1. A stimulator arrangement for a nerve in a body of a patient, comprising:
- an electrode arrangement havinga substrate comprising an inner surface, the substrate comprising an arched portion and at least one relatively-flat stabilizing portion extending from, and abutting, each side of two opposing sides of the arched portion, wherein the inner surface of the arched portion is configured and arranged to receive the nerve upon implantation, wherein the arched portion is formed from a material configured and arranged to flatten the arched portion in response to exposure to the body after implantation such that the inner surface of the arched portion at least partially flattens the nerve, anda plurality of electrodes disposed on the inner surface of the substrate.

Abstract
A stimulator arrangement for stimulating nerves or other tissue includes an electrode arrangement having a substrate and a plurality of electrodes disposed on the substrate. The substrate is configured and arranged to be in a curved state prior to implantation into the body and to flatten with exposure to the body after implantation. The stimulator arrangement may also include a stimulator unit coupled to the electrode arrangement. The stimulator unit may also be implantable.
