Abstract
Abstract A fastener for fastening a muscle tendon and muscle to a bone. The fastener has a shank designed to be inserted through a tendon and into a channel bored through a bone. A fastening head terminates the shank and is designed to come into abutment against the muscle and muscle tendon to hold the muscle and uscle tendon against the bone. A locking member is designed to cooperate with the shank at the distal end of the shank that emerges from a tunnel in bone in order to lock the shank end fastening head relative to the bone and to the muscletendon and muscle.

Claims Analysis
Total Claims: 9
Claim 1
Independent Claim
153 words
A fastener for fastening a muscle tendon to a bone, said fastener comprising: a shank designed to be inserted through the tendon and through the channel bored through a bone, said shank having a proximal end and a distal end; a fastening head mounted to the proximal end of said shank such that the head is capable of swivel movement, said head having a hemispherical cavity wherein said shank is designed to come into abutment against the muscle to hold it against the bone; and a locking member designed to co-operate with the shank at the distal end thereof that emerges from the tunnel through the bone to lock said shank and its head relative to the bone and to the muscle, wherein the proximal end of the shank is terminated by a ball on which the fastening head is swivel-mounted by mating the ball with the hemispherical cavity of the fastening head.
Claim 2
Dependent Claim
153 words
A fastener for fastening a muscle tendon to a bone, said fastener comprising: a shank designed to be inserted through the tendon and through the channel bored through a bone, said shank having a proximal end and a distal end; a fastening head mounted to the proximal end of said shank such that the head is capable of swivel movement, said head having a hemispherical cavity wherein said shank is designed to come into abutment against the muscle to hold it against the bone; and a locking member designed to co-operate with the shank at the distal end thereof that emerges from the tunnel through the bone to lock said shank and its head relative to the bone and to the muscle, wherein the proximal end of the shank is terminated by a ball on which the fastening head is swivel-mounted by mating the ball with the hemispherical cavity of the fastening head.
Claim 3
Dependent Claim
32 words
A fastener according to claim 1, wherein, to co-operate with the locking member, the shank is provided with a plurality of serrations distributed uniformly over at least a portion of its length.
Claim 4
Dependent Claim
23 words
A fastener according to claim 2, wherein the shank is provided with a plurality of serrated zones disposed in alternation with smooth zones.
Claim 5
Dependent Claim
44 words
A fastener according to claim 1, where in the locking member is a tube which is substantially frustoconical externally, and which is designed to be fastened to the bone by means of its frustoconical wall being clamped in the channel bored through the bone.
Claim 6
Dependent Claim
79 words
A fastener according to claim 4, wherein to co-operate with the locking member, the shank is provided with a plurality of serrations distributed uniformly over at least a portion of its length, and wherein the locking member is provided with a plurality of internal serrations designed to co-operate with the serrations carried by the shank to enable the locking member to slide along the shank in one direction, and to prevent it from sliding therealong in the other direction.
Claim 7
Dependent Claim
20 words
A fastener according to claim 5, wherein the locking member is provided with annual recesses level with the internal serrations.
