20110106154 | PARTIAL THICKNESS ROTATOR CUFF REPAIR SYSTEM AND METHOD - A suture anchor is disclosed which has an elongated body having a distal end, a proximal end and an exterior surface. An axially oriented bore extends into the body from the proximal end and a proximal portion of the bore has a plurality of abutment surfaces for engaging a tool. The bore includes one or more axially oriented suture passages leading to a suture attachment within the bore. A length of suture extends into the at least one suture passage from the body proximal end and extends to the suture attachment. A screw thread spirals about a portion of the exterior surface of the body adjacent the at least one suture passage. Between the bore and the exterior surface of the body the body has a wall thickness and wherein the suture passage comprises the area where the wall thickness goes to zero. | 05-05-2011 |
20110106013 | DUAL CANNULA SYSTEM AND METHOD FOR PARTIAL THICKNESS ROTATOR CUFF REPAIR - A method and system is provided for passing a suture anchor through a soft tissue and into a bone. The method includes the steps of locating a desired anchor receiving site on the bone; passing a locating wire through the soft tissue and into the bone at the anchor receiving site and passing over the locating wire an inner/outer cannula system which includes an inner cannula having a sharp distal tip, and an axial lumen therethrough sized to accommodate the positioning wire and an outer cannula having a distal end, and an axial lumen therethrough sized to accommodate the inner cannula and coaxially receiving the inner cannula, the distal end being tapered wherein to present a gradually increasing profile and wherein the distal tip of the inner cannula extends distally beyond the end of the distal end of the outer cannula. The sharp distal tip of the inner cannula passes through the soft tissue to create an opening therethrough and the tapered distal end of the outer cannula passes through the opening to expand the opening and minimize removal, cutting and disturbance of the tissue as it passes therethrough. The suture anchor passes through the outer cannula and is driven into the bone at the anchor site. | 05-05-2011 |
