    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: An insertion needle facilitates the implantation of an electrode array carried on a flexible, foldable or compressible, subcarrier or substrate. Such subcarrier or substrate folds or compresses during implantation, thereby facilitating its insertion using the insertion needle. Once implanted, such subcarrier or substrate expands, thereby placing the electrodes in a desired spaced-apart positional relationship, and thus achieving a desired electrode array configuration. The insertion needle has a lumen with a non-circular cross-sectional shape, e.g., having a width greater than its height, to facilitate sliding the folded or compressed paddle-type electrode array therein, and further includes a longitudinal slit.

    摘要: An implantable electrode array, adapted for insertion into a cochlea, provides a multiplicity of exposed electrode contacts, each having a shape, geometry, or makeup that aids in controlling the current flow and current density associated with the electrode contact as a function of position on the electrode contact. In one embodiment, the shape or geometry of the exposed electrode contact controls the contact surface of the electrode contact in a way that varies the current flow and current density as a function of surface area position on the electrode, thereby focusing most of the current to flow through the center of the electrode contact. In another embodiment, the electrode contact is coated with a dielectric or other material that controls the surface contact impedance as a function of distance from the center of the electrode, again focusing most of the current flow through the center of the electrode contact. In yet a further embodiment, the exposed electrode contact surface area is masked with an insulator to prevent conduction of current at various locations on the surface of the electrode contact. Separately, or in combination with any of the above embodiments, the exposed electrode contact surface and/or the entire electrode array may be coated with a selected substance or drug compound that diffuses into the tissue and liquids surrounding the electrode. Such substance or drug compound is selected to elicit a desired result, e.g., to inhibit fibrous tissue or bone growth in the vicinity of the electrode contacts; to promote healing of damaged tissue in the region of the electrode contacts, to prevent neural degeneration, or to promote neural regeneration.

    摘要: A hair clip for use with a cochlear implant system retains a headpiece assembly, including a transmitting coil, in an aligned position relative to an implanted stimulator. In one embodiment, the hair clip provides a retention system that uses a magnet which forms part of the transmitting coil. A comb or plurality of prongs forms part of the retention system. In another embodiment, the comb has central teeth that are made from ferromagnetic material, and typically also has a non-central teeth that are made from non-ferromagnetic material. The comb is placed and secured in the patient's hair over the area where a cochlear implant is implanted. The transmitting coil is then placed next to the comb, and the magnet within the transmitting coil attaches to the ferromagnetic teeth of the comb. In another embodiment, the transmitting coil is housed in a headpiece, and the headpiece and comb or hair clip are fastened together, along an edge of the comb or hair clip where the teeth or prongs are bonded, with a hinge attachment spring. In a further embodiment, the hair clip is formed from a single sheet of stainless steel, and a plurality of prongs engage a lower surface of the headpiece while a retaining band, with an integral spring, securely holds the headpiece in place against the prongs. The hair clip is opened by applying a manual force against the spring and retaining band.

    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 implantable electrode array, adapted for insertion into a cochlea, provides improved stability of electrode contact direction. In-line electrodes are spaced-apart along one side of a flexible carrier. The structure of the electrode array facilitates bending of the array with the electrode contacts on the inside of the bend, yet deters flexing or twisting of the array in other directions. The electrode contacts preferably are each made from two strips of metal, arranged in a "T" shape (top view). During assembly, all of the "T" strips are held in position on an iron sheet. Two wire bundles are formed that pass along each side of each "T". The leg of each "T" is folded over to pinch at least one of the wires from one of the wire bundles therebetween. This pinched wire is then resistance welded to the strip. The sides of the "T" are then folded up and touch or nearly touch to form a ".DELTA." shape (side view). The wire bundles going to more distal electrodes pass through the ".DELTA." and are thus engaged by the ".DELTA.". A flexible carrier, made from, e.g., silicone rubber, is molded over and around the wire bundles and folded electrode T's, preferably in a slightly curved shape. The iron sheet is chemically etched away, leaving an array of spaced-apart electrode contact areas along one edge of the flexible carrier, each of which is electrically attached to at least one wire which passes through the carrier. The electrode array can be manufactured using low cost technology; and once made can be easily inserted, removed and reinserted, if required, into the cochlea or other curved body cavity.

    摘要: A microsurgical tool (8), in the form of forceps, allows access and micro-manipulation into very small confined spaces, such as the cochlea. The microsurgical tool includes an activation body (10) and a working head (20). The activation body is made from a pair of leaf springs (11) joined permanently at one end to a sliding bracket (12) and joined at the other end to a central section (15) with removable screws (13). The central section (15) tapers to an extension (15A) that extends to the working head. A push arm (16) has a first end coupled to the sliding bracket (12) and a second end pivotally joined to the working head (20). The working head (20) is made from a first jaw part (21) attached to the extension (15A), and a second jaw part (22) pivotally connected to the second end of the push arm (16). In operation, pressing the pair of leaf springs together forces the sliding bracket to slide forward and close the first and second jaw parts together, while releasing the pair of leaf springs allows the sliding bracket to slide backward to open the jaw parts.
