Claim:
1. A method of closing or occluding a vessel, including the steps of: fitting into the vessel a vascular closure device by means of a delivery assembly, which closure device includes: a frame of tubular form and comprising a plurality of frame elements, the frame having an open lumen formed therethrough such that the vascular closure device can be carried on an introducer assembly, the vascular closure device not incorporating a plug member disposed therein, the frame being radially contractible to a small radius configuration and radially expandable; a plurality of tissue grasping elements coupled to and extending radially outwardly from at least some of the frame elements; a radial contraction mechanism, integral with the frame; the closure device being of a type detachable from the introducer assembly; the closure device being implantable in a patient; radially expanding the closure device in the vessel such that the tissue grasping elements embed into the vessel wall; allowing for radial contraction of the frame with the tissue grasping elements extending radially outward from the frame, thereby to close the vessel wall; and detaching the vascular closure device from the delivery assembly, thereby to leave the vascular closure device in the vessel in the small radius configuration, thereby to occlude the vessel.
