Abstract
Various embodiments of a device are shown and disclosed for closing a vascular access puncture site following percutaneous diagnostic or therapeutic interventional procedures. The vascular closure device includes an improved plug that is configured to be positioned adjacent to the hole in the vasculature. The plug may be shaped to prevent the plug from moving away from the hole in the blood vessel due to pulsatile pressure from the blood. In one embodiment, the plug may include a plurality of projections that extend outward from the plug and contact surrounding tissue in the tissue puncture tract to prevent the plug from moving away from the hole in the blood vessel.
