Abstract
Abstract An anchor for a body stimulation lead. A first body member is provided with an aperture while a second body member has a post extending from a surface thereof into the first body member aperture. At least the proximal portion of the post is slightly larger than the aperture to establish a press fit therein. Grooves are provided within one of the body members and are adapted to accept a body stimulation lead of known generally circular cross section. In a preferred embodiment, the groove opening is no greater than the lead diameter and the groove depth is at least as great as the lead radius. Suture cooperating elements are provided to facilitate securement of the anchor to body tissue.
