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 connecting member has at least one lateral wing member extending therefrom. 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 method of mounting a matrix to tissue, comprising the steps of:

providing a graft fixation device comprising the combination of;

I. A fixation device comprising;

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

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

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

,

at least one wing member extending laterally from the connecting member; and

,

II. A pair of insertion members each insertion member, comprising;

a member having a proximal end, a distal tapered end and a longitudinal passage therethrough,

wherein the distal end of each implantation member is in engagement with the proximal end of an insertion member;

mounting the combination to an insertion instrument having a pair of spaced apart prongs, said prongs having distal ends and distal tips extending therefrom, such that the prongs are contained within the passages of the implantation members, such that the distal tips of the prongs extend beyond the distal ends of the insertion members;

placing a matrix onto the surface of the bone; and

,

inserting the implantation members and insertion members through the matrix and into the bone thereby forming bore holes while simultaneously emplacing the implantation members in the bone, thereby securing the matrix to the bone.

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

3. The method of claim 1, wherein the connecting member comprises a configuration having a central section and rod members, wherein the rod members are substantially parallel to the longitudinal axes of the implantation members, and the central section is substantially perpendicular to the rod members.

4. The method of claim 1, wherein the connecting member has a semi-circular configuration.

5. The method of claim 1, additionally comprising a frustoconical end extending from the distal end of the first implantation member and the distal end of the second implantation member.

6. The method of claim 1, wherein the implantation members have a cylindrical configuration.

7. The method 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.

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

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

10. The method of claim 1 wherein the fixation device comprises two opposed wing members extending from the connecting member.

11. The device of claim 1 wherein the insertion members comprise a cylindrical shape having a distally extending frustoconical tip.

12. A method of mounting a matrix to tissue, comprising the steps of:

providing a fixation device comprising;

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

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

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

,

at least one wing member extending laterally from the connecting member;

mounting the device to an insertion instrument having a pair of spaced apart prongs, said prongs having distal ends and distal tips extending therefrom, such that the prongs are contained within the passages of the implantation members;

placing a matrix onto the surface of the bone;

forming a pair of bore holes in the bone; and

,

and inserting the implantation members through the matrix and into the bone bore, thereby securing the matrix to the bone.

13. The method of claim 12, wherein the implantation members have a series of ridges extending from the outer surfaces thereof.

14. The method of claim 12, wherein the connecting member comprises a configuration having a central section and rod members, wherein the rod members are substantially parallel to the longitudinal axes of the implantation members, and the central section is substantially perpendicular to the rod members.

15. The method of claim 12, wherein the connecting member has a semi-circular configuration.

16. The method of claim 12, additionally comprising a frustoconical end extending from the distal end of the first implantation member and the distal end of the second implantation member.

17. The method of claim 12, wherein the implantation members have a cylindrical configuration.

18. The method of claim 12 wherein the fixation device comprises a bioabsorbable polymer.

19. The method of claim 12 wherein the fixation device comprises two opposed wing members extending from the connecting member.
