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.

1. A microcircuit integrated cochlear electrode array having a longitudinal axis, comprising:
a flat multi-conductor tail portion having spaced electrode receiving pads on an exposed surface thereof and helically wrapped about the longitudinal axis; and ring electrodes carried by the helically wrapped tail portion, extending around the longitudinal axis and electrically connected to the electrode receiving pads on an electrode section of the helically wrapped tail portion, wherein a portion of the tail portion is unwrapped to define a lateral offset spaced from the longitudinal axis of the electrode section.
