Abstract
Among other things, embodiments of a retaining mechanism for holding a portion of the suture of a suture anchor are disclosed. When a suture anchor is inserted into a patient, the portion of the suture extending from the body is held in tension by a two-piece snap-fit mechanism. One piece has a base with an extending shaft portion and a bulbous head, and a lumen runs through the shaft. The second piece has a hole or space for snapping the second piece onto the first piece. The extending portion of the suture runs through the lumen in the first piece and can be wrapped around the shaft. Snapping the second piece onto the first contains the suture and prevents loss of tension in it.
