  • Suture passer and method of operating same
    Patent number: 9936946
    Abstract: A suture passer includes a stylet and a cannula having an open distal end defining a cannula outer diameter. The stylet has a proximal segment configured for receipt within the cannula and including a suture retention notch, and a distal segment having an expanded outer diameter substantially matching the cannula outer diameter. The distal segment of the stylet terminates at a distal cutting edge. The suture passer includes a retracted position in which the proximal segment of the stylet is received within the cannula through the open distal end and a shoulder defining a transition between the proximal segment and the distal segment abuts the open distal end of the cannula, and an extended position in which the suture retention notch is distally disposed relative to the open distal end of the cannula.
