Abstract
A suture punch system that is capable of directly passing braided suture through tissue in a simple, one-step process. The system includes three principle components: a malleable needle capable of delivering the suture to the tissue, a handheld instrument for grasping tissue and controlling needle placement, and a force-supplying mechanism to supply the force required for needle placement. Needle deformation begins at the tip of the instrument, which beneficially includes a curved segment. As the distal tip of the needle pierces the tissue, it continues its radial path through the tissue. When the proximal end of the needle exits from the instrument, the needle may be radial in shape and traverses an essentially radial path through the tissue. Once the needle has passed entirely through the tissue, it may be retrieved using the jaws of the punch or another instrument.
