Abstract
A vascular closure device includes a frame to which there is fitted a plurality of anchor elements, spaced radially around the frame. The closure device includes a radial compression feature, which may be a memorized shape of the frame or non-sprung condition of the frame, having a small radius. The closure device is deployed in a vessel such that the anchor elements are embedded into the vessel wall. The radial compression feature causes the frame to compress radially, as a result of which the anchor elements will pull the vessel wall inwardly, thereby closing the vessel.
