International Classification:

A61B 1732

US Classification:

606170, 606180

Abstract:

An atherectomy burr has an operating diameter that is larger than the diameter of a catheter in which the burr is routed. The burr may include a polymeric balloon that is coated with an abrasive and that expands when the burr is rotated. Alternatively, the burr may include a polymeric tube that is coated with an abrasive and secured to the proximal end of the burr. When the burr is rotated, the polymeric tube expands by centrifugal force. Alternatively, the burr may comprise a metallic strip wound over a mandrel. When the strip is tightly coiled to the mandrel, its outer diameter decreases. The outer diameter of the burr increases as the metallic strip expands. In addition, the burr can be formed as a wire spring wound over a drive tube. The distal end of the spring is coupled to a nose cone that can move within a distal lumen in the drive tube. The maximum expansion of the burr is controlled by the distance that the nose cone can be retracted into the lumen.

US Classification:

419 28, 419 36, 419 37

Abstract:

A method for manufacturing complex shape memory alloy materials is described. The method comprises generating a particulate form of a shape memory alloy, combining the particulate with a binder, molding, heating (which may include the steps of debinding and sintering), and thermo-mechanical processing. The method allows for the formation of complex shape memory alloy materials that exhibit the desirable properties of shape memory alloys, namely shape memory and superelasticity.

International Classification:

A61C 17/02

US Classification:

433 89

Abstract:

The guidance assembly is used for precise cleaning of interproximal spaces of teeth. The guidance assembly includes a base portion () for contacting the surfaces of teeth and gum region, adjacent the interproximal space, the base portion being approximately 12 mm in diameter to provide stable contact with the teeth and gum region. The guidance assembly also includes a tip portion () which extends forward of the base portion and includes an opening () through which the droplet spray is directed coincident with the plane of the interproximal space.

International Classification:

A61B 1700

US Classification:

606 88

Abstract:

A system and method for positioning a tool relative to a patient's bone to facilitate the performance of a surgical bone alteration task. The system comprises a bone immobilization device for supporting the bone in a fixed position with respect to a reference structure, and a robot that includes a base fixed in position with respect to the reference structure. The bone imobilization device includes two semicircular frame pieces having a plurality of radial apertures through which bone gripping components adjustably extend in order to contact the bone. The bone gripping components include a shaft with a point inserted through a shaft bore of a serrated bone contact element. A support attaches to the frame to adjustably secure and position the frame relative to the reference structure.

Abstract:

A system and method for positioning a tool relative to a patient's bone to facilitate the performance of a surgical bone alteration task. The system comprises a bone immobilization device for supporting the bone in a fixed position with respect to a reference structure, and a robot that includes a base fixed in position with respect to the reference structure. The robot also includes a mounting member, and a manipulator connected between the base and the mounting member and permitting relative movement therebetween. The tool to be positioned by the system is mounted to the mounting member. The mounting member is caused to move relative to the reference structure in response to movement commands, so that the tool can be moved to a desired task position to facilitate performance of the task. The system preferably also includes a template attachable to the mounting member, a feature of the template representing a portion of a task. Preferably, the template is secured to the mounting member, and the template is then manually manipulated such that the template feature is properly oriented with respect to the patient's bone.

International Classification:

A61B 1756

US Classification:

606 88

Abstract:

A prosthesis template for aiding in the determination of a desired position of a prosthesis relative to a bone, the prosthesis having an exterior surface that simulates the exterior surface of the bone and an interior surface comprised of one or more contact surfaces to which the prepared bone must conform to provide an adequate fit of the prosthesis. The template comprises a template member having an interior surface which corresponds to an exterior surface of the prosthesis, whereby the template can be positioned adjacent to the bone and thereby provide means for evaluating a desired position of the prosthesis exterior surface.
