Claim:
1. A method of closing an opening in a body tissue, the method comprising: elastically deforming an elastically deformable closure clip into a first closure clip position; positioning the elastically deformed closure clip adjacent to the opening in the body tissue such that a plurality of spikes extending from an annular portion of the elastically deformed closure clip are insertable into the tissue at a location outward from a central axis of the opening, the annular portion including a plurality of upper members and a plurality of lower members, the plurality of upper members and the plurality of lower members being curved and concentric about a longitudinal axis extending through the plurality of upper members and the plurality of lower members, each upper member being separated from two adjacently positioned lower members by a pair of legs, the plurality of spikes extending from the plurality of lower members and including at least a pair of oppositely disposed spikes that are elastically separated from one another in the first closure clip position; inserting the plurality of spikes into the tissue at a location outward from the central axis with the opening; and positioning the elastically deformed closure clip, with the annular portion, in a second closure clip position such that the plurality of spikes extending from the annular portion are elastically pulled inward toward the central axis of the opening so as to pull the tissue between the opening and each of the spikes together causing the oppositely disposed spikes to cross over one another in the second closure clip position and close the opening.
