Abstract:
1. A device for closing an aperture in a wall of a blood vessel, the device comprising: a body; at least one suture element held within the body; and at least one suture capture rod within the body, the suture capture rod being operatively associated with the suture element and arranged to pass the suture element through the vessel wall such that opposed portions of the suture element extend from the vessel wall; wherein a distal tip of the body is configured to dilate the aperture in the wall of the vessel, and wherein the distal tip has an outer surface that tapers at an angle of 3 to 7 degrees relative to a longitudinal midline of a distal portion of the device, and wherein the distal tip has a length of about 1 to 3 cm, wherein a distal-most end of the distal tip has an equivalent stiffness and smoothness to polyethylene material; a pre-mounted sheath positioned over the body, the sheath configured to move from a proximal position to a distal position along the body, the pre-mounted sheath including an occlusion element, wherein the occlusion element comprises at least one of an inflatable balloon, an inflatable cuff, a conical or other circumferential element which flares outwardly to engage an interior wall of the vessel to block flow therepast, a membrane-covered braid, and a slotted tube that radially enlarges when axially compressed.
