Abstract
A novel surgical instrument for applying sutures through body tissue including an elongated body having a proximal end portion and a distal end portion, at least one needle carrier member operatively mounted in the distal end portion and movable between at least a retracted position and a deployed position, a needle releasably retained in the at least one needle carrier member, a predetermined length of suture material having one end affixed to the needle, and a suture material tensioning member disposed within the elongated body for maintaining the suture material in tension during movement of the at least one needle carrier member from the retracted position to the deployed position the suture material. The instrument may also include a retaining mechanism adapted to retain the at least one needle carrier in the partially deployed position, and a needle skewing mechanism operatively associated with an actuator member to change the alignment thereof relative to the retaining member. A deployment indicator may be provided to indicate to an operator of the instrument When the at least one needle carrier member is in the second position.
