6440164, Aug 27, 2002

Filed:

Oct 21, 1999

Appl. No.:

09/425142

Inventors:

Kristian DiMatteo - Watertown MA
Peter Marshall - Newburyport MA

Assignee:

Scimed Life Systems, Inc. - Natick MA

International Classification:

A61F 206

US Classification:

623 124, 623 218

Abstract:

A prosthetic valve for implantation within a fluid conducting lumen within a body includes an elongate generally cylindrical radially collapsible valve body scaffold defining a fluid passageway therethrough for retentive positioning within the lumen. A radially collapsible leaf valve member is supported by the scaffold includes a number of valve leafs deflectable between a closed position restricting fluid flow through the passageway and an open position permitting fluid flow through the passageway. The leaf valve member includes an interior leaf valve frame defining a valve leaf aperture which is sealed by a fluid impermeable non-thrombogenic lining to prevent fluid flow therethrough.

Assignee:

Scandius BioMedical, Inc. - Littleton MA

International Classification:

A61B 1756

US Classification:

606 75, 606219

Abstract:

An encapsulation device for repair of articular cartilage defects includes a body for disposition adjacent a bone in an area of the cartilage defect, and elongated leg structure extending from the body and for disposition in the bone in the area of the cartilage defect. The leg structure is provided with a length which is a plurality of magnitudes greater than a thickness of the body, and is of a generally conical configuration.

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.
