    摘要: A hybrid cochlear implant hearing aid sytem (10) provides low frequency acoustic energy boost, if needed, and high frequency direct neural stimulation. Tinnitus suppression may also be provided. The neurons responsible for sensing high frequency sounds are located at the basal end of the cochlea. A short basal electrode (52) that extends into the cochlea only at the basal region allows direct stimulation of these neurons by an appropriately-controlled cochlear stimulator (50). The basal electrode array typically has from four to eight electrode contacts (54). The design of the electrode array allows the surgeon to place the array using minimally invasive surgical techniques and requires no cochleostomy. The electrode array is thin, and can typically be inserted directly through the round window membrane to make contact with, or to be positioned in close proximity to, the modiolus wall in the basal region of the cochlea. The hybrid implantable cochlear stimulator and hearing aid system relies primarily on the cochlear stimulator portion of the system for being able to sense high frequency sounds, and relies primarily on normal hearing processes, or other acoustic boosting devices and systems, for being able to sense lower frequency sounds.

    摘要: Embodiments of implantable infusion pumps are provided that use a process of converting a first substance to a second gaseous substance (e.g. by electrolysis) to provide a motivating force to expel a desired fluid (e.g. drug or medication) from the pump into the body of a patient. An expandable sack may be provided around a gas producing electrolytic cell, such that as the gas expands it displaces a portion of the volume originally allocated to the desired fluid, and thereby forces the fluid from the pump. Pumps may be provided with a double septum to allow refilling of the desired fluid while simultaneously allowing removal of the generated gas from the system while using a single needle. Recharging of pump batteries may occur by direct electrical conduction through one or more needles and/or by r.f. energy transfer. Programming of the pump may occur by way of conductive paths provided by one or more needles or by means of r.f. transfer. A pressure regulator may be provided in vicinity to an outlet port of the pump so as to enable more reliable operation of the pump when subjected to changes in ambient pressure. A one-way valve may also be provided to reduce risk of back flow into the pump.

    摘要: An inflatable cochlear electrode array adapted for insertion into a human cochlear includes a flexible carrier on which a multiplicity of spaced-apart electrode contacts are carried, preferably along one side, e.g., a medial side, of the carrier. The flexible carrier also includes an inflatable compartment or section. In one embodiment, the inflatable section is located at the distal tip of the electrode array on a side of the flexible carrier that is opposite the electrode contacts. In another embodiment, the inflatable compartment or section is located along at least one half of the full length of the flexible carrier, forming a spine. In either embodiment, the electrode is readily inserted into the cochlea to a desired depth while the inflatable compartment or section remains in a deflated state. Thereafter, a desired modiolus-hugging position is achieved by inflating the inflatable compartment or section by injecting therein a suitable biocompatible fluid. A method of making an inflatable cochlear electrode is also disclosed.

    摘要: An improved and simplified pressure reservoir is provided for use with an implantable medication infusion pump to maintain a selected medication in liquid form with a pump housing under a substantially constant pressure. The pressure reservoir comprises a hollow structural enclousre having at least one flexible resilient wall and is adapted to be filled with a selected quantity of a pressure fluid, such as a selected fluorocarbon in a liquid-vapor state, prior to mounting of the reservoir as a structural unit into the infusion pump housing. Within the pump housing, the flexible reservoir wall defines one side of a medication chamber, with the pressure fluid undergoing appropriate change of state to expand or contact the reservoir in a manner maintaining the medication under a substantially constant pressure. The improved reservoir can be provided in a variety of structural shapes and/or utilized in pump housings of various size and shape to permit the pump size to be reduced, or, in the alternative, to increase pump medication capacity without increasing pump housing size.

    摘要: An implantable neurostimulation system includes both implantable and external components. Electrical connectivity between the external and implanted components is achieved through a plurality of feedthrough pins located within an insulative wall of a percutaneous port embedded in the skin. The percutaneous port has the general shape and appearance of a small thimble, embedded in the skin with its open end facing outwardly from the skin surface, and with its closed end located below the skin surface, thereby forming a cavity or dimple in the skin. Various plugs or cartridges can be removably inserted into the cavity of the percutaneous port, in various orientations, to facilitate appropriate connectivity between the external and implanted components of the system through selected ones of the feedthrough pins. A mesh edging secured around the periphery wall of the port promotes tissue ingrowth and vascularization, thereby forming a percutaneous seal around the port that prevents infection.

    摘要: A hybrid electrode array includes a basal array section and a distal array section. The basal array section is configured to provide high frequency stimulation. The basal array section is configured to extend into the cochlea up to a region where electrical stimulation provides recovery for high frequency loss. The distal array section is configured to be attached to a distal tip of the basal array section and is configured to extend into the cochlear to a region where electrical stimulation provides recovery for middle to low frequency hearing loss. For progressive hearing loss treatment, the distal array section is not activated during initial stages of hearing loss allowing the patient to rely on a combination of acoustic stimulation and high frequency stimulation provided by the basal array section. As hearing loss progresses, the distal array section is selectively activated to treat lower frequency hearing loss using lower frequency stimulation.
