1. A method of providing bone growth stimulation within a body, comprising:
- providing an orthopaedic device comprised of at least two components such that the at least two components form a joint;
providing a bone growth stimulator separate from the orthopaedic device, the bone growth stimulator including a plurality of electrical conductors adapted to provide electrical stimulation to a bone and a malleable sheath having a first surface for engaging and conforming to one of the at least two components of the orthopaedic device and a second surface for engaging and conforming to the bone, the sheath adapted for at least partially maintaining the position of the plurality of electrical conductors;
inserting the bone growth stimulator into the body adjacent a bone;
operating the bone growth stimulator to provide electrical stimulation to the bone;
wherein providing the orthopaedic device includes;
providing a total hip joint prosthesis comprising an acetabular component and a femoral component, the acetabular component having a convex exterior surface and an opposing concave interior surface, the femoral component having a femoral head and a femoral stem; and
further comprising;
engaging the bone growth stimulator to the acetabular component prior to said inserting.

Abstract
An implantable tissue growth stimulator is disclosed. The implantable tissue growth stimulator includes electronic circuitry to alter the voltage output by the stimulator. The implantable tissue growth stimulator may be controlled from an external device via wireless communication. The implantable tissue growth stimulator may be configured for use with an implant. In particular, the implantable tissue growth stimulator may be incorporated into an orthopaedic device such as a hip prosthesis. The implantable tissue growth stimulator may be used to stimulate bone growth.
