Abstract
Abstract A trocar wound closure device includes an elongated body having a distal end for insertion through a trocar puncture wound, a proximal end, and a first and second retractable needle holders disposed at the distal end of the body. The needle holders are movable between a retracted position and an extended position. An actuator disposed at the proximal end of the body moves the needle holders from the retracted position to the extended position, so that the needle holders can be retracted to allow the device to be inserted through a trocar wound preferably through a cannula inserted into the wound, and extended to position the needles adjacent the wound, to allow the wound to be sutured.
