#$%^&*AU2016201289A120160317.pdf#####Abstract A method and system is provided for passing a suture anchor through a soft 5 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 10 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 15 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. 20 29/02/16,dh-18881 specidoc,21/5 18 16 22 0 22 36 12 20 24 FIG. 13 26 1 3 0 3 2 10- 28 FIG. 2 36 34 36 FIG. 3
