摘要:
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.
摘要:
In one example, a cochlear lead includes a flexible body, an array of electrodes in the flexible body, and a plurality of wires passing along the array of electrodes. The plurality of wires includes a flexural geometry between each pair of adjacent electrodes and a substantially straight geometry over the electrodes. A method for forming an electrode array with a reduced apical cross section is also provided.
