Microcircuit cochlear electrode array and method of manufacture

摘要

A microcircuit integrated cochlear electrode array and a process for the manufacture thereof, the electrode array comprising a multiconductor tail portion with longitudinally spaced outwardly exposed electrode receiving pads and a flat multiconductor head portion connected to the tail portion and having spaced outwardly exposed circuit attachment pads, the tail and head portions being laminated between a nonconductive film substrate and an insulating cover and the tail portion being helically wrapped into a helix with the electrode receiving circuit attachment pads exposed and carrying ring electrodes overmolded with a suitable polymeric material.

主权项

1. A cochlear electrode array, comprising:
a tail portion comprising multiple elongated conductors wrapped together in a helix, said tail portion having spaced electrode receiving pads on an exposed surface thereof extending angularly from the conductors, wherein the electrode receiving pads are wider than the conductors; ring electrodes carried by the tail portion and electrically connected to the electrode receiving pads; and a lumen, wherein the tail portion is wrapped around the lumen, wherein the tail portion forms a spiral for cochlear implantation.
