Methods and collagen products for tissue repair

Abstract

Methods and devices for the repair of articular tissue using collagen material are provided. Compositions of collagen material and related kits are also provided.

We claim: 
     
         1 . A tissue healing device configured to repair a ligament, comprising:
 a. a hydrophilic scaffold that is compressible and expandable, the scaffold configured to be positioned between a ruptured end of the ligament and a bone;   b. at least one anchor configured to be secured to the bone;   c. at least one suture configured to be threaded through or along the scaffold to position the scaffold between to the ruptured end of the ligament and the bone; and   d. one or more growth factors configured to be disposed within or on the scaffold.   
     
     
         2 . The tissue healing device of  claim 1 , wherein the scaffold includes collagen. 
     
     
         3 . The tissue healing device of  claim 2 , wherein the collagen is a type I collagen. 
     
     
         4 . The tissue healing device of  claim 3 , wherein a concentration of collagen in the scaffold is at least 15 mg/ml. 
     
     
         5 . The tissue healing device of  claim 1 , wherein the scaffold is configured to carry a repair material. 
     
     
         6 . The tissue healing device of  claim 5 , wherein the repair material includes platelets. 
     
     
         7 . The tissue healing device of  claim 5 , wherein the repair material includes plasma. 
     
     
         8 . The tissue healing device of  claim 5 , wherein the repair material includes white blood cells. 
     
     
         9 . The tissue healing device of  claim 1 , wherein the at least one anchor is a first anchor, the at least one suture is a first suture and the bone is a first bone such that the first suture is configured to be secured to the first anchor, wherein the device further comprises:
 a second suture configured to secure the ligament in place relative to the first bone and a second bone; and   a second anchor for contact with the second bone such that the second anchor is configured to secure the second suture to the second bone.   
     
     
         10 . The tissue healing device of  claim 9 , wherein the first bone is a femur and the second bone is a tibia. 
     
     
         11 . The tissue healing device of  claim 9 , wherein at least one of first anchor and the second anchor is an endobutton. 
     
     
         12 . The tissue healing device of  claim 9 , wherein the scaffold includes collagen and a concentration of collagen in the scaffold is at least 15 mg/ml.
