摘要： An implantable drug-delivery sleeve for an elongate component of an implantable medical device. The sleeve includes a tubular substrate having a lumen configured to receive the elongate component so as to allow relative displacement of the substrate and the elongate component, wherein the substrate is shaped so as to be retained stationary at a desired position along the elongate component, and a drug releasably carried by the substrate.

摘要： A non-communicative lumen for electrode assemblies of medical implants, in particular prosthetic hearing implants, is provided by the present invention. The non-communicative lumen prevents the lumen within the cochlea from being able to transport fluids, cells, bacteria, tissue, etc., with the lumen outside the cochlea, and vis versa through the incision or cochleostomy. The lumen may have a cavity or slit that receives a stylet during insertion of the electrode assembly.

摘要： An implantable electrode array (30) that can adopt a first configuration selected to allow the array (30) to be inserted into a cochlea (12) of an implantee and at least a second configuration in which the array can apply tissue stimulation. The array (30) comprises an elongate carrier (31) having a proximal end (37), a distal end (34), and an inner surface (35) conformable with the inner wall of the implantee's cochlea (12). A plurality of electrodes (36) are supported within the carrier (31) at respective spaced locations thereon in a region between the proximal end (37) and the distal end (34) with at least one of the electrodes having a surface that is at least adjacent the inner surface (35) of the carrier (31). The carrier (31) is formed in the second configuration from a first layer (32) and at least a second layer (32) of resiliently flexible material. A method of forming an array (30) is also described.

摘要： An electrode for a cochlear implant for implantation in a cochlea of a patient, the electrode having a first side that is curved in a lateral dimension so as to substantially conform to a side wall of a scala upon implantation of the electrode into a cochlea and a second side that is shaped so as to preserve a natural acoustic pathway within the scala upon implantation of the electrode into the cochlea. In one example, opposing ends of the electrode taper off in cross section. In another example, the fluid contact side is concave. In a further example, the electrode is one of crescent-shaped, oval shaped, and semi-circular in cross section. By using such an electrode, a more natural fluid-flow in the cochlea can be maintained after implantation relative to an original fluid-flow prior to implantation.

摘要： A cochlear implant electrode assembly device (10) comprising an elongate electrode carrier member (11), a stiffening element (15), and a stiffening sheath (16) that at least partially envelops the elongate member (11). The member (11) is made of a resiliently flexible first material and has a plurality of electrodes (12) mounted thereon. The member (11) has a first configuration that allows it to be inserted into an implantee's cochlea (30). The member (11) also has a second configuration wherein the member is curved to match an inside surface of the cochlea (30), and at least one intermediate configuration between the first and second configurations. Both the stiffening element (15) and sheath (16) are made of a material that is relatively stiffer than the member (11). The stiffening element (15) and the stiffening sheath (16) in combination bias the elongate member (11) into the first configuration. If either the stiffening element (15) or the stiffening sheath (16) is removed or deactivated, the elongate member (11) adopts an intermediate configuration.
