Systems and methods for treating fractured or diseased bone using expandable bodies
First Claim
1. A system for treating a vertebral body having an interior voume occupied, at least in part, by cancellous bone comprising a first access tool sized and configured to establish a first percutaneous access path into the interior volume of the vertebral body, a second access tool sized and configured to establish a second percutaneous access path to the interior volume of the same vertebral body, the second access path being different than the first access path, a void forming tool sized and configured to be introduced through a selected one or more of the first and second first access tools into the interior volume to form a void in the cancellous bone.

Abstract
Systems and methods treat fractured or diseased bone by deploying more than a single therapeutic tool into the bone. In one arrangement, the systems and methods deploy an expandable body in association with a bone cement nozzle into the bone, such that both occupy the bone interior at the same time. In another arrangement, the systems and methods deploy multiple expandable bodies, which occupy the bone interior volume simultaneously. Expansion of the bodies form cavity or cavities in cancellous bone in the interior bone volume.
