DESCRIPTION OF THE PREFERRED EMBODIMENT

[0030] The present invention overcomes the prior art limitations by providing a method and device for electrolytic conversion of aqueous humor to treat glaucoma. This method and its device minimize permanent damage to the structures of an eye while relieving the high intraocular pressure from the eye characteristic of glaucoma.

[0031] Referring to FIG. 1, relevant structures of a mammalian eye appear in this figure and provide background information for the anatomical terms used herein. Though this description refers to mammalian eye, the Applicant foresees both human medicine and veterinary medicine applications for the invention. Though this description refers to mammalian eye and eye, that description includes both human and non-human mammal eyes. FIG. 1 provides a cross sectional view of an anterior segment E of the eye. As shown in FIG. 1 towards the upper center, the cornea C is a thin transparent tissue which is part of the outer eye and lies in front of an iris I. The iris includes a pupil P as an opening for the passage of light into the eye for vision. The cornea merges into a sclera M at a juncture known as a limbus Q here shown towards the right. The sclera has an interior layer called the choroid J that extends around the eye but does not cover the interior surface of the lens. A layer of tissue called the bulbar conjunctiva, later shown in FIG. 5 covers the exterior of the sclera M. A ciliary body D extends from an uveal tract (not shown) beginning on the left of the figure. It begins at the limbus Q and extends along the interior of the sclera M to the right ending at the uveal tract K. The uveal tract includes the ciliary body, the iris I, and the choroid. A crystalline lens L of the eye is situated between the iris I and a vitreous fluid F and remains enclosed within a transparent lens capsule as at H. An anterior chamber G is the space between the cornea C and the crystalline lens L, here shown above and outwardly from the lens. A posterior chamber, as at G′, is a space bounded by the iris, ciliary body, and crystalline lens. Both of the anterior and posterior chambers receive aqueous humor B fluid within them to fill them. A trabecular meshwork A here shown outwardly from the lens L at the sclera M, filters aqueous humor from the anterior chamber into drainage channels (not shown), surrounding capillaries (not shown), and lymphatic ducts of the lymphatic system (not shown). Proximate the vicinity of the cornea C and the iris I, the eye has an angle R. The angle R is a portion of the anterior chamber and is filled with aqueous humor B along with the remainder of the anterior chamber. The base of the angle R has the trabecular meshwork A and through there the aqueous humor drains B into microscopic pores (not shown) in the trabecular meshwork and into the general blood circulation/collector channels (not shown). In open angle glaucoma the pores of the trabecular meshwork A have defects and obstruct the flow of aqueous humor. In closed angle glaucoma, the iris comes into contact with the cornea to prevent passage of aqueous humor into the trabecular meshwork. In both forms of glaucoma, the pressure of the eye increases as a result of build-up of the aqueous humor fluid.

[0032] As shown, FIG. 2 provides a cross sectional view of an anterior segment E of the human eye. Here in FIG. 2, the aqueous humor B flows, as shown, from the posterior chamber G′, through the pupil, into the anterior chamber G. The aqueous humor flows from the interior to the exterior of the eye.

[0033] FIG. 3 provides a schematic view of the front portion of an eye with the invention 1 installed thereon. The eye has its classic round, nearly spherical shape as shown with the pupil P and iris I to the left of this figure. Outwardly from the pupil, the anterior chamber G has a generally centered position upon the eyeball and the sclera M extends and enwraps the remainder of the eyeball. This figure shows three muscles S, among others, that orient the eyeball for vision. These muscles are shown attached at the top, the bottom, and the left middle of the eyeball.

[0034] Then FIG. 3 illustrates a method of applying electrolysis, or electrolyzing, formerly vaporizing, aqueous humor of the present invention. FIG. 3 then shows the invention 1 of an implant with an enclosure 2 positioned, or installed, on the sclera M containing a controller 3, a pressure sensor 4, a data transmission module 5, and voltage source 6, or a power source, such as a battery, capacitor, or photocell. The battery may have composition using alkaline, silver nitrate, nickel cadmium, nickel metal hydride, and the like. The battery may also have a recharging capability from its composition using lithium ion, lithium polymer, and a photocell in communication with a capacitor.

[0035] The enclosure has a preferable form of a plastic polymer, such as a silicone elastomer. The enclosure may contain a radiopaque material such as barium sulfate, to make the implant visible in x-ray procedures. The enclosure has a radius of curvature no less than 12 mm and preferably in the range of about 12 mm to about 15 mm. The length of the enclosure is no more than 13 mm and preferably about 10 mm and its width is no more than 13 mm and preferably about 6 mm. The inner surface of the enclosure is flat or preferably concave so as to conform to the curvature of the eye. The invention installs upon an eye so that the conjunctiva covers the electrodes and the enclosure, as later shown in FIG. 5. Electrodes 7, here shown at least two in number, that is, as a pair extending from the enclosure, enter the sclera posterior to the limbus and have a position within the angle R of the anterior chamber. The electrodes enter the anterior chamber of a mammalian eye. The electrodes have sufficient length to span the thickness of the cornea and the sclera. Alternatively, the electrodes have sufficient length to span solely the cornea or solely the sclera. Alternatively the electrodes have a position through a surgically constructed scleral tunnel before entering the angle of the anterior chamber. The electric field between the pair of electrodes causes electrolysis of aqueous humor and its conversion into hydrogen and oxygen gases. The surrounding tissue then absorbs the gases, including the sclera. Also, the electrolytic conversion of aqueous humor to gases results in reduced fluid volume and reduced intraocular pressure. The electrodes span the thickness of the sclera and the encasing conjunctiva. Thus, the electrodes have a length between about 250 microns to about 750 microns. The electrodes connect to the voltage source 6 and the controller 3 situated within the enclosure 2 that optionally contains the pressure sensor 4. The present invention has a size of approximately 12 millimeters by 12 millimeters and a thickness compatible with implantation on the surface of an eye and secured by sutures and/or tissue adhesive. The present invention has its electrodes 7 extending outwardly from it. The electrodes preferably have a coupling to the enclosure 2 by a flexible lead, or alternatively by a rigid lead. The electrodes may also serve as prongs that stabilize the invention in position.

[0036] The present invention can be implanted using known ophthalmological surgical techniques and, with reference to FIG. 3 and FIG. 5, a brief discussion of the surgical implant procedure follows. The surgeon makes an initial incision in the conjunctiva posterior to the limbus. The enclosure is inserted through this incision and positioned on the sclera. Eyelets, in the forefront of the enclosure, are used to suture the enclosure to the sclera. The electrodes are inserted through the sclera posterior to the limbus and into the angle of the anterior chamber. Alternatively, a surgically constructed scleral tunnel may serve as a protective conduit for electrodes which are then surgically guided into the angle of the anterior chamber. The exposed portion of the enclosure or electrode is covered with graft material consisting of sclera, amniotic tissue, or pericardium.

[0037] FIG. 4 provides a block diagram of the invention according to the principles of the present invention. With the enclosure 2, the invention 1 has its voltage source 6, the pressure sensor 4 as an optional component, a circuit for recharge as at 8, the controller 3, an output circuit 9, and the pair of electrodes 7. The recharge circuit in cooperation with the transmission module receives an external signal and converts it to electrical power for delivery to the power source. The voltage source has electrical communication to the controller which distributes power to the remainder of the invention. The pressure sensor, the recharge circuit, and the data transmission module provide data input to the controller. The controller then outputs, or metes, a regulated amount of voltage through the output circuit 9 which then energizes the electrodes 7 at the appropriate strength for the opportune time.

[0038] FIG. 5 provides a cross sectional view of the invention when implanted in an eye, particularly upon the sclera M and beneath the conjunctiva N as shown. The sealed enclosure 2 contains some or all of the previously described components. Aqueous humor B produced by the ciliary body as a portion of K flows into the anterior chamber G beneath the cornea C. The enclosure is implanted beneath the conjunctiva N posterior to the limbus L. Electrodes 7 exit the enclosure then enter the anterior chamber G through the limbus L, where they contact the aqueous humor.

[0039] The electrodes conduct charge and may use a variety of materials, including but not limited to titanium, nickel titanium, brass, nickel, aluminum, platinum, iridium, iridium oxide, titanium nitride, tantalum, stainless steel, other steels, graphite, alloys or combinations thereof. In an alternate embodiment, the electrodes are either titanium or platinum. The electrode may also have composite construction, whereby different sections have a construction from different materials. In the preferred embodiment, the electrodes have a medical grade material safe for prolonged use inside an eye. The electrodes are embedded in a non-conductive sheath that serves as an insulating barrier so other areas of the eye are not affected by the electric field. The insulating sheath preferably has sufficient thickness to prevent both current flow and capacitance coupling with the tissue.

[0040] The electrodes may have various shapes such as straight, angles or curved, which provide for an optimal electric field while avoiding contact with intraocular tissue. The configuration and location of the electrodes have optimal form to maximize the effectiveness of the electric field in aqueous humor while minimizing the impact on surrounding tissue. As mentioned above, voltage applied across the electrodes 7 creates an electric field. The typical electric field strength is between about 1 to 25,000 Volts per centimeter, and preferably about 1 to about 250 Volts per centimeter.

[0041] The controller 3 regulates the voltage applied to the electrodes which may have continuous or intermittent form, that is, the controller metes power to the electrodes. The controller and voltage source may have the form of a single device. The electric field generated by the electrodes results in electrolytic conversion of aqueous humor to hydrogen and oxygen gases as noted above. The spacing of each electrode in the pair ranges from about 100 to about 1000 microns. A close spacing of electrodes permits high levels of electrolysis with the use of moderate voltages and minimal power consumption than a wider spacing.

[0042] The shape of the electrodes 7 may take many forms. A preferred embodiment of electrodes though has sharp tips upon the electrodes so that they perforate the sclera during usage. Electrodes with sharp tips enhance electrolytic conversion of aqueous humor to gases. Piercing the sclera for placement of electrodes in the anterior chamber occurs more readily using electrodes having sharp tips. Though the electrodes have tips, the tips may have a round conical shape, a beveled shape, an arrowhead shape, a narrow pin, and the like.

[0043] A plurality of sources may provide voltage to the invention, as at 6. The voltage source 6 includes a rechargeable battery, such as a lithium ion or lithium polymer, a photocell, or a capacitor. A voltage source can be recharged by a radio-frequency identification, or “RFID,” link or other type of electric recharging circuit. The surgeon selects the voltage source 6 based upon available space, amount of current needed, lifespan of the device, cost, installation methods, and the like. The voltage source supplies charge to the electric field between the electrodes generally between about 1 to about 500 volts, and preferably about 1 to about 250 volts.

[0044] The pressure sensor 4 has a location upon the sclera M so that it monitors intraocular pressure and provides feedback to the controller. The Applicant foresees deploying a pressure sensor as a component of the invention so that it monitors intraocular pressure before, during, and after usage of the invention. A controller operating in concert with the pressure sensor can regulate the amount of voltage passing to the electrodes. The pressure sensor acts in concert with the power source and controller to provide current only when needed. The controller has a program that releases electrical power to the electrodes only when the pressure reaches a certain threshold. The controller accepts adjustments to its program remotely to adjust for a desired pressure threshold. In an alternate embodiment, the Applicant also foresees combining a temperature sensor with the pressure sensor. The temperature sensor serves as a fall back to the pressure sensor and acts in concert with the power source and controller to restrict current when no longer needed. The controller has a program that ceases delivery of electrical power to the electrodes when the temperature exceeds a certain value, typically about 95° C. at about sea level pressure, and lower temperatures at lower pressures typically at higher altitudes.

[0045] The controller can also modulate the duration of electric current reaching the electrodes. A constant duration of current produces constant electrolysis of aqueous humor while, intermittent current produces an electrolysis used only when the level of pressure rises sufficiently to warrant electrolysis of aqueous humor. The duration of current and the voltage level vary by the controller to regulate the intensity of electrolysis of aqueous humor. Preferably, the current supplied in the invention for electrolysis of aqueous humor is not continuous. This type of current markedly reduces the volume of battery.

[0046] More particularly, the controller provides the invention with a voltage of an amplitude between about 0.1 volt and about 60 volts. The controller imparts into the invention, through the output circuit, electrical stimulation of a current having a pulse amplitude of between about 10 microamps to about 25 milliamps. The stimulation also has a current having a pulse width between about 50 microseconds to about 2700 microseconds. The controller also has a voltage limiting circuit that limits the voltage emitted by the stimulation component during usage.

[0047] FIG. 6 provides a schematic view showing an alternative embodiment of the invention with suture holes for securing the invention to the sclera. The suture holes appear upon an extension 15 of the inner portion of the enclosure 2 that includes a plurality of small eyelets 16, here shown as two. The extension 15 has a generally rectangular form with a longitudinal edge, 15a, outwardly from the enclosure and two spaced apart lateral edges, 15b, spanning from the longitudinal edge to the enclosure. The lateral edges have a beveled appearance in this figure. The lateral edges have much less length than the longitudinal edge as shown. The eyelets 16 serve as suture holes that a surgeon uses to secure the invention to the sclera. The surgeon loops suture material, such as nylon, through the eyelets and secures them by attachment to the sclera.

[0048] Generally centered upon the extension 8, an electrode 7 extends outwardly from the extension and the remainder of the enclosure 2. Each electrode has a sheath 10 of a non-conductive, insulating material. The insulating material spaces two adjacent electrodes a particular distance apart. The insulating material also prevents electrical discharge to intraocular structures that are not targeted for electrolysis. Further, the insulating material isolates an anode 11 portion of the electrode from the cathode 12 portion of the electrode.

[0049] FIG. 7 illustrates a further embodiment of the invention when used with a conventional glaucoma drainage device. FIG. 7 also shows a perspective view of a tubular glaucoma drainage shunt and the invention 1 mounted upon the exterior surface of an eye ball, or sclera M. The shunt has fluidic communication as at 13 that enters the anterior chamber. Electrodes 7, extending from the enclosure 2 of the invention 1, penetrate the outer shell of the glaucoma shunt as at 13a and into the invention's lumen as at 14. The electrodes 7 also mechanically stabilize the position of the enclosure 2 on the exterior surface of a glaucoma valve, not shown. The electrodes, present in the lumen of the glaucoma shunt, provide an electric field for electrolysis of aqueous fluid. The gasses from electrolysis dissipate through the channels for aqueous humor outflow, normally present in glaucoma shunts. The enclosure 2 of the invention contains the voltage source 6 and the other components of the invention as previously described. The components also include the pressure sensor 4 that provides information to the controller. The controller then maintains equilibrium between the intraocular pressure in an eye and the degree of electrolysis.

[0050] The present invention can be implanted on the surface of a glaucoma drainage shunt using known ophthalmological surgical techniques. Referring to FIG. 7, the Applicant describes the surgical implant procedure suitable for the invention. The surgeon retracts the conjunctiva, or incises it, and then inserts the enclosure 2 inserted through this opening. Electrodes 7, exiting the enclosure 2, then penetrate the top of a glaucoma drainage shunt under the surgeon's guidance and enter the lumen of the shunt. The surgeon penetrates the shunt by drilling the roof of the glaucoma drainage shunt with a small drill bit or by piercing the top surface of the glaucoma drainage device with sharp-tipped electrodes. The electrodes also mount the enclosure securely in position upon the outer shell, or lumen 14, of the glaucoma shunt. Electrolysis of aqueous humor within the lumen of the glaucoma drainage eliminates the cause for the formation of a bleb and its potential complications.

[0051] The device of the invention permits a surgeon to utilize this method to thwart the progression of glaucoma: reducing intraocular pressure in a mammalian eye. The method provides at least two electrodes and a lead extending from each electrode, provides a controller receiving the leads and having an output circuit in communication with the leads to the two electrodes so the controller receives external communications through a transmission module, providing a power source in communication with the controller so it metes power into the leads of the electrodes, provides a recharge circuit that receives an external signal and generates electrical power for the power source, placing the controller, the power source, the output circuit, and the recharge circuit within an enclosure. The method installs the enclosure upon the sclera of a mammalian eye, inserts the two electrodes into the anterior chamber of a mammalian eye, regulates the spacing of the two electrodes and the field strength generated by them, regulates the voltage, current, and duration of electrical power application by the controller through the output circuit for dispensing into the electrodes. The method has its goal of upon application of electrical power to the electrodes a portion of aqueous humor electrolyzes and exits a mammalian eye thus lowering its pressure.

[0052] From the aforementioned description, a method and device for electrolysis of aqueous humor to treat glaucoma has been described. The method and device for electrolysis of aqueous humor to treat glaucoma is uniquely capable of converting aqueous humor into its constituent gases using intermittent electrical current until intraocular pressure falls below a threshold value. The method and device for electrolysis of aqueous humor to treat glaucoma and its various components may be manufactured from many materials, including but not limited to, vinyl, polymers, such as nylon, polypropylene, polyvinyl chloride, high density polyethylene, polypropylene, ferrous and non-ferrous metal foils, their alloys, and composites.
