STIMULATING BONE GROWTH AND CONTROLLING SPINAL CORD PAIN
First Claim
1. A method of stimulating bone growth for fusion promotion in a mammalian patient in need thereof which comprises:
- a. implanting an electro-conductive bone growth stimulating implant in a region in the patient where bone growth is desired;
b. providing outside the patient'"'"'s body a device that produces a direct current in the implant whereby bone growth is stimulated.

Abstract
Bone growth for fusion promotion is stimulated in a mammalian patient in need thereof. Bone growth stimulation is achieved by implanting an electro-conductive bone growth stimulating implant in a region in the patient where bone growth is desired. An external device is worn by the patient to produce a direct current in the implant whereby bone growth is stimulated. The external device produces a magnetic field that induces an electric current in the implant. The electric current stimulates bone growth. The implant contains strips of a biocompatible conductive metal, such as, for example, nickel, gold or titanium. The strips can also be made of a conductive polymer such as for example, graphene. Implants to treat spinal cord pain are also disclosed.
