ELECTRODE LEAD SYSTEM
First Claim
Patent Images
1. A lead system comprising:
- a cuff electrode;
a first lead portion extending from the cuff electrode and having a generally serpentine configuration;
a second lead portion having a generally serpentine configuration and having a length substantially greater than a length of the first lead portion;
a first anchor interposed between the first lead portion and the second lead portion and configured to be secured relative to a non-nerve body structure; and
a connector extending proximally from the second lead portion and configured to electrically connect to an implantable pulse generator,wherein the first lead portion has a length substantially greater than a distance between a nerve, onto which the cuff electrode is attached, and the non-nerve body structure onto which the first anchor is secured such that at least a portion of the first lead portion retains the generally serpentine configuration.

10. A method of delivering a lead assembly to treat sleep apnea, the method comprising:
-
providing a lead assembly including a cuff electrode, a first lead portion with a generally serpentine configuration, an anchor, a second lead portion with a generally serpentine configuration, and a connector, wherein a length of the first lead portion is substantially greater than a distance between a hypoglossal nerve and a non-nerve bodily structure adjacent the nerve; releasably securing the cuff electrode about the hypoglossal nerve; maneuvering and arranging the first lead portion to extend proximally from the cuff electrode toward the non-nerve bodily structure; securing the anchor to the non-nerve bodily structure adjacent the target nerve while maintaining at least a portion of the first lead portion in a generally serpentine configuration as the first lead portion extends between the cuff electrode and the anchor; and maneuvering and arranging the second lead portion to extend proximally from the anchor toward an implantable pulse generator. - View Dependent Claims (11, 12, 13, 14)
