Drug-delivery accessory for an implantable medical device
First Claim
Patent Images
1. An implantable medical device comprising:
- an elongate component that is at least partially implantable in a cochlear of a recipient; and
a drug-delivery sleeve releasably carrying at least one drug and having a lumen configured to receive the elongate component so as to allow relative displacement of the sleeve and the elongate component, wherein the sleeve is manually compressible to the elongate component such that the sleeve is retained stationary relative to the elongate component at an intra-cochlear region of the elongate component, wherein the sleeve includes an attachment frame having a length extending between first and second ends of the sleeve, and a plurality of rings each connected to the attachment frame, wherein the rings are aligned along the length of the attachment frame such that the elongate component is positionable in respective lumens of each of the rings concurrently, and wherein the attachment frame comprises a plurality of severable regions at which the rings may be severed from each other.

Abstract
An implantable drug-delivery sleeve for an elongate component of an implantable medical device. The sleeve includes a tubular substrate having a lumen configured to receive the elongate component so as to allow relative displacement of the substrate and the elongate component, wherein the substrate is shaped so as to be retained stationary at a desired position along the elongate component, and a drug releasably carried by the substrate.

11. An implantable medical device comprising:
-
an elongate tapered electrode carrier member that is implantable in a recipient; a tubular substrate having a lumen extending between first and second ends of the substrate, wherein the lumen is configured to receive the electrode carrier member so as to allow relative displacement of the substrate and the electrode carrier member, wherein the substrate is shaped so as to be retained stationary at a desired position along the electrode carrier member at an intra-cochlear region of the electrode carrier member, wherein the lumen has a first diameter at the first end and a second diameter at the second end that is smaller than the first diameter, and wherein the substrate is positioned on the electrode carrier member such that the first diameter of the lumen is disposed at the desired position and the second diameter of the lumen is disposed at a portion of the electrode carrier member having a diameter that is greater than or equal to the second diameter of the lumen, and wherein the diameter of the electrode carrier member at the desired position is greater than or equal to the diameter of the lumen at the desired position; and a drug releasably carried by the substrate. - View Dependent Claims (12, 13, 14, 15, 16, 17, 18, 19, 20, 21)
