Abstract

Systems are provided for delivering a suture to close a surgical opening. An elongated deployment member may have at its distal end a retracted counterforce member. The counterforce member may be inserted into the surgical opening and deployed to resist being withdrawn from the opening. A compression member may be slid down the elongated member to compress the tissue to be sutured against the counterforce member. Suture passers loaded with suture ends may be passed through needle tubes within the elongated member to emerge from the elongated member and pierce the tissue to be sutured, then deposit the suture ends with a suture catcher. The suture passers may be withdrawn, leaving the suture ends. The suture catcher may be retracted, retaining the suture ends and the device—elongated member, retracted suture catcher, and retained suture end—may be withdrawn from the surgical opening. The suture may then be completed.
