Claims Analysis
Total Claims: 15
Claim 1
Independent Claim
43 words
A prosthesis which comprises artificial fibrous connective tissue and, at a distal end of said tissue, a bone implant comprising a tapered porous plug, said plug being connected to said artificial tissue with said plug tapering in the direction towards said artificial tissue.
Claim 2
Dependent Claim
43 words
A prosthesis which comprises artificial fibrous connective tissue and, at a distal end of said tissue, a bone implant comprising a tapered porous plug, said plug being connected to said artificial tissue with said plug tapering in the direction towards said artificial tissue.
Claim 3
Dependent Claim
38 words
A prosthesis according to claim 1 wherein the plug is provided with a passageway to receive an end of the fibrous connective tissue, means being provided to anchor the end of the fibrous connective tissue to the plug.
Claim 4
Dependent Claim
13 words
A prosthesis according to claim 2 wherein the anchor means comprises a pin.
Claim 5
Dependent Claim
27 words
A prosthesis according to claim 3 wherein the plug is provided with a recess extending across one face thereof, transversely of the passageway, for receiving the pin.
Claim 6
Dependent Claim
13 words
A prosthesis according to claim 1 wherein the plug is of frusto-conical shape.
Claim 7
Dependent Claim
13 words
A prosthesis according to claim 1 wherein the plug is of sintered metal.
Claim 8
Dependent Claim
39 words
A prosthesis according to claim 1 wherein said artificial tissue comprises a cord member, the central portion of the cord member being sheathed or coated with a material to promote sliding movement of the cord member within the body.
Claim 9
Dependent Claim
20 words
A prosthesis according to claim 1 wherein said plug is in the form of an elongated triangular cross sectional member.
Claim 10
Independent Claim
83 words
A method of attaching fibrous connective tissue, either artificial or natural, to bone, which comprises, not necessarily in the following sequence, providing a tapered porous plug, providing a resection in the bone to receive the plug snugly, inserting the plug into the resection, and anchoring the fibrous connective tissue to the plug with the taper of said plug extending in the direction of said tissue so that, in use, the fibrous connective tissue pulls on the plug in the direction of the taper.
Claim 11
Independent Claim
83 words
A method of attaching fibrous connective tissue, either artificial or natural, to bone, which comprises, not necessarily in the following sequence, providing a tapered porous plug, providing a resection in the bone to receive the plug snugly, inserting the plug into the resection, and anchoring the fibrous connective tissue to the plug with the taper of said plug extending in the direction of said tissue so that, in use, the fibrous connective tissue pulls on the plug in the direction of the taper.
Claim 12
Dependent Claim
47 words
A method according to claim 9, wherein the plug is of sintered metal and of frusto-conical shape having an axial passageway therethrough, the fibrous connective tissue being passed through the passageway and being anchored to the plug by means of a pin disposed transversely of said passageway.
Claim 13
Dependent Claim
76 words
A bone implant for attaching artificial fibrous connective tissue to bone, which implant comprises a tapered porous plug having remote ends including a large end and being provided with a passageway disposed in the direction of said taper between said ends to receive an end of fibrous connective tissue, and pin means for extending transverse to said passageway in bridging relation thereto at said enlarged end to anchor a fibrous connective tissue end to said plug.
Claim 14
Dependent Claim
76 words
A bone implant for attaching artificial fibrous connective tissue to bone, which implant comprises a tapered porous plug having remote ends including a large end and being provided with a passageway disposed in the direction of said taper between said ends to receive an end of fibrous connective tissue, and pin means for extending transverse to said passageway in bridging relation thereto at said enlarged end to anchor a fibrous connective tissue end to said plug.
Claim 15
Dependent Claim
28 words
A bone implant according to claim 11 wherein said plug is provided with a recess extending across said large end transversely of said passageway for receiving said pin.
