Abstract
A system is configured to create or enlarge a cavity in a tissue body and generally includes a cannula, a friction reduction covering, and a cavity creation member. The cavity creation member includes an end portion that is configured to transition between a first shape and a second shape that is different from the first shape. In operation, retracting the friction reduction covering relative to end portion causes the end portion to change shape from the first shape to the second shape such that the cavity creation member is configured to create or enlarge a cavity in the tissue body as the second end portion exits the friction reduction member.
Claims17
A method of creating or enlarging a cavity in a vertebral body, the method comprising steps of:
- inserting a friction reduction covering and a cavity creation member toward the vertebral body, wherein the friction reduction covering defines a covering opening and the cavity creation member includes an end portion substantially disposed in the covering opening;
- moving the cavity creation member relative to the friction reduction covering such that the end portion becomes increasingly displaced from the friction reduction covering;
- and
- during the moving step, transitioning the end portion from a first shape to a second shape that is different from the first shape.
