IMPLANTABLE DEVICES AND METHODS FOR TREATING MICRO-ARCHITECTURE DETERIORATION OF BONE TISSUE
First Claim
1. A method for treating bone by implanting a self-expanding stabilization device, the method comprising:
- holding a self-expanding stabilization device in a collapsed delivery configuration, wherein the stabilization device comprises an elongate tubular body having a plurality of expandable struts further wherein the stabilization device is held in the collapsed configuration by a delivery device coupled to the stabilization device;
inserting the collapsed stabilization device into a bone;
allowing the stabilization device to self-expand into an expanded deployed configuration so that the struts cut through the bone as they expand;
removing the delivery device from the stabilization device; and
securing the stabilization device within the bone by applying material in and around the stabilization device.

Abstract
An expandable stabilization device is disclosed that is suitable for deployment within cancellous bone, including, for example, within a vertebral body of a spine. The device comprises: an elongate expandable shaft adapted to be positioned within a vertebral body having a first profile and a second profile; wherein the shaft is adapted to cut through cancellous bone within the vertebral body during expansion from the first profile to the second profile; and further wherein the shaft is adapted to abut a surface of cortical bone within the vertebral body without passing therethrough. The invention also includes a method for treating cancellous bone, such as cancellous bone of a vertebral body. The method comprises: delivering an expandable device within the cancellous bone of in an interior of a vertebral body; expanding the delivered device within the cancellous bone of the vertebra body; applying force from a surface of the device to an inner surface of a cancellous bone of the vertebral body sufficient to cut through the cancellous bone; and applying force from a surface of the device to an inner surface of a cortical bone of the vertebral body sufficient to support the vertebral body.

11. A method for treating bone by implanting a self-expanding stabilization device, the method comprising:
-
holding a self-expanding stabilization device in a collapsed configuration, wherein the stabilization device comprises an elongate body having a plurality of expandable struts and wherein the stabilization device is coupled to a delivery device so that a control rod passes through a central lumen of the stabilization device and couples to the stabilization device near the distal end of the stabilization device; inserting the collapsed stabilization device into a bone; allowing the plurality of struts of the self-expanding stabilization device to expand and cut through bone; and securing the expanded stabilization device within the bone by applying cement in and around the stabilization device. - View Dependent Claims (12, 13, 14, 15, 16, 17, 18, 19)

20. A method for treating bone by implanting a self-expanding stabilization device, the method comprising:
-
holding a stabilization device in delivery configuration by preventing a plurality of self-expanding struts of the stabilization device from expanding; inserting the stabilization device into a cancellous bone; allowing the struts of the stabilization device to self-expand and cut through the cancellous bone; and stabilizing the stabilization device within the bone by administering a material through the stabilization device to fill the region in and around the stabilization device.
