<p>An instrument 20 for closing trocar puncture wounds having a handle assembly 26 with a stationary portion 28 and a movable portion 30; an elongated portion 32 attached at a proximal end thereof to the stationary portion of the handle assembly; and needle deploying means 36 associated with the elongated portion. The needle deploying means includes: an actuator member 66 having a proximal end operably connected to the movable portion of the handle assembly and a distal end disposed adjacent a distal end of the elongated portion, the actuator member being slidable between a first position and a second position; and at least one needle carrier member 50, 52 mounted adjacent the distal end of the actuator member, the needle carrier being slidable relative to the actuator member upon movement thereof, between a retracted position substantially within the elongated portion and an extended position substantially without the elongated portion. The instrument of the present invention also provides a novel suture retaining feature including at least one elongated channel 108 disposed along the actuator member such that a length of suture may be received and retained within the channel and carried therein, between the elongated portion and the actuator member. <IMAGE></p> |
