Abstract
Arthroplasty implant systems and procedures are disclosed herein. In an embodiment, an arthroplasty implant of an arthroplasty system includes a shape memory material connecting member attached to two points of fixation of the arthroplasty implant.
Claims19
An implant system, comprising:
- a sleeve extending along a longitudinal axis between a proximal portion and a distal portion;
- a proximal slider housed inside the proximal portion of the sleeve;
- a distal slider housed inside the distal portion of the sleeve;
- a Nitinol rod connected to both the proximal slider and the distal slider;
- a first opening located within the proximal portion of the sleeve;
- a first screw received through the first opening and the proximal slider;
- a second opening located within the distal portion of the sleeve;
- a second screw received through the second opening and the distal slider;
- at least one of the first opening and the second opening is an elongated slot;
- and
- a set screw removably inserted into either the proximal slider or the distal slider,
- wherein the set screw is removable from the proximal slider or the distal slider to allow the Nitinol rod to superelastically shorten.

An implant system, comprising:
- an elongated sleeve that extends along a longitudinal axis between a proximal portion and a distal portion;
- a proximal interlocking fixation body located at least partially inside the proximal portion;
- a distal interlocking fixation body located at least partially inside the distal portion;
- a shape memory material connecting member attached to the proximal interlocking fixation body and the distal interlocking fixation body;
- and
- a holding device removably connected to either the proximal interlocking fixation body or the distal interlocking fixation body.
3 more elements
A method of performing a surgery, comprising:
- inserting an implant system within a bone,
- wherein the implant system includes a shape memory material connecting member that is pre-stretched from an unstretched position to a stretched position prior to inserting the implant system;
- inserting a first fixation device through a first opening of the implant system;
- inserting a second fixation device through a second opening of the implant system;
- and
- removing a holding device from the implant system,
- wherein removing the holding device superelastically shortens the shape memory material connecting member from the stretched position toward the unstretched position.
