Graft fixation device combination

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.

I claim:  
     
         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.
