International Classification:

A61B 17/80

US Classification:

606291, 606280

Abstract:

A bone fixation system includes a plate and a set of fixation locking screws. The plate defines a set of locking screw holes each having an internal thread. Each respective locking screw has a head with an external structure that is adapted to self-tap into the internal thread of a given locking screw hole to secure the respective first-type fixation locking screw at an surgeon-directed angle relative to the plate. This angle is defined during forcible insertion and rotation of the respective locking screw into the given screw hole. The system may also include unidirectional locking screws. In a preferred embodiment the plate and first-type of screw are made of different metals, with the plate made of titanium alloy and the screw made of cobalt chrome alloy.

US Classification:

81471, 606104, 81436

Abstract:

A torque-limiting fastener driver for driving a bone fastener into bone includes a handle supporting a driver shaft. The driver shaft includes limited components which are designed to provide feedback to a user regarding the applied torsional force. In addition, the driver shaft is designed to controllably fail before any potential uncontrolled failure of the distal driving tip. This prevents application of too much torque and controlled design of the shape and size of the failed components.

International Classification:

A61B 17/88

US Classification:

606101, 606 86 B

Abstract:

Plate shaping tools may be attached to a plate having pre-assembled guides while the plate is located on the bone to effect alteration of the plate shape in an effective and precise manner. The tools are designed such that a drill and K-wires can be inserted through the guides while the tools are coupled to the guides.

International Classification:

A61F 2/06

US Classification:

623 113

Abstract:

The present invention is directed to a prosthesis and method for treating, repairing, and/or replacing an abdominal aortic aneurysm. The prosthesis includes a coiled stent comprised of shape memory material having first and second anchoring zones and an intermediate zone. The prosthesis also includes graft material engaging at least a portion of the stent. During delivery of the prosthesis, the stent is in a substantially straight longitudinal configuration, and after delivery of the prosthesis the stent is returned to a coiled configuration. The diameter of the prosthesis may be adjusted by controlling the degree to which the stent is coiled.
