SYSTEMS AND METHODS FOR CLOSING A VESSEL WOUND

摘要

Vessel wound closure systems and method for sealing a puncture wound in a target vessel, such as those puncture wounds that occur from prior interventional procedures. A sealing member (40) is deployed intravascularly into the target vessel, and an anchor member (50) is deployed extravascularly of the target vessel. The sealing member and the anchor member are connected by a suture (60) that may be drawn to tighten the sealing member and the anchor member relative to one another in order to effect the seal of the puncture wound. After tightening, the suture is secured to maintain the sealing member and the anchor member relative to one another in order to maintain the seal. Preferably, the anchor member, the suture and the sealing member are comprised of biocompatible, bioresorbable materials that are absorbed into the body after the sealing of the puncture wound has been achieved. The sealing member, suture and the anchor member are delivered by a delivery rod (50) or other components over a guidewire (30) or through an introducer already in place from the preceding interventional procedure.
