BONE TREATMENT SYSTEMS AND METHODS
First Claim
1. A bone treatment system comprising:
- a bone fill material injector configured to be at least partially introduced into a bone;
a handle comprising a thermal energy emitter operatively coupled to the injector, the thermal energy emitter configured for delivering energy to a flow of bone fill material through the handle;
an electronic controller configured to modulate the delivery of energy from the thermal energy emitter to the flow of bone fill material based at least in part on a sensed parameter to achieve a desired bone fill material viscosity.

Abstract
Systems and methods for treating vertebral compression fractures are discussed. In an embodiment, a method includes mixing bone cement precursors thereby causing a first chemical curing reaction characterized by a first time-viscosity profile, controllably applying energy to the bone cement from an external source to modify the first time-viscosity profile to a second time-viscosity profile, and injecting the cement into bone at a substantially constant viscosity greater than about 1000 Pa·s to greater than about 5000 Pa·s over an extended working time. In another embodiment, a bone cement injector system is provided that includes a first handle component that is detachably coupled to a second sleeve component having a distal end for positioning in bone and a flow channel extending through the first and second components. The system includes first and second thermal energy emitters for delivering energy to bone cement flows in a flow channel portion in the first and second components, respectively.
