Abstract
One embodiment is directed to a system for closing a wound created across a portion of a tissue structure, comprising a suture member having proximal and distal ends; an anchor member coupled to the distal end of the suture member; a tension retainer assembly releasably coupleable to the suture member; and a suture buttress movably intercoupled to the suture member between the anchor member and the tension retainer and configured to minimize direct sliding contact between the suture member and the tissue structure portion around the location of the suture buttress.
Claims23
A system for closing a wound created across a portion of a tissue structure, comprising:
- a suture member having proximal and distal ends;
- an anchor member coupled to the distal end of the suture member;
- a tension retainer assembly releasably coupleable to the suture member;
- and
- a suture buttress movably intercoupled to the suture member between the anchor member and the tension retainer and configured to minimize direct sliding contact between the suture member and the tissue structure portion around the location of the suture buttress,
- wherein the suture buttress is configured to be formed into a helical shape,
- wherein the helical shape has an outer helical diameter of about 21 mm with a helical pitch of about 3.5 mm,
- wherein the suture buttress is configured to be formed into between about 1 and about 2 full helical turns, and
- wherein the suture buttress is configured such that tensioning the suture member causes the helical shaped suture buttress to reduce in helical diameter, closing the wound across the tissue structure.
