Multiple-pronged implantable stimulator and methods of making and using such a stimulator

摘要

An implantable stimulator includes a base, two prongs extending from the base and an electrode disposed on each of the prongs. This stimulator may be part of a system that includes an external device for transcutaneously communicating with the implanted stimulator. A method of using the implantable stimulator includes generating a current gradient between the electrodes on the two prongs to stimulate a target site in a patient. A method of making the implantable stimulator includes coating electrode material on the prongs except where the electrode surfaces are to be formed.
