摘要： A needle assembly for passing suture within the body includes a rigid needle having a proximal end and a pointed distal end, and an opening in the distal end extending through the needle for retaining a suture therein; a stop element positioned on the needle proximate to, and spaced from, the proximal end of the needle; a sheath having a lengthwise bore therethrough for slidably retaining the needle; and a lock member engageable with the needle stop element to prevent distal movement of the needle in the sheath bore. The needle distal end is movable to an exposed position for passing the assembly through tissue, and is movable to a shielded position within the sheath for passing the assembly safely past the tissue which is not to be penetrated. There is further contemplated a method for passing suture within the body, using the needle assembly.
