International Classification:

A61F 208

US Classification:

623 1314, 606 72, 606 96

Abstract:

A method and apparatus for reconstructing a ligament using a graft ligament support block which comprises a body, and a graft hole and a transverse fixation pin hole extending through the body, with both the graft hole and the fixation pin hole preferably extending substantially perpendicular to the longitudinal axis of the body. A graft ligament is looped through the graft hole, and the support block is advanced into the bone tunnel, with the two free ends of the looped graft ligament extending back out the bone tunnel. Next, a transverse tunnel is formed in the host bone, with the transverse tunnel being aligned with the fixation pin hole. Then the support block is secured in place by pinning the support block within the tunnel, i. e. , by advancing a fixation pin along the transverse tunnel in the host bone and into the fixation pin hole in the support block.

US Classification:

623 1314, 606 72, 606 96

Abstract:

Method and apparatus for reconstructing a ligament. A graft ligament support block comprises a body, a graft hole, and a transverse fixation pin hole extending through the body. An installation tool is provided for inserting the support block into a bone tunnel and forming a transverse tunnel aligned with the pin hole. In use, a graft ligament is looped through the graft hole, and the support block is mounted to the tool. The tool is used to advance the support block into the bone tunnel, with two free ends of the graft ligament extending out the bone tunnel. A transverse tunnel is formed aligned with the pin hole. The support block is secured in place by pinning the support block within the tunnel by advancing a fixation pin along the transverse tunnel and into the pin hole in the support block.

Appl. No.:

11/805223

Inventors:

Peter Marshall - Bolton MA, US
Dennis Hubbard - Lancaster MA, US

Assignee:

Scandius Biomendical, Inc. - New Haven CT

International Classification:

A61B 17/10
A61B 17/04
A61B 17/12

US Classification:

606144, 606139

Abstract:

An apparatus for suturing tissue includes first and second needles. A first structure associated with the first needle is adapted and configured to pass a leading portion of the suture from a near side of a tissue to a far side of the tissue. A second structure cooperates with the second needle to capture and secure the suture. Proximal movement of the apparatus after the suture is captured moves the suture from the far side of the tissue to the near side of the tissue.

US Classification:

606 86R, 606 88, 606144

Abstract:

A graft ligament strand tensioner is provided. The tensioner includes a body, a pair of suture rails connected to the body and a handle pivotally connected to the body. Each suture rail comprises a grooved outer channel for receiving a suture loop and a central mandrel for receiving a suture loop. The handle is pivotally connected to the body such that the handle can be pivoted relative to a longitudinal axis of the body only when the handle is under tension.

US Classification:

606144, 606139

Abstract:

An apparatus for suturing tissue includes a housing. The apparatus also includes a first needle attached to the housing and a second needle attached to the housing. A suture having a leading portion and a trailing portion is also included. A first structure is operably associated with the first needle for passing the leading portion of the suture from a near side of body tissue to a far side of the body tissue. A second structure is operably associated with the second needle for retracting the leading portion of the suture from the far side of the body tissue back to the near side of the body tissue.
