Abstract
A system for piercing through biological tissue and providing access to internal structures; particularly, intra-abdominal structures, and closing an opening in the tissue. The system includes a suture guide sub-system having a tissue positioning sub-system for engaging segments of tissue disposed proximate the tissue opening and a suture passer sub-system that slideably engages the suture guide sub-system. The suture passer sub-system includes suture deployment and capture means that is configured to removably secure a suture thereto and deliver the suture to the segments of tissue disposed proximate the tissue opening.
