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.

A cochlear implant (300) includes a processor (185), an array (195) of electrodes disposed along a flexible body and a lead body (192) connecting the processor to the array of electrodes. The lead body includes a first tube (435) having a first outside diameter, a second tube (445) having a second outside diameter smaller than the first diameter, a portion of the second tube being disposed within the first tube, and wires (420,430) passing through the first tube and the second tube, the wires comprising a helically coiled portion. A method for forming a lead body is also provided.

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 retractor assembly disposed at least partially within the handle assembly, and a slider assembly disposed at least partially within the handle assembly. The retractor assembly may include a stiffening member configured to be inserted into an electrode array portion and a spring-loaded retractor member coupled to the stiffening member and 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 slider assembly may be configured to selectively retain the spring-loaded retractor member and further configured to release the spring-loaded retractor member to move from the distal position to the proximal position in response to actuation by a user of the slider assembly.
摘要:
A device includes a hermetically sealed case with electronic circuitry housed within. One surface of the hermetically sealed case includes a metallic plate and a co-fired ceramic electrical feedthrough with a number of vias. The co-fired ceramic electrical feedthrough is hermetically joined to the metallic plate and a hybrid circuit is connected to the feedthrough.
