP). Under the action of low-level electric current charged on the same solution containing the medicinal substance, when electrophoresis is the repulsion of ions of medicinal substances and their transport through the skin or other membrane. Earlier in surgery of the ear, attempts were made use of electrophoresis for anestesiologia (or "call numbness") BP before the introduction through her tube for the treatment of chronic inflammation of the middle ear. In the line is the use of electrophoresis BP drug solution is injected into the ear canal and with the electrode through the solution to an electric current, thus, transported anaesthetic substance through the PSU. The possibility of application of devices and systems electrophoresis prior art is limited, as they are not suitable for every patient. Devices of the prior art, generally not capable of tightly holding the medicinal solution in the ear canal, therefore, during the procedure of electrophoresis, the patient will need to bounce back and tilted his head. When using currently known methods of electrophoresis, the patient should almost motionless to be in a half upright position with tilted his head for 5-15 minutes until the electrophoresis procedure does not provide adequate anesthesia BP, which can be particularly difficult for children. In addition, the use of known systems allows you to perform the anesthesia only one ear at a time, so the anesthesia by electrophoresis both BP of the patient is relatively long and causes discomfort.

Known attempts liquid delivery for electrophoresis to PSU using an ear swab designed to hold the liquid in the outer ear canal. For example, see U.S. patent No. 5674196 issued by Donaldson et al. However, earplugs such as those described in Donaldson, and other currently known earplugs, which have several disadvantages. For example, most ear swabs is designed to prevent fluid in the ear canal, and not to hold the liquid inside passage. Currently known and described previously earplugs in most cases not sufficiently correspond to the curved anatomy of the external ear canal and, therefore, do not provide a snug fit in ear canal at least some (and in some cases all) patients. Thus, existing earplugs are usually not able to hold the fluid inside the ear canal, which significantly impedes or prevents delivery of anaesthetic substances by electrophoresis, if the patient is in the upright position. Moreover, the previously described earplugs intended for use in the electrophoresis procedure, do not solve problems such as the formation of bubbles in the drug solution for electrophoresis, which can inhibit the interaction between electrode and solution.

Based on the above, it is preferable to have improved devices and systems for medicinal electrophoresis eardrum. Ideally, such devices and systems will allow you to enter an anesthetic substance by the method of electrophoresis of the patient, finding the Musya in a vertical position. Also ideally, such devices and systems will provide simultaneous electrophoresis BP on both sides. At least some of these problems can be solved by various embodiments of the present invention.

DETAILED description of the INVENTION

Figure 1A shows the outer ear. The outer ear includes the main element, known as the ear or auricle 100. The outer ear acts as a funnel, directing the sound into the inner ear. The main elements of the ear are the tip 102, the auricle 104, the antihelix 106, curl 108, rook 110, a triangular hole 112, external auditory meatus 114, tragus 116, proteomelab 118.

The figure 1B shows the image in terms of the inner and outer parts of the ear. The auricle 100, as shown, is connected with the outer auditory passage 118, or ear canal. Ear canal 118 is depicted as a relatively direct way, but in fact the passage, as a rule, has a more curved, tortuous structure. Ear canal 118 connects the middle ear 120, which includes the tympanic cavity 122. Middle ear 120, in turn, is connected with the inner ear 124. Tympanic cavity 122, as a rule, holds air cavity behind the outer part, called the eardrum. In the case of infection of the middle ear 120 inside the tympanic cavity 122 accumulates the liquid. Fluid accumulation causes of human infection of the middle ear pain. Middle ear infections are common in young children. To alleviate the suffering by drum puncture the membrane for evacuation of the liquid, this manipulation is known as tympanotomy. Before the procedure tympanopuncture the patient undergoes General anesthesia, but this anesthesia is not preferred due to the high cost and health risks. The preferred alternative in this case is local anesthesia of the tympanic membrane by means of drug delivery by electrophoresis. Thus, the patient can be awake during the operation. The devices and methods of local anestesiologia eardrum disclosed in co-assigned application for U.S. patent No. 11/962073 and 11/749,729, the content of which is fully incorporated herein by reference.

Figure 2A presents electrophoresis system 200 for anestesiologia tympanic membrane made in accordance with one embodiments of the invention. The system 200 includes earplugs 202 and the electrode 206. Ear swab 202 may include a flexible sealing element 204, the distal portion 208, the proximal portion 210 and receiver 212, which connects these two parts. Tube 212 is more flexible in relation to bending than the distal part 208 and the proximal portion 210. This is a distinct advantage, because ear canal usually is a winding passage, it is necessary that th is would be the distal part 208 and the proximal portion 210 located at the opposite ends of this winding passage. Ear swab 202 should preferably be bent and adapted to form a tortuous passage, without blocking the tube 212. In an alternative embodiment, the ear pad 202 may be pre-bent and formed so that its shape corresponds to the shape of the tortuous passage of the ear canal. To obtain the desired flexibility ear swab 202 may be made of a flexible polymeric material, such as silicone.

The distal portion 208 may include a rigid member 214. Rigid element 214, in General, may be in the form of a cylinder or tube, and having an inner edge 216 which prevents the exit of the electrode from the distal part 208. Rigid element 214 may be made of metal or polymer, which increases the structural strength of the distal part 208. Due to the rigid element 214, the distal part 208 has a higher hardness than the tube 212, thus, the distal portion 208 retains its shape when passing through the winding passage. Rigid element 214 may be associated with distal part 208 or molded into it. In an alternative embodiment, the rigid element 214 is integrated with the distal part 208 and is part of the wall thickness is greater than the wall thickness of the tube 212.

The distal portion 208 may further comprise a sealing ring 218. The o-ring 218 is sealed to Zach who Olivet electrode 206 inside the distal part 208. The sealing ring may be associated with distal part 208 or molded into it, or alternatively it can be integrated between the distal part 208 and the tube 212. The o-ring 218 may be performed in such a way as to pass the liquid in the case, if it experiences a pressure higher than atmospheric, for example pressure, which occur when the introduction of a system 200 in the cavity of the ear filled with fluid. For example, the o-ring 218 may be made in the form of double seal opening in the proximal direction. During testing it was found that 2.2 cm H2O is the best option for the threshold pressure of the sealing ring.

The proximal portion 210 may be stiffer than the tube 212, so that the shape of the proximal portion 210 is maintained during the introduction to the winding passage. The proximal portion 210 may include a side opening 220. Side opening 220 is designed for removing excess fluid from the ear cavity, fluid is withdrawn from the proximal portion 208 and through the tube 212. In an alternative embodiment, a side opening 220 may be positioned on the tube 212. The proximal portion 210 may include a fitting Luer with airtight gasket 222 for connection with the electrode 206, as shown in the figure. The proximal part of viewlocity which may be scabrose part 222 for connection with the tube 212. In an alternative embodiment, the proximal portion 210 may be integrated with the tube 212 and save stiffness due molded inserts, which add rigidity, or thick-walled sections.

Flexible sealing elements 204 are used for forming a sealed connection between the system 200 and the ear canal. Flexible sealing elements 204, as a rule, have an elasticity that is able to deform to take the shape of the ear canal, forming a tight seal. The figure shows two flexible sealing element 204, however, be sure you only need one, and can be used multiple items. The first flexible sealing element 204a may be made in the form of an umbrella oval shaped and integrated into the tube 212 and the distal portion 208, as shown in the figure. In an alternative embodiment, the flexible sealing elements 204 may have a pyramid (triangular or triangular shape. It is established that the ear canal, as a rule, has an oval or triangular shape in cross section. Preferably, between the first flexible sealing element 204a and the most distal part of the system 200, there was a drain 226. The outlet 226 provides additional space in the ear cavity for air bubbles, thus preventing the formation of air pockets in the distal part 208. Second upl is tausi element 204b may be larger than the first sealing element, and can be integrated into the receiver 212, as shown in the figure.

In an alternative embodiment, the flexible sealing elements 204 may include adhesive elements contributing to the formation of a tight connection between the sealing surface elements 204 and ear canal. For example, the adhesive layer can be applied on external (i.e. facing the channel surface of the first sealing element 204a and (or) the second sealing element 204b. An adhesive layer may be covered with a protective tape, which must be removed before the introduction of the device into the ear canal. For these purposes, can be used in various adhesives, for example, temperature-dependent, which at room temperature have reduced stickiness, and when heated in the process of introducing into the ear canal become extremely sticky. Temperature-sensitive adhesive composition suitable for placement and re-placement in complex anatomical structure of the ear to reduce discomfort to the patient. Ear swab 202 can be cooled using a cold compress, which reduces the stickiness and remove the ear pad 202. Examples of adhesive elements can serve as: laying Eakin Cohesive® production CovaTec, Inc. and napkin Pre-Po® production Landec Labs, Inc. In the alternative the option can be used temperature-sensitive adhesive composition, having a high viscosity at body temperature and low viscosity when heated to a temperature above body temperature. In this embodiment, for heating use a warm compress to reduce the stickiness and remove the ear pad 202.

The electrode 206 includes the electrode tip 228, an elongated shaft 230 and the proximal coupling element 232. The electrode tip 228 may have a cylindrical shape corresponding to the interior space of the distal part 208. The electrode tip 228, usually has the form of contributing to the formation of an airtight seal inside the distal portion 208 between the inner edge 216 and the sealing ring 218. The electrode tip 228 also has a size that enables its movable inside the tube 212. The electrode tip 228 is preferably made of silver (purity of 99.9%). It is established that the electrode tip of sterling silver 228, which may be covered with oxidized layer simplifies the procedure of electrophoresis. In devices of the prior art was used electrodes made of stainless steel or gold, which are often caused electrolysis fluid electrophoresis, for example, lidocaine, decreased pH, causing discomfort to the patient. The silver electrode can reduce electrical energy is Liz and reduces thus, the discomfort. In an alternative embodiment, the electrode tip 228 may have a silver coating deposited on another metal, for example stainless steel.

The electrode tip 228, as shown, is made of metal and formed into a cylinder, however, in alternative embodiments, the implementation of the tip electrode 228 may have other configurations, with increased surface area to facilitate electrophoresis. For example, can be used multiple strands of silver wire, grouped like a brush. In another embodiment, there can be several concentric lipotropic different diameters. In another embodiment, may be used silver mesh, arranged similarly to the metal sponge. In another embodiment, can be used tip pressed from the polymer matrix, with a relatively large surface area (e.g., sponge) and gold or silver plating or sputtering. In another embodiment, can be used a woven material with a metallic coating with external insulation or without it, depending on size. In another embodiment, can be used cylindrical body from the inner cells of the distal. Another is ariante implementation may use a coil of silver foil. In another embodiment, can be used tip with notches adapted in size (i.e., smaller diameter) and having open sides. In another embodiment, as the electrode, in the form of a tube or wire, can be used elongated shaft 230 with the proximal seal in the tube 212. In another embodiment, can be used weight with many petals or branches (for example, in the form of a flower), integrated into the surface of the flexible sealing element 204. In another embodiment, can be used soft, stretchy tank with a dielectric outer surface and an inner surface with a silver coating, the distal protruding beyond the distal part 208. In another embodiment, may be used one or more cameras, the surfaces of which have a metallic coating, in the distal part 208. In another embodiment, the electrode tip 228 may have holes and (or) textured surface (e.g., cross-strokes, potraviny, sandblasted) to increase surface area. In another embodiment, the electrode tip 228 may include several types of metals, where one metal (e.g. zinc) plays the role of a sacrificial anode. In other variations is the implementation can be used conveyor (i.e., flexible strip with a metallic coating, which can be used to supply clean electrode surface during the operation. In another embodiment, the receiver 212 may include cleaning elements, which during the rotation cleans the surface of the electrode, providing, thus, a clean surface of the electrode during the operation. In another embodiment, the electrode tip 228 may have a protective coating that prevents corrosion.

The electrode tip 228 can be attached to the elongated shaft 230 by soldering or welding. An elongated shaft 230 can be made of the same material as the electrode tip 228. An elongated shaft 230 may further include a lumen to allow fluid. An elongated shaft 230 preferably should be flexible, allowing the user to pre-attach the elongated barrel shape before the introduction of the system 200 in ear canal. Ear swab 202 may also be inserted before the electrode 206 and, thus, the electrode 206 may have a shape corresponding to the shape of the pre-inserted and deformed accordingly ear swab 202. The shape of the proximal coupling element 232 allows you to form a tight seal with the proximal part 210. The proximal connector, the first element 232 also has electrical connection with the wire 234, what provides the power supply to the electrode 206.

Figure 2B shows the electrophoresis system 200 in the first position, in accordance with one embodiments of the invention. The figure shows the electrode 206, where the electrode tip 228 is in the proximal position within the tube 212. In the first position, the distal part 208 and tube 212 form a channel for the fluid. In the first position, fluid can pass through the distal part 208 and out through the opening 220, as indicated by the arrow.

Figure 2C shows the electrophoresis system 200 in the second position, in accordance with one embodiments of the invention. Electrode 206 is shown with the electrode tip in the distal position within the distal part 208. The electrode 206 may be firmly pressed through the seal ring 218, while you hear a click. Thus, the electrode 206 may be moved from the first position to the second position with an audible confirmation. In the second open position the distal part 208 is closed and no longer forms with the tube 212 channel for the fluid. In an alternative embodiment, the seal ring 218 can pass fluid when the fluid pressure inside the ear canal will exceed the threshold.

Figure 2D shows an alternative implementation of the system electropho is Asa 200. In this embodiment, as the outlet 226 and the distal part 208 include many located on one straight line of holes 236, which are placed proximally over the inner edge 216. The figure shows four holes 236, however, in alternative embodiments, the implementation may be more or fewer holes. Holes 236 may be of any suitable size, for example, in one embodiment, each of the holes may have a diameter approximately equal to 0.64 mm (0.025 inches). Holes 236 contribute to the reduction of the volume occupied medicinal solution and open the large surface area of the electrode tip 228, which, in turn, can reduce the voltage required for the procedure of electrophoresis. During electrophoresis the electrode tip 228 gradually corrode and, thus, requires electrophoresis system more voltage as the electric efficiency of the tip of the electrode is reduced. Experimentally during cadaver testing, it was found that holes 236 10 minutes can reduce the amount of voltage by approximately two thirds, compared with the system 200 without holes 236. Thus, the presence of holes 236 prevents dips and surges in the system. Por the shafts voltage - moments when electrophoresis system does not meet the needs of corroded electrode tip 228 in voltage, and thus, the procedure of electrophoresis may be unexpectedly interrupted. The voltage spikes can cause the patient discomfort.

Figure 2E shows an alternative implementation of the electrophoresis system 200. In this embodiment, system 200 is essentially the same as described above, however, to the distal end of the system 200 is attached to the reservoir 238. The reservoir 238 may be made of soft material, such as thin polymer or woven material. Outside the tank 238 may be covered with a sticky substance, such as the compositions described in this document. Organic residues, such as flakes of skin or ear sulfur, can break away from its place in the process of introducing the system and (or) in the process of electrophoresis. Residues may accumulate on the electrode system 200 and, thus, reduce the active surface area of the electrode. During use, the system is introduced into the cavity of the ear, and the reservoir 238 stick to the surfaces of the ear canal, leading to the tympanic cavity 122. For expansion tank 238 in ear cavity can be used tube, such as a cotton cushion, or expanding foam or spray. In some embodiments, the implementation of the reservoir 238 depict is to place a bottle with double walls. The reservoir 238 prevents the accumulation of organic residues on the electrode, creating a physical barrier between the ear canal and the electrode. The tank can also reduce the loss of medicinal solution, as it prevents the absorption of the medicinal solution in the walls of the ear canal.

In figures 2F-2H are shown alternative embodiments of the system for electrophoresis 200. In these embodiments, the implementation of the system 200 is essentially the same as described above, however, the flexible electrode 240 extends beyond the distal end of the system 200. Flexible electrode 240 may include a dielectric side 242 and the conductive side 244 with a plot of the open metal (e.g. silver). Flexible electrode 240 may be made of a flexible polymer, such as polymid, coextruding with a metal strip. Flexible electrode 240 may be made in the form of a separate tape, curved in the form of a loop, where the inner side of the loop is part of the open metal. Alternatively, we can use several tapes, as shown in the example flexible electrode 246 in figure 2G. The length of extension of the flexible electrode 240 is configured according to the specific anatomy of the patient. In practice, the flexible electrode 240 may interact with the ear canal, as shown in figure 2H, not you whom they shock, as the conductive side 244 is not in contact with the surface of the ear canal. Flexible electrode 204 may deviate from the surface of the ear canal due to its flexible properties. Flexible electrode 240 provides a large surface area of the electrode, thereby increasing the effectiveness of the procedure of electrophoresis. A large area of the electrode surface also helps reduce the formation of bubbles in the drug solution.

In figures 3A-3C shows how to use electrophoresis system 200 for anestesiologia tympanic membrane of an ear of a patient, in accordance with one embodiments of the invention. The figure shows the ear 300 patients in cross section. Initially, the patient takes the position lying on its side so that the ear, requiring surgical intervention, were at the top. Then the fluid electrophoresis 302 is injected into the ear canal, as shown in the figure. After that, the ear pad 304 is inserted into the filled ear canal plugging fluid for electrophoresis inside the ear canal. In General, the ear pad 304 is executed in accordance with the described herein options for implementation. If necessary, the ear pad 304 may be impregnated with a liquid for electrophoresis 302 before the introduction of the tampon into the ear canal.

Figure 3B shows the introduction of electr is Yes 306 into the ear pad 304. The electrode 306 may be flexible, and if necessary, can be pre-bent before the introduction. The electrode 306 may make a distinct noise when introduced into the ear pad 304, feeding, thus, the user sound signal indicating proper installation. After final installation of the electrode 306, the pressure inside the ear canal increases and excess fluid 308 drained from the swab, so the fluid pressure immediately balanced with the atmospheric pressure, as shown in the figure. This is an advantage, as even a slight rise in pressure can cause severe pain in the inflamed ear. After insertion of the electrode 306 to him is energized to start the treatment of the patient. The outer ear may also be processed, as described in this document.

In an alternative embodiment, the first position implies a partial introduction of the electrode 306 in ear swab 304, for example, when the electrode tip 228 is placed in the tube 212, during the initial introduction into the ear canal. After placing the ear pad electrode 304 306 can be moved from the first position to the second position (i.e., operating position when it is fully positioned inside of the ear pad 304.

In another alternative embodiment, the implementation of the population electrode 306 can be completely introduced into the ear swab 304 before the introduction of the tampon into the ear canal. After the introduction of the ear pad 304 in ear canal pressure in the ear cavity increases, and simultaneously the pressure is discharged through the seal in the ear pad 304, which removes excess fluid, when the pressure exceeds the set threshold. The advantage of this variant implementation is that the user does not need to move the electrode when the ear pad is located in the cavity of the ear.

Figure 3C shows the ear and, accordingly, the patient is in an upright position. The device 304 includes a drain 310 from the electrode, causing air bubbles 312 to move to the specified position. The outlet 310 prevents the accumulation of air bubbles directly or partly on the electrode, which can lead to partial or complete loss of treatment efficiency. The presence of the outlet 310 is an advantage, as it allows the use of a system 200 in an upright position, and thus allows the treatment of both ears at the same time.

In an alternative embodiment, the patient may be in a vertical position before the introduction of fluid electrophoresis 302 or ear swab 304. First, the ear canal is entered ear swab 304 with fully adjustable electrode 306. In this embodiment, the electrode 306 includes a separate lumen for filling the ear canal. Liquid for electronic is roporta 302, fill the ear canal, is injected through the electrode 306. After filling the ear canal fluid electrophoresis 302 pressure in the ear cavity increases, and simultaneously the pressure is discharged through the seal in the ear pad 304. Thus, excess liquid is displayed when the pressure exceeds the set threshold. The advantage of this variant implementation is that, if necessary, the fluid can fill both one and both ears simultaneously, the patient may be in a vertical position.

In an alternative embodiment, after placement of the device 304 may be proximally imposed sealing material, as shown in figure 3C. As the sealing material can be used soft pliable material, for example, bone wax (such as beeswax, paraffin or isopropyl). The sealing material may be used singly or as a hermetically attached element device 304, for example, in the structure proximally (e.g., between the sealing element 204b and a side opening 220 on figa) posted by disk. The sealing material becomes plastic when heated to body temperature. In practice, the sealing material can push through and give it the appropriate form in the ear or anatomical on the spine of the outer ear after proper placement of the device 304, as shown in figs. The sealing material may take the form corresponding to the form of the complex anatomy of the outer ear, and to provide a secure fit. The sealing material also provides an airtight seal that allows you to use the device 304 a bit smaller, which, in turn, provides a more rapid and less traumatic introduction of the device into the ear canal as the primary seal in this case is formed by the sealing material, and not by device 304.

Alternatively, in place of or in combination with the sealing material can be used a fabric patch. Tissue patch may have the form of a disk and to be hermetically attached to the device 304 as proximally (e.g., between the sealing element 204b and a side opening 220 on figa) posted by the disk. Tissue patch may include an adhesive material, such as a temperature-dependent formulations described herein. Alternatively, the fabric plaster may contain conventional adhesive composition, such as used in a transparent adhesive bandages Nexcare™ Tegaderm™ production 3M, Inc. In practice, the fabric plaster can push through and give it the appropriate form in the ear or anatomical cavity of the outer ear after proper placement of the device is the STV 304, as shown in figs. Fabric patch can provide as tight seal and secure fit. Thus, tissue patch also allows you to use the device 304 with a size smaller than standard.

The figure 4 shows a set of 400 to anestesiologia tympanic membrane of an ear of the patient by the method of electrophoresis, in accordance with one embodiments of the invention. Set 402 includes a system substantially similar to the devices described in this document. Each system 402 includes ear pad 404 and the electrode 406. As shown, ear swabs can be of different sizes. Set 400 also includes a controller 408, which includes a return electrode 410 is electrically compatible with the system 402. The controller 412 provides a power supply system 402 for the procedure of electrophoresis.

In figures 5A and 5B are front and side, respectively, of the flexible sealing element 500, made in the form of an umbrella, in accordance with one embodiments of the invention. A flexible sealing element 500 includes an integrated fin 502, or spokes. With integrated ribs 502 other cha the tee 504 flexible sealing element 500 can be thinner, than the part having the ribs, thus, a flexible sealing element 500 easily deformed. Thus, the device, which includes a flexible sealing element 500, for example, the system 200 may provide an airtight seal inside the ear canal with less effort than the sealing element, does not have integrated ribs 502. In an alternative embodiment, the integrated fin 502 may be located on the inner part of the flexible sealing device 500.

In figures 5C and 5D are front and side, respectively, of the flexible sealing element 506 in accordance with one embodiments of the invention. A flexible sealing element 506 has a cut out portion 508. The cut out portion 508 are thin layers of material. Cut part 508 thinner than the remaining portion 510 of the flexible sealing element 506, and thus, a flexible sealing element 506 easily deformed. Thus, the device, which includes a flexible sealing element 506, for example, the system 200 may provide an airtight seal inside the ear canal with less effort than the sealing element, having cut out portions 508. In an alternative embodiment, the cut portion 508 may be located on the inner part of the flexible sealing device 506.

On the figures the x 5E and 5F shows in perspective and in front, accordingly, the flexible sealing element 510 in accordance with one embodiments of the invention. A flexible sealing element 506, as shown, has the shape of a pyramid or triangle. A flexible sealing element 506 has three sides, creating a tight seal of the ear canal. The cross-sectional shape of the ear canal is not round, but generally triangular. Thus, a flexible sealing element 510 tightly and effectively forms a tight seal inside the ear canal.

In figures 6A and 6B are rear and side, respectively, of the ear swab 600 in accordance with one embodiments of the invention. Ear pad 600 includes a main portion 602, which may include a tubular element and at least one flexible sealing element, as broadly described in this document. Ear swab also includes the behind the ear part 604. In previous devices as locking mechanism ear swabs were used design headphone type. Such devices of the prior art cause inconvenience or discomfort to the user (particularly small children), and as a result the patient has violated the procedures for electrophoresis. The behind the ear part 604 may be made of a flexible polymer such as silicone, and may also b is to be integrated with the ear pad 600. The behind the ear part 604 may also include a frame construction made from a flexible polymer wrapped around the rod (e.g., wire). The rod can be easily deformable, so that the ear hook 604 could be arranged in a shape corresponding to the profile of a specific ear. Alternatively, the rod may be elastic, allowing a constant force acts not on the outer ear, and the ear pad 600.

Figure 6C shows an ear swab 600 in use, in accordance with one embodiments of the invention. The behind the ear part 604 wraps around the leg curl 606 ear. The behind the ear part 604 has advantages compared with other designs of the prior art, as it has a relatively low weight and does not interfere with the patient.

Figure 6D presents a side view of the integrated ear pad 608, made in accordance with one embodiments of the present invention. Ear pad includes a main portion 610, which, in turn, includes power supply and control unit. The control unit functions as a control unit 412 in figure 4. The main part 610 may include control buttons for starting and stopping procedures of electrophoresis. The main part 610 may include one or more adhesive pads. An earmold 608 also includes a flexible bridge 612, having bent the th profile. Flexible bridge 612 can be made of a flexible polymer, such as rubber, and may have a flexible metal rod. Ear swab 614 may have a swivel connection with a flexible bridge 612. Ear swab 614, in General, can have the same design as earplugs described in this document. The cable 616 departs from the main part 610 and attached to the return electrode 618. The return electrode 618 may include a latch to attach to other return electrode.

Figure 6E shows the integrated ear liner 608 in use, in accordance with one embodiments of the invention. The main part 610 may be placed, as shown, with the curl, and can be taped to the patient's skin. Flexible bridge 612 wrapped around the curl, and the ear pad 614 is inserted into the ear canal. Integrated ear liner 608 supports ear swab 614, preventing unwanted shifting and creating a constant reference force, providing a tight seal. By adjusting the flexible bridge 612 can increase or decrease the reference force. Ear swab 614 can be rotated, thus, integrated ear liner 608 can be used on both ears. The return electrode 618 may be glued to the skin of the patient to provide feedback electrical the CSOs path for the control unit. Because integrated ear liner 608 includes an integrated control unit, the patient can freely move during the procedure.

Figure 6F shows the integrated ear pad 620 to use, in accordance with one embodiments of the invention. Integrated ear liner 620 has a design similar to the design ear pad 608 in figure 6D, however, the control unit 622 is placed separately from the lining of the return electrode. Integrated ear liner 620 also includes a flexible body 624, which completely covers the curl of the ear. Flexible body 624 may be made of a flexible polymer, such as rubber, and may have a flexible metal rod. Flexible body 624 can be adjusted depending on the anatomy of the ear to prevent unwanted displacement, and to provide continuous support efforts, forming a tight seal.

Figure 7A shows an ear swab 700 in accordance with one embodiments of the invention. Different areas of the anatomy of the ear have different levels of electrical resistance. The electric current is preferably passes through a region with a low resistance. For example, the eardrum has a lower resistance compared to the cartilaginous areas in the ear canal. You must prevent is ratite unwanted electrical contact with the areas with the greatest resistance it is also necessary to limit the magnitude of the delivered current to provide a comfortable condition of the patient. The location of the electrode as close as possible to the eardrum contributes to the achievement of a positive result, as it reduces the overall delivery path of the current. However, as we know, the ear canal has a winding structure, therefore, to place the electrode as close as possible to the eardrum, not touching other areas in the cavity of the ear, is quite difficult. Ear swab 700 solves these problems.

Ear pad 700 includes a sealing body 702 for a tight fit ear pad 700 in the ear canal. The design of the sealing body 702 similar in design to the other ear swabs described in this document. The sealing body 702 may have gaps and holes to fill the ear canal, or not to have any. Ear pad 700 includes an insulating body 704, passing through the thickness of the sealing body 702. The extended portion 706 of the insulating body 704 comprises an electrode 708. The presence of the extended portion 706 is an advantage, as it electrode 708 extends beyond the sealing body at a sufficient distance and in the process is closer to the eardrum. The distal portion 706 may also come into contact with areas of the ear canal, providing, however, the centrifugal what Yu electrode 708.

The extended portion 710 has a plurality of longitudinal sections 712, which provide fluid access to the inner electrode 714. The extended portion 710 may be made of hypotrophy, trimmed and covered with an outer insulating layer. The presence of the extended part is an advantage since it reduces the number of required parts, and reduces the density of the electric current through the use of a relatively large surface area for the electrode 714. As installed, the reduced density of the electric current more comfortable procedure for the patient. Alternatively, the convex portion 710 may be omitted, and also can be used more or less longitudinal sections 712, as shown in the figure.

Figure 7D presents a perspective view of an alternative execution of the extended portion 710, which can be used, for example, with an ear swab 700 presented on figure 7A. The extended portion 710 includes an insulating areas 716a, 716b and the electrode 718. The electrode 718 may be made of Chinese alloy, such as alloy Titus is Nickel. Thus, when the contact electrode 716a with portions of the ear canal electrode 718, as needed, can easily change direction. The electrode 718 may be longer than shown in the figure, and may include a few insulating sections 716b for further extension of the electrode 718 and placing it next to the tympanic membrane.

The extended portion 728 is the C of the outer insulating material 728 and the inner conductive portion 730. The extended portion 726 may be made of Chinese material, such as an alloy of titanium, Nickel, and have a thin proportions, for example, less than 0.127 mm (0.005 inches).

In the figure 7G presents a perspective view of an alternative execution of the extended portion 732 that can be used, for example, with an ear swab 700 presented on figure 7A. The extended portion 732 includes an outer insulating element 734 and several electrodes 736. Several electrodes 736 are within the insulating element 734. The advantage of this configuration is that it significantly increases the area of the conductive surface and, thus, contributes to the reduction of the density of electric current. Thanks to this configuration, during this procedure, electric current is directed distally towards the eardrum.

In the figure 7H presents a perspective view of an alternative execution of the extended part 738, which can be used, for example, with an ear swab 700 presented on figure 7A. The extended part 738 is similar to the extended part, presented in figure 7F. However, the electrodes 742 are isolated until the most distal point, as shown in the figure.

The medicinal solution can be introduced into the ear canal before the introduction of the tampon foam 900, or after insertion of the tampon due to the structure of the swab foam 902, which has open cells. Due to the porosity of the swab foam medicinal solution can penetrate the entire length of the perforated tube 904, thus increasing the surface area of the electrode through perforated holes in the perforated tube 904. The porosity of the swab foam also prevents the increase in pressure during the procedure of electrophoresis.

Figure 9B shows the balloon device foam 910 in accordance with one embodiments of the invention. Balloon device foam 910 includes an electrode 912.

The cylinder Fe is inimi walls 916 may be glued to the side of the electrode 912, and then partially inverted for forming a double wall. Then, in the space between the walls is introduced swab foam 914. The distal portion of the balloon 916 can be connected to the retractable connecting element 918, such as a T-shaped connector 88207 company Qosina Corp.

In practice, the retractable connecting element 918 is vacuum, which causes the swab foam 914 to shrink. Then the balloon device foam 910 is inserted into the ear canal. Thereafter, the vacuum is stopped, which causes the expansion of the foam 914. Advanced foam 914 puts pressure on the bladder with double walls 916 in contact with the walls of the ear canal, thereby tightly plugging the drug solution inside the ear canal. Tat for inflating the balloon is not used positive air pressure, the danger of rupture of the container no. For re-compression foam 914 and facilitate easy removal of the swab from the ear re-apply the vacuum.
