SYSTEMS, DEVICES AND METHODS FOR STABILIZING BONE
First Claim
1. A stabilization device configured to self-expand from a compressed delivery configuration to an expanded deployed configuration, the stabilization device comprising:
- an elongate shaft having two or more continuous curvature of bending struts, wherein the struts extend from the shaft more in the deployed configuration than in the delivery configuration;
a proximal region having a first releasable attachment configured to attach to an inserter; and
a distal region having a second releasable attachment configured to attach to the inserter.

Abstract
Described herein are devices, systems, and methods for treating bone, particularly for restoring bone dimension in compression fractures. Self-expanding stabilization devices for repairing bone may include two or more continuous curvature of bending struts that extend from a central shaft in the deployed configuration. The stabilization device may be attached to an inserter. An inserter may be used to hold the stabilization device in a collapsed delivery configuration so that it can be inserted into bone. In use, the stabilization device may be part of a system or kit for installing the device into a bone region and allowing it to expand to correct a bone fracture.

13. A self-expanding stabilization device for stabilizing a body cavity, the device comprising:
-
an elongate shaft having a plurality of continuous curvature of bending struts extendable therefrom, the shaft adapted to be positioned within cancellous bone and having an expanded deployed profile and a collapsed delivery profile; a proximal region configured to releasably connect to a first portion of an inserter; a distal region configured to releasably connected to a second portion of an inserter; wherein the shaft is adapted to cut through cancellous bone during expansion from the collapsed delivery profile to the expanded deployed profile; and further wherein the shaft is adapted to abut a surface of cortical bone adjacent the cancellous bone without passing there through.
