Abstract
Arthrodesis devices and arthrodesis procedures are disclosed herein. In an embodiment, an arthrodesis device includes a shape memory material connecting member attached to two points of fixation.
Claims20
An arthrodesis device, comprising:
- a sleeve;
- a fixation body movably received in the sleeve;
- a shape memory material connecting member connected to the fixation body,
- wherein the fixation body is a separate component from the shape memory material connecting member;
- and
- a tensioning device connected to the fixation body and configured to move the fixation body inside the sleeve when tensioned,
- wherein the tensioning device is a cable received through a non-threaded opening of the fixation body.
4 more elements
A method of performing an arthrodesis procedure, comprising:
- positioning an arthrodesis device within a joint;
- tensioning a tensioning device of the arthrodesis device,
- wherein tensioning the tensioning device stretches a shape memory material connecting member of the arthrodesis device from an unstretched condition to a stretched condition;
- and
- releasing tension on the tensioning device,
- wherein releasing the tension on the tensioning device causes the shape memory material connecting member to move back toward the unstretched condition, thereby applying a compressive load across bones of the joint,
- wherein the tensioning device is received through a non-threaded opening of a distal body that is movably received within the arthrodesis device, and the shape memory material connecting member is removably connected to a threaded opening of the distal body.
4 more elements
An arthrodesis device, comprising:
- a sleeve;
- a first body located within the sleeve;
- a second body located within the sleeve;
- a Nitinol rod removably connected to both the first body and the second body;
- and
- a tensioning cable connected to the first body or the second body,
- wherein the tensioning cable is tensionable to move the first body or the second body inside the sleeve, thereby stretching the Nitinol rod,
- wherein the Nitinol rod is a separate component from either the first body or the second body.
