Filed:

Appl. No.:

10/682836

International Classification:

A61F002/40

US Classification:

623 1912

Abstract:

A dual-radius glenoid component of a shoulder joint prosthesis for use in total shoulder arthroplasty has two radii of curvature. At substantially the center of the articulating surface a first non-conforming radius of curvature is provided, while a second conforming radius of curvature, smaller than that of the first radius of curvature and more closely conforming to the curvature of the humeral component, is disposed about the periphery of the articulating surface. The central non-conforming radius of curvature provides reduced constraint of the humeral component. In contrast, the conforming peripheral radius of curvature provides maximum constraint of the humeral component. When the humeral component is substantially centered on the articulating surface reduced constraint is placed on the prosthesis and less load is transferred to the bone-implant interface. As the humeral component translates towards the periphery, constraint on the prosthesis increases to prevent dislocation.

International Classification:

US Classification:

623 2029

Abstract:

A prosthesis for repairing a knee is made with an insert sandwiched between a femoral component and a tibial tray. The parts are shaped so that both the femoral component and the tibial tray will slidingly interface with the insert during motion of the knee. At regions where the femoral component interfaces with the insert during extension and during an initial range of flexion of the knee, the femoral component's radius of curvature (R) for flexion rotation is larger than its radius of curvature (R) for varus/valgus rotation. In a preferred embodiment, the surface of the tibial tray is convex and spherically curved, and the insert is free to move in both the posterior-anterior direction and the medial-lateral direction with respect to the tibial tray.

Russell Warren - Greenwich CT

International Classification:

A01F 504

US Classification:

606 73

Abstract:

A novel surgical fastener is disclosed for attaching soft tissues (e. g. ligaments, tendons and the like) to bone and bone-like structures. The surgical fastener comprises a shank and an enlarged head disposed on one end of the shank. A central bore passes completely through the fastener along its longitudinal axis, and a plurality of diametrically projecting ribs are disposed along the length of the shank. The foregoing fastener is used to attach soft tissues (e. g. ligaments, tendons and the like) to bone and bone-like structures in the following manner.

Abstract:

A novel surgical fastener is disclosed for attaching soft tissues (e. g. ligaments, tendons and the like) to bone and bone-like structures. The surgical fastener comprises a shank and an enlarged head disposed on one end of the shank. A central bore passes completely through the fastener along its longitudinal axis, and a plurality of diametrically projecting ribs are disposed along the length of the shank. The foregoing fastener is used to attach soft tissues (e. g. ligaments, tendons and the like) to bone and bone-like structures in the following manner. First, the soft tissue is placed against the bone and then a thin guide wire is passed through the soft tissue and into the bone. A cannulated drill is then loaded coaxially onto the guide wire and is moved down the guide wire and worked on the guide wire so as to form a hole through the soft tissue and into the bone. Next, the cannulated drill is withdrawn from the guide wire and the aforementioned surgical fastener is loaded coaxially onto the guide wire.

International Classification:

A61B 5/055
A61B 5/00
G01R 33/54

Abstract:

A system that includes: a force sensor assembly adapted to monitor a load as applied on a subject’s knee joint when the force sensor assembly remains in direct contact with the subject’s lower extremity and the load is monitored from inside a main magnet of an MRI scanner; a mobile unit comprising tracks configured to adjust a position of the force sensor assembly; a stationary base on which the mobile unit and the force sensor assembly are located, the mobile unit translatable solely axially on the stationary base; and a processor coupled to the force sensor assembly and programmed to read information encoding the load being monitored by the force sensor assembly, wherein an MRI scan of the knee j oint is initiated only when a predetermined load has been applied to the subject’s knee joint for a pre-determined period of time.

Abstract:

A method for intraoperatively measuring joint contact mechanics of a patient's joint is provided. The method includes inserting a sensor between first and second bones of a joint. Then a predetermined force is applied to one of the first and second bones. Afterwards, contact mechanics such as, contact stresses, contact areas and/or forces are measured between the first and second bones in response to the applied predetermined force.
