Abstract
Abstract An implant for the treatment of the pain of arthritis which comprises a carbon fiber which has a discontinuous coating of gold thereon, exposing the carbon in patches. The carbon and gold form a galvanic couple which is implanted in an arthritic joint and in the presence of body fluids acts like a battery and released gold ions continuously, thus relieving pain.

Claims Analysis
Total Claims: 4
Claim 1
Independent Claim
65 words
A joint implant for the continuous production of gold ions to treat the pain of arthritis comprising, a core element comprising a carbon fiber, a discontinuous coating of gold on said carbon fiber exposing the carbon in patches, the carbon fiber and gold forming a galvanic couple which in the presence of body fluids continuously release gold ions to treat the pain of the arthritis.
Claim 2
Dependent Claim
65 words
A joint implant for the continuous production of gold ions to treat the pain of arthritis comprising, a core element comprising a carbon fiber, a discontinuous coating of gold on said carbon fiber exposing the carbon in patches, the carbon fiber and gold forming a galvanic couple which in the presence of body fluids continuously release gold ions to treat the pain of the arthritis.
Claim 3
Independent Claim
73 words
A method of continuously treating arthritis comprising, providing a core element comprising a carbon fiber, coating said carbon fiber in a discontinuous manner with gold such that the carbon fiber is exposed in patches, permanently implanting the thus coated carbon fiber within an arthritic joint, whereby the gold and carbon fiber form a galvanic couple and in the presence of body fluids continuously release gold ions for relieving the pain of the arthritis.
Claim 4
Independent Claim
