Abstract:
1. A tissue closure device for delivery into an opening in a blood vessel wall using a plunger and a medical device, the tissue closure device consisting of: a proximal end configured to coupled with a distal end of the plunger during advancement of the tissue closure device; a distal end; an elongate non-tapered surface with a solid core between the proximal end and the distal end; a first radially extending element extending radially outward from the surface positioned at the distal end of the tissue closure device, the first radially extending element comprising a proximal surface; and a second radially extending element extending radially outward from the surface positioned between the distal end and the proximal end of the tissue closure device, the second radially extending element comprising a distal surface; wherein the first and second radially extending elements are at least partially compressible, deformable or deflectable to have a first configuration when positioned within the medical device and a second configuration when advanced beyond a distal end of the medical device, wherein the proximal surface of the first radially extending element is adapted to contact and conform to an inner surface of the blood vessel wall near the blood vessel wall opening when the radially extending element is in the second configuration, and wherein the distal surface of the second radially extending element is adapted to contact and conform to an outer surface of the blood vessel wall near the blood vessel wall opening when the radially extending element is in the second configuration, wherein the tissue closure device is formed from a single piece.
