Patent number: 6808527Abstract: An intramedullary nail has a dynamization opening that accommodates and utilizes a dynamization window insert. The dynamization window insert is press-fit into the dynamization opening. The dynamization window insert is oval shaped and includes first and second protrusions that extend from respective surfaces of the dynamization window insert. The dynamization opening is sized to receive the dynamization window insert but compress the protrusions/window insert during insertion. The dynamization opening includes channels or grooves that are sized to accommodate the protrusions and allow the protrusions/window insert to return to an uncompressed state when situated therein. The dynamization opening and window insert cooperate to allow a press fit of the window insert into the dynamization opening with an elastic snap-fit and audible sound.Type: GrantFiled: March 25, 2002Date of Patent: October 26, 2004Assignee: DePuy Orthopaedics, Inc.Inventors: Jerry L.

Patent number: 6793676Abstract: A method of reconstructing a joint having two bones separated by cartilaginous material is provided. The method comprises the steps of removing a portion of the cartilaginous material to create a defect site, positioning an anatomically shaped reconstructive structure comprising multiple layers of submucosa and having a thickness of about 1 to about 12 millimeters adjacent to the defect site, and securing the reconstructive structure to the defect site. The method can further comprise the steps of positioning a barrier layer between the bleeding bone and the reconstructive structure, securing the barrier layer to the bleeding bone, and securing the reconstructive structure to the barrier layer.Type: GrantFiled: January 23, 2001Date of Patent: September 21, 2004Assignee: DePuy Orthopaedics, Inc.Inventors: Pamela L.

Patent number: 6780188Abstract: A pin (20) is provided for securing a replacement ligament (24) inside a tunnel (10) of a receptor bone (36). A threaded section (30) of the pin (20) engages and anchors the pin (20) in the receptor bone (36). A first taper (26) opposite the threaded section (30) is configured to enter a drilled hole (14) which is transverse to the tunnel (10), capture a looped replacement ligament (24), and extend into the medial side (25) of the receptor bone (36). A second taper (28) urges the replacement ligament (24) against the wall (15) of the tunnel (10) and provides resistance when the second taper (28) contacts the medial side (25) of the bone (36), thus signaling that the pin (20) has been inserted to the proper depth. The body (21) of the pin (20) secures the looped replacement ligament (24) in the tunnel (10) and holds the replacement ligament (24) in contact with the wall (15) of the tunnel (10) to insure ingrowth.Type: GrantFiled: October 22, 2001Date of Patent: August 24, 2004Assignee: Ethicon, Inc.Inventors: Ron Clark, Jerry L.

Patent number: 5643320Abstract: A preassembled disposable driver and suture anchor are provided for threaded engagement into a bone to provide an attachment point for soft tissue. The anchor is formed to have an externally threaded body portion for engaging the bone, a distal end portion, and a proximal end portion. When the anchor is threaded into an opening in a bone, the distal end portion is adjacent a bottom of the opening and the proximal end portion is adjacent a mouth of the opening. A suture is attached to said anchor having free ends extending outwardly from the bone opening. The driver is elongated and has a distal end which engages the proximal end of the anchor and a proximal end for gripping by the surgeon. The driver also has a slot for receiving the suture which extends away from the anchor.Type: GrantFiled: March 13, 1995Date of Patent: July 1, 1997Assignee: DePuy Inc.Inventors: Jerry L. Lower, E.

Patent number: 5613971Abstract: A bone drill guide having at least a first arm slidable within a bore of the body of the drill guide and a ratchet mechanism for locking the first arm and the first bore. The ratchet mechanism includes teeth on the first arm and a pawl biased along a first axis and having a continuous engagement edge for engaging the teeth of the first arm for any angular orientation of the pawl about the first axis. The continuous engagement edge is a curve in a plane transverse to the first axis for providing a substantially renewable point contact with the teeth. The recess includes side walls tapered towards the engagement edge to allow a narrow contact at the engagement edge and re-enforce face walls to absorb the axial forces of the guide.Type: GrantFiled: August 11, 1995Date of Patent: March 25, 1997Assignee: Depuy Inc.Inventors: Jerry L.

Patent number: 5562671Abstract: A method is provided for installing a femoral bone plug in a femoral tunnel formed in a femur. The method includes the steps of inserting the femoral bone plug into the femoral tunnel, and installing a transverse pin through the femur generally perpendicular to a longitudinal axis of the femoral tunnel and intersecting the femoral tunnel. The transverse pin engages the femoral bone plug to force the femoral bone plug against a wall of the femoral tunnel to secure the femoral bone plug inside the femoral tunnel and to promote healing and bonding of the femoral bone plug to the femur.Type: GrantFiled: September 26, 1994Date of Patent: October 8, 1996Assignee: DePuy Inc.Inventors: E.

Patent number: 5354300Abstract: A drill guide is provided for aligning and installing a transverse pin through a tunnel formed by a tunnel drill in a bone to secure a ligament replacement to the bone. The drill guide includes an arm member and a drill guide sleeve coupled to the arm member. The drill guide sleeve is formed to include a central bore for guiding a drill to form a transverse guide hole in the bone to guide insertion of the transverse pin into the bone. The central bore of the drill guide sleeve has an axis which is aligned to intersect the tunnel. The arm member of the drill guide is coupled to the tunnel drill while the tunnel drill is still in the bone to align the arm member and drill guide sleeve at a desired anatomical location using the tunnel drill in the bone as a reference.Type: GrantFiled: January 15, 1993Date of Patent: October 11, 1994Assignee: Depuy Inc.Inventors: E.
