Abstract
An implantable electrode assembly for gripping nerves or other bodily structures is disclosed. The assembly comprises first and second spines containing first and second leads with at least one electrode cross rail joining the spines and at least one electrode providing a route for electrical conduction between the first and second lead. Mating structures on the spines allow the spines to be joined for securely attaching the assembly around the nerve.
