Claim Text:
1. A device for repairing a tear in a portion of tissue, comprising: a proximal actuator portion; a transfer needle extending distally from the proximal actuator portion and having a distal tip for piercing tissue; a catch needle extending distally from the proximal actuator portion and having a distal tip for piercing tissue; a suture needle disposed within a lumen in said transfer needle, said suture needle being extendable from said transfer needle toward said catch needle and retractable from said catch needle toward said transfer needle, the suture needle having first and second opposed surfaces; and a window disposed on said transfer needle, through which said suture needle may be deployed, said window having two substantially parallel sides, a bearing surface which is disposed substantially perpendicularly to a path of the suture needle as the suture needle traverses into and out of said window, the bearing surface defining a distal edge of the transfer needle window, and an interference zone defining a proximal edge of the transfer needle window; wherein the first surface of the suture needle and the interference zone of the transfer needle window contact one another interferingly when the suture needle traverses into and out of said window as it is extended toward said catch needle and retracted toward said transfer needle, and the second surface of the suture needle and the bearing surface of the transfer needle window also contact one another when the suture needle traverses into said window.
