Methods and devices for treating fractured and/or diseased bone using an expandable stent structure that remains within the bone
First Claim
1. A system comprising a first tool sized and configured to establish an access path through soft tissue to bone having an interior volume occupied, at least in part, by cancellous bone, an expandable stent structure sized and configured for expansion in cancellous bone, and a second tool sized and configured for passage through the access path to introduce into the cancellous bone the expandable stent structure, which remains within the cancellous bone upon removal of the second tool.

Abstract
A percutaneous path is created into a bone having an interior volume occupied, at least in part, by a cancellous bone, e.g., a vertebral body. An expandable stent structure is introduced into the cancellous bone by deployment of a tool through the percutaneous path into the cancellous bone. The expandable stent structure is expanded and the tool withdrawn, leaving the expandable stent structure expanded inside the cancellous bone. Expansion of the expandable stent structure within cancellous bone can, e.g., compact cancellous bone, and/or create a cavity in cancellous bone, and/or move fractured cortical bone.
