<p>A tension sustaining fixture, a medical system, and related methods for the suturing tissue and the tying of sutures to close a perforation made during an intracorporeal procedure are presented. A tension sustaining fixture generally comprises an elongated tube or sheath; a main body having a first passageway, the main body capable of being coupled to the elongated sheath; a side retaining sleeve coupled to the main body and whose internal surface defines a second passageway intersecting with the first passageway; a closure mechanism engaging the side retaining sleeve; the closure mechanism further defining the second passageway and sized to slidably receive at least one suture; and at least one suture having a proximal and distal end; with at least one end of a suture extending from the first passageway through the second passageway. The closure mechanism being operable between a locked configuration and an unlocked configuration; the locked configuration fixing a suture to maintain the tension applied to the suture.</p> |
