    摘要: A lead assembly and a method of making a lead are provided. The method of making a multi-contact lead assembly comprises placing monofilament placed in the void spaces not occupied by the plurality of conductor wires and, in one embodiment, thermally fusing the monofilament to the like material spacer by applying heat just below the melting temperature of the monofilament and spacer material. Alternatively, the monofilament and spacer may be of different materials and heat is applied to cause at least one material to thermally reflow or melt. The conductive contacts may be located at either the distal end and/or proximal end of the lead. Oversized spacers may be used in order to provide extra material to fill voids during the thermal fusion/reflow process.

    摘要: A curved paddle electrode allows the electrode to be placed over a relatively flat or oval shaped nerve bundle attached to fascia tissue without having to separate the nerve bundle from the fascia tissue. The electrode includes at least one suture hole that allows the electrode to be held in place over the nerve bundle through a clip-on stitch, or equivalent. In one embodiment, the curved paddle electrode provides a tripolar electrode configuration that allows three spaced-apart parallel electrode contacts to be positioned transverse to a target nerve bundle. Such electrode configuration allows bipolar or tripolar stimulation to occur. Other embodiments employ less or more than three electrode contacts. A preferred application of the curved paddle electrode is for the treatment of erectile dysfunction (ED), where the electrode is placed over the neurovascular bundle attached to the rectal fascia tissue near the rectum.

    摘要: A cochlear electrode array is adapted for implantation within the basal end of the scala tympani duct of a human cochlea. A first embodiment of the cochlear electrode array (10) comprises a skinny, elongate carrier (12) of from 6-8 mm in length. Four to eight spaced-apart electrode contacts (14) reside along one of the flat sides of the carrier, each of which is connected to a respective wire (22) embedded within the carrier. The wires exit a proximal end of the carrier via a wire bundle. The wire bundle, in turn, is connectable to an implantable cochlear stimulator (ICS) or equivalent pulse generator. The electrode array (10) is inserted into the relatively straight portion of the basal end of the scala tympani duct of the cochlea through a small slit (42) made in the round window membrane that separates the cochlea from the middle ear. The slit is oriented so as to place the electrode contacts facing the modiolar wall (32). The proximal end of the carrier may include flexible flaps (16) or tines that maintain the electrode array in its desired position within the basal end of the cochlea. Such tines or flaps further help seal the carrier against the slit opening to present fluids from escaping the cochlea. The cochlea thus remains filled with fluid which can activate hair cells as fluid waves are established through motion of the round window membrane. In use, electrical stimulation is provided only to the basal end of the cochlea through the electrode array to supplement hearing of high frequency sounds. Normal hearing (activation of hair cells through fluid motion) occurs at the apex and middle regions of the cochlea for sensing lower frequency sounds. A second embodiment of the cochlear electrode (100) is made by forming a small (120) of about 0.4 mm diameter on the end of a very fine flexible platinum/iridium (Pt/Ir) wire (140). At a proximal end of the wire, a suitable connector (540) allows the wire to be detachably connected to a pulse generator (500).

    摘要: A method of making an implantable electrode array, adapted for insertion into a cochlea, includes the steps of: (a) forming electrode contact pieces made from a precious, biocompatible material into a desired shape; (b) attaching the electrode contact pieces to a foil sheet made from a non-toxic but chemically-active metal; (c) connecting a wiring system to the metal contact pieces; (d) molding a flexible polymer carrier around the electrode contact pieces and wiring system while such are held in place by the foil sheet; and (e) etching away the foil sheet, leaving the electrode contact pieces exposed at a surface of the molded polymer carrier. The exposed electrode contacts are made so as to have 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.

    摘要: An implantable microphone assembly for use with a hearing prosthesis, such as a fully implantable cochlear stimulation system, includes a diaphragm mounted to an outside surface of an hermetically sealed case. The mounting is made, in one of various embodiments, by way of an hermetic weld around the diaphragm circumference. A gap is created on the underside of the diaphragm when the diaphragm is lifted with internal pressure. An acoustic channel or groove is formed in the wall of the hermetic case to which the diaphragm is mounted. A first end of the channel or groove opens into the gap at a location that is at or near the center of the underside of the diaphragm. A second end of the channel or groove opens to the interior of the hermetic case at a location that is near the periphery of the diaphragm. An acoustic transducer is placed inside the hermetic case and coupled to the second end of the acoustic channel or groove so as to sense variations in pressure that occur in the gap due to deflections of the diaphragm caused, e.g., by external sound pressure. The interior space inside of the hermetic case directly underneath the diaphragm may be used to house and mount other components, such as a battery. The interior of the hermetic case, which interior includes the gap and acoustic channel, is pressurized in order to lift the diaphragm to form the gap and enable the diaphragm to move in response to external forces, such as forces created by sound impinging the skin above the area where the implantable microphone is implanted.

    摘要: A threaded grommet, having an axial passageway therethrough, and made from a biocompatible material, such as titanium, is screwed into a cochleostomy made in the bony tissue adjacent the round window in order to provide a minimally-invasive access port into the cochlea. The threads included on the outside of the grommet engage the bony tissue and form a tight seal that holds the grommet securely in position. Such tight seal prevents cochlear fluids from escaping from inside of the cochlea. The axial passageway through the center of the grommet provides an opening, i.e., mechanical access, into the base end (the end of the cochlea nearest the round window) of the cochlea. Drugs, steroids, tissue-growth-inhibiting fluids, and the like, may be controllably delivered through the access hole into the cochlea, which access hole may be plugged when not needed. Additionally, an electrode array, e.g., a relatively short electrode array may, be inserted into the cochlea through the access hole. A preferred electrode array has from four to eight electrode contacts spaced apart along a flexible carrier. The flexible carrier is about 6-8 mm in length. The electrode contacts may be connected, in conventional manner, to suitable implantable cochlear stimulator (ICS), or equivalent pulse generator. Neither the grommet nor the short electrode array interfere with the normal hearing processes within the cochlea. Hence, both electrical stimulation and normal hearing processes may occur simultaneously within the cochlea.

    摘要: A cochlear electrode array is adapted for use with a hybrid hearing aid system. The cochlear electrode array has a carrier on which spaced-apart electrode contacts are carried, and in one embodiment is formed in the shape of a blade, being flat in one direction and thin in another direction. In another embodiment, side fins extend out from opposing sides of the carrier on which the electrode contacts are carried. The blade electrode array, or electrode array with side fins, is adapted for minimally-invasive insertion into the inner ear. More particularly, the blade or finned electrode is designed to be inserted through a soft cochleostomy so as to reside between the spiral ligament membrane and the cochlear bony tissue along a lateral side of the cochlea, near the basal end of the cochlea. As such, the blade electrode does not penetrate into the scala tympani or other ducts of the cochlea, and the cochlea remains free to perform its normal hearing functions to the extent that such normal hearing functions can be performed.

    摘要: A spiral shield for an implantable secondary coil confines the electrical field of the coil, and thus prevents capacitive coupling of the coil through surrounding dielectrics (such as human tissue.) Known implantable devices receive power inductively, through a secondary coil, from a primary coil in an external device. Efficient power reception requires that the coils be tuned to the same resonant frequency. Use of the spiral shield results in predictable electrical behavior of the secondary coil and permits the secondary coil to be accurately tuned to the same resonate frequency as the primary coil. To further improve performance, spacers made from SILBIONE®LSR 70 reside between turns of the coil to reduce turn to turn and turn to shield capacitances. Reducing the capacitances prevents excessive reduction of the self resonant frequency of the coil. The coil is imbedded in SILBIONE®LSR 70, allowing for a thin and flexible coil.

    摘要: An implantable electrode assembly includes a leading section attached to the distal end of an electrode array. The electrode array has electrodes spaced along its length. Cochleostomies are drilled at both the base and apex of the cochlea. The leading section is inserted through the basal cochleostomy and promoted to the apical cochleostomy. A forward end of the leading section is then pulled through the apical cochleostomy, which causes the electrode array to be pulled into the cochlea. A depth marker on the electrode array indicates complete insertion. The leading section is detached from the electrode array and the electrode array is placed in tension by gently pulling both ends, which tension causes the electrode array to hug the modiolar wall of the cochlea. Wedges may be inserted at both cochleostomies to maintain the electrode array in tension.
