Threaded suture anchor

Abstract

The present disclosure relates to a suture anchor. The suture anchor includes a body having a proximal end and a distal end, the body including threads along at least a partial length of the body and at least one through hole, the threads including a profile such that the threads located near the distal end of the body include a first shape and the threads located near the proximal end of the body include a second shape different from the first shape. Delivery devices and anchor dilators are also disclosed.

1 - 6 . (canceled) 
     
     
         7 . An assembly comprising:
 an inserter comprising an elongate shaft having a proximal end, a distal end, and a longitudinal cannulation extending between the proximal end and the distal end, a size and shape of the distal end of the shaft being different than a size and shape of the proximal end of the shaft;   an anchor comprising:
 an anchor body including a proximal end, a distal end, and a longitudinal axis extending between the proximal and distal ends, the anchor body including threads extending along at least a partial length of the body such that a portion of the distal end is not threaded, the body defining a cannulation extending from the proximal end of the anchor body configured to receive the distal end of the shaft; 
 at least one through hole oriented transverse to the longitudinal axis of the body and intersecting the cannulation of the anchor body; and 
 a suture bridge formed within the anchor body distal to the at least one through hole; and 
   a flexible member extending around a distal end of the suture bridge and through the cannulation of the anchor body;   wherein the size and shape of the distal end of the shaft corresponds to a size and shape of the cannulation of the anchor body to allow for torque to be applied to the anchor when the anchor is inserted into bone.   
     
     
         8 . The assembly of  claim 7 , wherein the distal end of the shaft includes at least one projection for mating with at least one recess in the anchor body. 
     
     
         9 . The assembly of  claim 7 , wherein the threads extend from the proximal end of the anchor body to at least an area adjacent the at least one through hole. 
     
     
         10 . The assembly of  claim 7 , wherein the at least one through hole comprises a first through hole and a second through hole, and the suture bridge extends between the first through hole and the second through hole. 
     
     
         11 . The assembly of  claim 7 , wherein when the flexible member extends through the cannulation of the shaft of the inserter and exits a proximal end of the shaft. 
     
     
         12 . The assembly of  claim 7 , wherein the body of the anchor is tapered from the proximal end to the distal end. 
     
     
         13 . The assembly of  claim 7 , wherein a profile of the threads at the distal end of the anchor body are different than a profile of the threads at the proximal end of the anchor body. 
     
     
         14 . The assembly of  claim 7 , wherein the anchor body comprises a non-metal material. 
     
     
         15 . The assembly of  claim 7 , wherein the inserter comprises a metal material. 
     
     
         16 . The assembly of  claim 7 , wherein the flexible member is a suture.
