Patent ID: 8639354

Claim:
A lead system comprising: a cuff electrode configured to be secured to a nerve of a patient; a first lead portion extending from the cuff electrode and having a distal end coupled to the cuff electrode, the first lead portion including a first flexible undulation disposed proximally of the distal end; a second lead portion having a second flexible undulation, wherein an entirety of the second flexible undulation is disposed proximally of an entirety of the first flexible undulation; an 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 cuff electrode comprises: a first resilient arcuate-shaped portion extending in a first circumferential direction away from a longitudinal axis of the first lead portion and having a first arc length in the first circumferential direction when secured to the nerve, wherein a substantial entirety of the first resilient arcuate-shaped portion defines a first substantially constant cross-sectional dimension; and a second resilient arcuate-shaped portion integrally formed of a one-piece construction with the first resilient arcuate-shaped portion, extending in a second circumferential direction away from the longitudinal axis of the first lead portion opposite the first circumferential direction, and having a second arc length in the second circumferential direction when secured to the nerve, wherein the second arc length is greater than the first arc length, wherein the second resilient arcuate-shaped portion overlaps the first resilient arcuate-shaped portion, wherein the first and second resilient arcuate-shaped portions define a lumen having a substantially re-closable opening, wherein the lumen includes an inner surface that transitions seamlessly from the first resilient arcuate-shaped portion to the second resilient arcuate-shaped portion, wherein the inner surface includes at least one electrode disposed therein, wherein a substantial entirety of the second resilient arcuate-shaped portion defines a second substantially constant cross-sectional dimension, and wherein the first substantially constant cross-sectional dimension is equal to the second substantially constant cross-sectional dimension.
