    • The present invention relates in certain embodiments to medical devices for treating osteoplasty procedures such as vertebral compression fractures. More particularly, embodiments of the invention relate to instruments and methods for controllably restoring vertebral body height by controlling the geometry of fill material introduced into cancellous bone. A system 100 utilizes Rf energy in combination a conductive bone fill material 120 for polymerizing the surface of the inflow plume 165 to control the geometry of the fill material 120 and the application of force caused by inflows of fill material 120. In another embodiment, the method of treating bone includes injecting a volume of fill material 120 into a bone and selectively modifying a viscosity of a selected portion of the bone fill material 120 to control the direction of flow of the fill material 120 within the bone 90. The method can also include controlling at least one flow parameter of the flow of bone fill material 120. A system 100 for treating bone using this method includes an introducer 110A, 110B for delivering fill material 120 into the bone 90 and an energy source 125A selectively coupleable to the fill material 120 to alter the viscosity of the fill material 120 as it flows out of the introducer 110A, 110B.
    • 本发明在某些实施例中涉及用于治疗诸如椎骨压缩性骨折之类的骨整形手术的医疗装置。 更具体地说,本发明的实施例涉及通过控制引入松质骨的填充材料的几何形状来可控地恢复椎体高度的器械和方法。 系统100利用Rf能量结合导电骨填充材料120来聚合流入羽流165的表面以控制填充材料120的几何形状和由填充材料120的流入引起的力的施加。在另一个实施例中, 治疗骨的方法包括将一定体积的填充材料120注入到骨中并选择性地改变骨填充材料120的选定部分的粘度以控制填充材料120在骨90内的流动方向。该方法还可以 包括控制骨填充材料120的流动的至少一个流动参数。用于使用该方法治疗骨骼的系统100包括用于将填充材料120输送到骨骼90中的导入器110A,110B以及可选择地与填充物耦合的能量源125A 材料120以在填充材料120流出导引器110A,110B时改变填充材料120的粘度。
