摘要： An implantable electrode is described for a cochlear implant patient with a cochlea having a single internal cavity defined by an outer cavity wall. The electrode includes an extra-cochlear electrode lead with signal wires for conducting electrical stimulation signals. An intra-cochlear electrode array is configured to be inserted into the cochlea through a single cochleostomy opening and is made of a resilient carrier material having an outer surface with one or more stimulation contacts for delivering the electrical stimulation signals to adjacent neural tissue. An insertion line is attached to the outer surface of the electrode array at a distal end and is made of a line material different from the electrode carrier material. The insertion line is configured to have an extra-cochlear end extending outside the cochleostomy opening during surgical insertion of the electrode array into the cochlea.

摘要： A cochlear implant electrode includes an implantable array carrier made of flexible material with electrode contacts distributed on its outer surface along a longitudinal axis. Electrode wires are embedded within the array carrier, each electrode wire having a terminal end electrically connected to a corresponding electrode contact for applying electrical stimulation signals carried by the electrode wires to adjacent neural tissue within the cochlea. Each electrode wire has an inner non-crystal conductive material surrounded by a flexible outer seal. The flexible material of the array carrier is configured to be reactive with the non-crystal conductive material of the electrode wires so that if a break occurs in the outer seal of an electrode wire that allows contact between the flexible material and the non-crystal conductive material, then a local leakage seal will form at the break that resists migration of the non-crystal conductive material to the outer surface of the array carrier.

摘要： An implantable electrode arrangement for a cochlear implant system is described that prevents post-surgical retraction of the electrode. The arrangement includes at least one retraction limiter having an extracochlear portion located at a distal end of the extracochlear electrode lead and an intracochlear portion located at a proximal end of the intracochlear electrode array and made at least in part of a swellable material that expands in response to fluid contact. The intracochlear portion of the retraction limiter is adapted for deformation away from an outer surface of the array proximal end in response to exposure of the swellable material to perilymph fluid within the cochlea after surgical insertion of the electrode array into the implanted cochlea so as to form an anti-retraction projection preventing post-surgical retraction of the array proximal end back through the electrode opening in the outer surface of the implanted cochlea.

摘要： An implantable electrode is described for a cochlear implant patient with a malformed common cavity cochlea having a single internal cavity defined by an outer cavity wall or patients having an incomplete partition or conventional spiral-shaped cochlea. An intra-cochlear electrode array is configured to be inserted into the cochlea through a single cochleostomy opening. Outer array branches are closable about a center axis and the electrode array is configured to be closed into a single tube including the array branches for insertion through the single cochleostomy opening into the internal chamber of the cochlea. The electrode array opens within the internal cavity after insertion into the cochlea so that the array branches move away from the center axis to lie with their outer surfaces against the outer cavity wall to deliver the electrical stimulation signals through the stimulation contacts to adjacent neural tissue for auditory perception by the patient.

摘要： An implantable medical device includes an implantable coil case that contains a communications coil. A magnet receptacle is located within the coil case at the radial center and has a magnet opening in one of the lateral surface or the medial surface of the coil case. A magnet fitting groove is recessed into one of the lateral or medial surface of the coil case and extends from the magnet opening to the outer circumference of the coil case. A u-shaped implant magnet clip has parallel clip legs that are connected at a closed end of the u-shape, and an implant magnet is attached to one of the clip legs. The coil case and the magnet clip are configured to cooperate for a portion of the coil case to fit between the clip legs and the implant magnet to slide through the magnet fitting groove and fit through the magnet opening into the magnet receptacle.

摘要： A cochlear implant electrode arrangement is described that prevents post-surgical retraction of the electrode array from the cochlea. The arrangement includes an electrode lead that carries cochlear stimulation signals from an implanted signal processor, through an oval shaped posterior tympanotomy opening in the facial recess of a patient, to an electrode array implanted in a cochlea of the patient. A retraction limiter slides over the electrode lead through the posterior tympanotomy with projection arms aligned along the long diameter of the posterior tympanotomy, then is rotated to align the projection arms along the short diameter of the posterior tympanotomy, and secured to the electrode lead so that the projection arms prevent post-surgical retraction of the electrode lead back through the posterior tympanotomy.

摘要： A bilateral hearing implant surgical template arrangement is described. An implant fits behind the outer ear pinna of a recipient patient and conforms against an underlying side of the head. The implant stimulator template has an implant outline defining an area corresponding to an implanted stimulator of the bilateral hearing implant system, and has an adjustable connection that allows adjustment of the position of the implant stimulator template with respect to the outer ear pinna so as to define stimulator implantation sites at symmetric locations on each side of the patient's head. A behind the ear (BTE) processor template also has a processor outline defining an area corresponding to an external BTE processor device of the bilateral hearing implant system and fits behind the ear pinna at the adjustable connection with the implant stimulator template, and conforms against an underlying side of the patient's head.
