    • 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. An exemplary system utilizes Rf energy in combination a conductive bone fill material for polymerizing the surface of the inflow plume to control the geometry of the fill material and the application of force caused by inflows of fill material. In another embodiment, method of treating bone includes injecting a volume of fill material into a bone and selectively modifying a viscosity of a selected portion of the bone filler to control the direction of flow of the fill material within the bone. A system for treating bone using this method includes an introducer for delivering fill material into the bone and an energy source selectively coupleable to the fill material to alter the viscosity of the fill material as it flows out of the introducer.
    • 本发明在某些实施例中涉及用于治疗诸如椎体压缩性骨折的骨整形术程序的医疗装置。 更具体地,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仪器和方法。 示例性系统利用Rf能量组合导电骨填充材料,用于聚合流入羽流的表面以控制填充材料的几何形状以及由填充材料的流入引起的力的施加。 在另一个实施方案中,治疗骨的方法包括将一定体积的填充材料注入骨中,并选择性地改变骨填充物的选定部分的粘度以控制填充材料在骨内的流动方向。 使用这种方法治疗骨骼的系统包括用于将填充材料输送到骨骼中的导引器,以及选择性地与填充材料耦合的能量源,以改变填充材料流出导引器时的粘度。
