Abstract

A graft fixation device combination. The device is useful for affixing a tissue graft to a bone or other body surface. The fixation device has two implantation members connected by a graft retention member. The retention member optionally has at least one lateral wing member extending therefrom. The implantation members have longitudinal passageways therethrough. The graft fixation device also has an insertion member extending from the distal end of each implantation member, the insertion member having a longitudinal passage having a distal blind wall. The passages of the implantation members and the insertion members are in communication with each other, and may be mounted onto insertion members.

Claims

1. A graft fixation device, comprising:

a first implantation member, said implantation member having a longitudinal axis, a proximal end, a distal end, an outer surface, a longitudinal passage therethrough, a proximal opening and a distal opening, wherein both openings are in communication with the passage;

a retention member connecting the first and second implantation members, the retention member having a central section, a first end section extending from the first implantation member and a second end section extending from the second implantation member; and

,

an insertion member extending from the distal end of each implantation member, wherein the insertion member has a proximal end, a distal end, a proximal opening, a and outer surface and a longitudinal passage in communication with the proximal opening, wherein said longitudinal passage has a distal blind end, and wherein the longitudinal passage of each insertion member is in communication with the longitudinal passage of the respective implantation members.

2. The device of claim 1 additionally comprising at least one wing member extending from the retention member.

3. The device of claim 1, wherein the implantation members have a series of ridges extending from the outer surfaces thereof.

4. The device of claim 1, wherein the retention member comprises a semicircular configuration.

5. The device of claim 1, wherein the implantation members have a substantially cylindrical configuration.

6. The device of claim 1 wherein the insertion member comprises a bioabsorbable material selected from the group consisting of polylactic acid, polyglycolic acid, tricalcium phosphate, calcium phosphate, tetracalcium phosphate and hydroxyapatite, and copolymers, mixtures and blends thereof.

7. The device of claim 1 wherein the insertion member comprises a biocompatible material selected from the group consisting of titanium, stainless steel, ceramic, polysulfone, acetal, and Nitinol.

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

9. The device of claim 1 wherein the fixation device comprises two opposed wing members extending from the retention member.

10. The device of claim 1 wherein the implantation members comprise a cylindrical shape having a distally extending frustoconical end.
