APPARATUS AND METHOD FOR SEQUENTIALLY ANCHORING MULTIPLE GRAFT LIGAMENTS IN A BONE TUNNEL

摘要

An apparatus (100) for anchoring at least two graft ligaments (102,104) within a longitudinal bone tunnel includes a longitudinal sleeve (108). The sleeve is configured for at least partial insertion into the bone tunnel (106). The graft ligaments are at least partially located between the bone tunnel and the sleeve. An actuating member (128) has longitudinally separated proximal and distal actuating member ends. An asymmetrically offset profile is defined by at least one of the sleeve and the actuating member. The actuating member is inserted longitudinally into the sleeve to cause frictional engagement of each graft ligament with both the bone tunnel and at least one ligament -contacting surface. The frictional engagement of each graft ligament is temporally spaced apart from the frictional engagement of at least one other graft ligament.
