Abstract

A graft fixation device combination. The device is useful for affixing a tissue graft to a bone or other body surface. The combination has a fixation device having two implantation members connected by a connecting member. The implantation members have longitudinal passageways therethrough. The combination also has an insertion member in engagement with the distal end of each implantation member.

Claims

1. A graft fixation device, comprising:

an implantation member, said implantation member having a longitudinal axis, a proximal end, a distal end, an outer surface, and a longitudinal passage therethrough;

at least one graft retention member, the retention member having a first section extending from the proximal end of the implantation member, and a second section angulated with respect to first section for engaging a graft.

2. The device of claim 1, wherein the implantation member has a series of ridges extending from the outer surface.

3. The device of claim 1, wherein the retention member comprises a rod member.

4. The device of claim 3, wherein the retention member has an oval cross-section.

5. The device of claim 1, additionally comprising a frustoconical insertion member extending from the distal end of the implantation member, said insertion member having a proximal end, a distal end and an axial passage therethrough.

6. The device of claim 1, wherein the implantation member has a cylindrical configuration.

7. The device of claim 5 wherein the insertion member comprises a bioabsorbable material selected from the group consisting of polylactic acid, polyglycolic acid, polycaprolactone, tricalcium phosphate, calcium phosphate, tetracalcium phosphate and hydroxyapatite, and copolymers, mixtures and blends thereof.

8. The device of claim 5 wherein the insertion member comprises a biocompatible material selected from the group consisting of titanium, stainless steel, ceramic, Delrin, and Nitinol.

9. The device of claim 1 wherein the fixation device comprises a bioabsorbable polymer.

10. The device of claim 1 comprising four retention members.

11. The device of claim 1 comprising two retention members.
