    摘要： A method for forming a cochlear electrode array with a plurality of electrodes which are spaced so as to stimulate sites within a cochlea includes shaping a sheet of electrically conductive material to form a support structure and a plurality of electrodes, in which the electrodes are tethered to the support structure at the spacing of the cochlear electrode array. A cochlear lead includes a flexible body that has frictional characteristics that vary about its circumference. A cochlear lead includes a flexible body with a first region and a second region with different surface textures. This generates differential sliding forces during insertion of the cochlear lead which influence a motion of the cochlear lead during insertion. The cochlear lead having an electrode array with varying stiffness along its length is also provided.

    摘要： Exemplary insertion tools, systems, and methods for inserting an electrode array portion of a lead into a bodily orifice are described herein. An exemplary insertion tool includes a handle assembly, a slider assembly, a retractor assembly disposed at least partially within the handle assembly, and a rocker lever. The retractor assembly may include a stiffening member configured to be inserted into the electrode array portion and a spring-loaded retractor member coupled at a proximal end of the stiffening member. The spring-loaded retractor member may be configured to move from a distal position to a proximal position to at least partially retract the stiffening member from the electrode array portion. The rocker lever may be configured to selectively retain the spring-loaded retractor member in the distal position. Corresponding tools, systems, and methods are also described.

    摘要： Exemplary insertion tools, systems, and methods for inserting a pre-curved electrode array portion of a lead into a bodily orifice are described herein. An exemplary insertion tool includes a handle assembly, a slider assembly, an insertion assembly coupled to the handle assembly, and a retractor assembly disposed at least partially within the handle assembly and configured to selectively couple to a straightening member inserted into the pre-curved electrode array portion and at least partially retract the straightening member from the pre-curved electrode array portion in response to actuation by a user of the slider assembly. The retractor assembly may comprise a spring-loaded retractor member configured to move from a distal position to a proximal position in response to actuation by the user of the slider assembly to at least partially retract the straightening member from the pre-curved electrode array portion. Corresponding insertion tools, systems, and methods are also described.
