Push-in suture anchor system

Abstract

Improved suture anchor systems and methods of use are disclosed herein. The suture anchor may have proximal and distal ends, and first and second lateral sides extending between the proximal end and the distal end. A centrally located suture passage may extend through the anchor body from a first opening in the first lateral side to a second opening in the second lateral side. A channel may extend along a longitudinal axis of the anchor body. The insert may be configured to translate longitudinally within the channel between the proximal end of the anchor body and the distal surface of the suture passage. There may also be provided a surgical broach adapted for use with the suture anchor system.

         14 . The suture anchor system of  claim 13 , wherein insert body is configured to clamp the one or more sutures to the distal surface of the suture passage. 
     
     
         15 . A suture anchor kit comprising:
 a. a suture anchor comprising:
 i. an anchor body having a proximal end, a distal end, a longitudinal axis, a first lateral side extending between the proximal and distal end, and a second lateral side extending between the proximal and distal end; 
 ii. a suture passage comprising a proximal surface and a distal surface and extending through the anchor body from a first opening in the first lateral side to a second opening in the second lateral side, 
 iii. a plurality of distal ridges disposed on the anchor body, wherein the plurality of distal ridges is proximal to the distal end and distal to the suture passage; 
 iv. one or more proximal ridges disposed on the anchor body, wherein the one or more proximal ridges are distal to the proximal end and proximal to the suture passage; 
 v. a channel defined within the anchor body and extending along the longitudinal axis of the anchor body from a proximal opening in the proximal end of the anchor body to an opening in the proximal surface of the suture passage, and
