ABSTRACT:
A suturing device (20) having a leading member (22) and a trailing member (24) for forming a double knot. The leading member (22) functions to slide a first knot (26) that is formed in the sutures (30, 32) against the surface (34) of tissue (40). A finger (60) is formed in the leading member (24) to hold the first knot (26) against the tissue surface (34) as a second knot (28) is moved by the trailing member (24) against the first knot (26). The leading member (22) is configured to part as the trailing member (24) moves the second knot (28) against the first knot (26).
