The insertion rod is then removed from the tunnels formed in the bone and the flexible strand is held looped over the second drill point. Subsequently, a soft tissue replacement is affixed to one end of the flexible strand and pulled over up to the first drill point with the other end of the flexible strand. The first drill point is then used to pull a cross pin through the transverse tunnel to hold the looped end of the soft tissue replacement in place.Type: ApplicationFiled: February 28, 2011Publication date: June 23, 2011Applicant: Biomet Sports Medicine, LLCInventors: Troy M.

Patent number: 7963984Abstract: A novel fixation system for fixing a graft ligament in a bone tunnel. The fixation system comprises an interference screw comprising a body having a distal end and a proximal end, screw threads extending longitudinally along the body, and a transversely-extending region formed in the body for receiving a transverse pin therein, whereby to securely lock the interference screw, and hence the graft ligament, to the bone. In accordance with a further feature of the present invention, there is provided a method for attaching a graft ligament to a bone, the method comprising the steps of: (i) drilling a tunnel in the bone; (ii) positioning the graft ligament in the bone tunnel; (iii) placing an interference screw in the bone tunnel so as to force the graft ligament laterally against the opposite side of the bone tunnel; and (iv) advancing a transverse pin transversely through the bone and through the interference screw so as to securely lock the interference screw, and hence the graft ligament, to the bone.Type: GrantFiled: June 8, 2007Date of Patent: June 21, 2011Assignee: Stryker Ortho PedicsInventors: E.

Publication number: 20110137416Abstract: A system for single tunnel, double bundle anterior cruciate ligament reconstruction includes implant constructs and instruments. The implant constructs provide a combination of cortical fixation and bone tunnel aperture fixation. The implant constructs separate a graft into distinct bundles. The instruments are used to prepare shaped bone tunnels to receive the implant constructs and graft bundles. Methods for reconstructing the antero-medial and postero-lateral bundles of the anterior cruciate ligament may rely on single femoral and tibial tunnels and a single strand of graft.Type: ApplicationFiled: February 14, 2011Publication date: June 9, 2011Applicants: MEDICINELODGE, INC.

Patent number: 7955388Abstract: System, including methods, apparatus and components thereof, and kits, for connecting to bone using an anchor element configured to be anchored in bone and having a selectively bendable hinge region. In some embodiments, the system may connect the anchor element to connective tissue, a bridge member, and/or to another anchor element by bending the hinge region while the anchor element is disposed in bone, thereby connecting bone to the connective tissue or bridge member, and/or connecting bone members.Type: GrantFiled: October 30, 2007Date of Patent: June 7, 2011Assignee: Acumed LLCInventors: David G. Jensen, Steven P. Horst

Publication number: 20110118838Abstract: A placement assembly used for positioning and holding a ligament graft within a selected bone tunnel. The assembly includes a graft pulley, a surgical suture, and a graft pulley placement instrument. The graft pulley includes a pulley portion and a bone anchoring portion. The pulley portion is adapted to receive the surgical suture and for surgical suture to be drawn through it, to act as a pulley. The bone anchoring portion comprises a portion adapted to selectively fix the graft pulley within a bone tunnel. The graft instrument may be selectively attached to the graft pulley and includes a handle and elongate body, adapted to insert the graft pulley into the selected bone tunnel. Once the graft pulley is in place, the placement instrument may then be detached and withdrawn leaving the graft pulley firmly fixed within the bone tunnel and can then be used to position a ligament graft.Type: ApplicationFiled: March 31, 2010Publication date: May 19, 2011Inventors: George Delli-Santi, Alan W. Wolf

Publication number: 20110112641Abstract: A graft fixation system for fixing graft material in a bone tunnel includes an expandable fixation member having a graft receiving eyelet disposed proximate its distal end, opposed bone engaging elements disposed about its periphery, and an expansion plug receiving opening defined in its proximal end. The system also includes an expansion plug having a diameter greater than the diameter of the expansion plug receiving opening so that forcible insertion of the expansion plug into the expansion plug receiving opening causes an expansion of the expandable fixation member driving the opposed bone engaging elements apart so as to fix the bone engaging elements, as well as the graft material, in a bone tunnel.Type: ApplicationFiled: January 20, 2011Publication date: May 12, 2011Applicant: DePuy Mitek, Inc.Inventors: Daniel F.

Publication number: 20110106252Abstract: A tendon anchoring device may include an implant having a pair of spaced apart legs for straddling a tendon. A push rod removably attached to the implant may be utilized to guide and push a portion of the tendon into a pre-drilled bore in a bone. A fixation member may be slid along the push rod and threadably engage an inner surface of the pre-drilled bore to thereby anchor the tendon to the bone while a force is applied to the push rod. Once the fixation member has been installed, the push rod may be disengaged from the implant and removed from the bore. The implant may remain permanently straddled over the tendon inside of the bore.Type: ApplicationFiled: April 19, 2010Publication date: May 5, 2011Inventors: Shane Barwood, Farnaz L. Yassaee

Patent number: RE42526Abstract: A method of securing a graft in a bone tunnel, in which graft is secured within the tunnel at both the entrance and the exit ends of the tunnel to provide bicortical fixation of the graft in the bone. Interference screws or other fixation devices are used to secure the graft within the tunnel. For tibial tunnel fixation using an interference screw, the back end of the distal screw is angled so that it closely approximates the angle of the outer tibial tunnel rim. The distal screw is non-cannulated to prevent hematomas from being formed by blood flowing from the tibial tunnel into the surrounding soft tissue. The proximal screw has a restricted cannula to minimize the flow of synovial fluid entering the tibial tunnel. Advantageously, the space between the two screws fills with blood to promote faster healing and incorporation of the graft in the tibial tunnel.Type: GrantFiled: June 12, 2003Date of Patent: July 5, 2011Assignee: Arthrex, Inc.Inventors: Bernard Reiser, Reinhold Schmieding
