Abstract
In an embodiment, a lead system includes a cuff electrode to secure to a nerve, a first lead portion defining a longitudinal axis, and a second lead portion. An anchor may be between the first lead portion and the second lead portion to secure to non-nerve structure. A connector may extend from the second lead portion to connect to a pulse generator. Electrode elements are spaced apart along the cuff body. The cuff electrode may include a first resilient arcuate-shaped portion extending in a first circumferential direction and having a first arc length; and a second resilient arcuate-shaped portion integrally formed with the first arcuate-shaped portion, extending in a second circumferential direction, and having a second arm length greater that the first arc length. The second arcuate-shaped portion overlaps the first arcuate-shaped portion, The first and second arcuate-shaped portions define a lumen having a substantially re-closable opening.
