Patent number: 8398790Abstract: A femoral stem hip implant for insertion into a surgically created aperture in a femur includes a monolithic femoral stem made of shape memory material. The stem is configured to be inserted into the aperture, has a proximal portion and a longitudinal axis. The shape memory material within the proximal portion has a cross-section perpendicular to the longitudinal axis. At least a portion of the shape memory material within the proximal portion is in a compressed state by application of a plurality of compressive forces at a temperature below an austenitic finish temperature of the shape memory material so that the cross-section expands through shape memory effect via the formation of austenite in response to a temperature increase after insertion into the aperture thereby causing a locking-force to be exerted against an inner surface of the aperture, the locking force being sufficient to stabilize the implant in the aperture.Type: GrantFiled: January 17, 2012Date of Patent: March 19, 2013Assignee: MX Orthopedics, Corp.Inventor: Matthew V.

Patent number: 8137486Abstract: A method for arthroplasty includes using a self-locking prosthesis that has a member structured to transfer a load produced by the weight of a patient to a bone. An expandable bone-locking portion that is integral to the member includes a shape-memory material and expands to produce a locking force. A portion of the bone is removed to form an aperture in the bone. The bone-locking portion is inserted into the aperture, and a temperature increase causes a change from a contracted state to an expanded state resulting in expansion of the bone-locking portion so as to contact the inner surface. The expanding is sufficient to create a locking force at the junction between the inner surface and the bone-locking portion of the prosthesis and the majority of the locking force is applied at or above the metaphysis. The length/width ration of the prosthesis may be less than or equal to 5. The resulting reconstructed long-bone may have improved primary and long-term stability.Type: GrantFiled: April 21, 2011Date of Patent: March 20, 2012Assignee: MX Orthopedics, Corp.Inventor: Matthew V.

Publication number: 20110071633Abstract: Illustrative embodiments of the present invention are directed to a method for coating a shape-memory prosthesis. The method includes providing a prosthesis with an expandable portion. The expandable portion comprises a shape-memory material having a contracted phase and an expanded phase. A temperature increase past a phase transition temperature causes a change from the contracted phase to the expanded phase. The method also includes applying a coating to at least a portion of the shape-memory material using a thermal deposition application and simultaneously cooling the shape-memory material and the coating with a cryogenic vapor to prevent at least a portion of the shape-memory material from transitioning to the expanded phase.Type: ApplicationFiled: September 23, 2010Publication date: March 24, 2011Applicant: MX ORTHOPEDICS CORP.Inventor: Matthew V.
