Implantable tissue growth stimulator
First Claim
1. A bone growth stimulator for use with an orthopaedic device including an acetabular cup with a hemispherical exterior surface, the bone growth simulator comprising:
- a plurality of electrical conductors arranged in a preformed geometry and adapted to provide electrical stimulation to a bone; and
a sheath comprising a hemispherical configuration and having a first surface for engaging the exterior surface and a second surface for engaging the bone, the sheath adapted for at least partially maintaining the geometry of the plurality of electrical conductors, the plurality of electrical connectors each extending radially from a common point.

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 he controlled from an external device via wireless communication. The implantable tissue growth stimulator may be configured for use with an implants in particular, the implantable tissue growth stimulator may be incorporated into an orthopedic device such as a hip prosthesis. The implantable tissue growth stimulator may be used to stimulate bone growth.
