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.
