Abstract
A tip member for inserting into the cochlea, a device comprising: an elongate member including at least one electrode mounted thereon; and a tip member extending distally from a distal end of the elongate member, the tip member comprising a tapered portion tapering distally and a blunt end portion at a distal end of the tapered portion, wherein the tip member is resiliently flexible, and a method for making such a device.
Claims22
An intra-cochlea electrode array comprising:
- an elongate carrier member;
- a plurality of electrodes spaced along the carrier member;
- and
- a flexible tip member disposed adjacent a distal end of the carrier member,
- wherein the tip member extends distally from the distal end of the carrier member, and wherein the tip member tapers distally, and
- wherein the flexible tip member comprises a blunt distal end, and wherein the tip member is substantially frusto-conical in shape.
3 more elements
An intra-cochlea electrode array comprising:
- an elongate carrier member having an axis and a first taper along the axis;
- a plurality of electrodes spaced along the carrier member;
- and
- a flexible tip member disposed proximate an end of the carrier member, wherein the tip member has a second taper greater than the first taper.
1 more element
A cochlear implant, comprising:
- an intra-cochlea electrode array including a plurality of electrodes configured to stimulate tissue of a recipient of the cochlear implant, an electrode carrier section carrying the electrodes and a tip section, wherein the tip section is flexible and disposed adjacent a distal end of the carrier section, wherein
- the electrodes of the electrode array are spaced along the carrier section in a longitudinal direction of the array, and
- the tip section includes a proximal end disposed proximate the distal end of the carrier section, a part-spherical blunt end disposed opposite the proximal end and a continuous tapered portion between the proximal end and the part-spherical blunt end.
