    • The present invention relates in certain embodiments to systems and methods for treating bone, such as vertebral compression fractures. In one embodiment, a method includes controllably applying energy from an energy source to a bone cement volume outside of a patient's body to selectively accelerate the polymerization rate of the bone fill material volume prior to introduction of the bone fill material into a bone. The method further includes sequentially introducing a plurality of cement carrying structures with said accelerated polymerization rate bone cement volume into the bone. A system for use in said method includes at least one elongated cement-carrying structure sized to carry a bone cement volume therein and an energy source operatively coupleable to the cement- carrying structure. The energy source applies energy to the bone cement volume to selectively accelerate a polymerization rate thereof. An elongated injector is insertable into the bone and has a passageway that removably receives the elongated cement- carrying structure to allow delivery of the accelerated polymerization rate bone cement into the bone.
    • 本发明在某些实施方案中涉及用于治疗骨的系统和方法,例如椎体压缩性骨折。 在一个实施例中,一种方法包括将能量源可控地施加到患者身体外部的骨水泥体积,以在将骨填充材料引入骨骼之前选择性地加速骨填充材料体积的聚合速率。 该方法还包括将具有所述加速聚合速率骨水泥体积的多个水泥承载结构顺序地引入骨中。 用于所述方法的系统包括尺寸适于承载骨水泥体积的至少一个细长的水泥承载结构,以及可操作地连接到承载结构的能量源。 能量源将能量施加到骨水泥体积以选择性地加速其聚合速率。 细长的注射器可插入到骨中,并且具有可移除地容纳细长的水泥承载结构以允许将加速的聚合速率骨水泥输送到骨中的通道。

    • Various embodiments of the invention provide polymeric compositions including PTC composites that exhibit highly non-linear PTC effects together with extremely rapid, repeatable switching within a predetermined temperature range. In one embodiment, the polymer composite includes a polymer base material with dispersed conductive particles that have very low densities and very low thermal conductivity properties. The conductive particle component can comprise hollow glass microspheres to provide low mass and low thermal conductivity properties together with a nanoscale conductive cladding of silver or gold. The conductively clad microspheres have a core portion with a bulk density of less than about 2.0 g/cm3 and a mean thermal conductivity of less than about 5.0 W/m-oK.
    • 本发明的各种实施方案提供了包含PTC复合材料的聚合物组合物,其在预定温度范围内显示高度非线性的PTC效应以及非常快速,可重复的切换。 在一个实施方案中,聚合物复合材料包括具有分散的导电颗粒的聚合物基体材料,其具有非常低的密度和非常低的导热性能。 导电颗粒组分可以包括中空玻璃微球,以提供低质量和低导热性以及银或金的纳米级导电包层。 导电包覆的微球体具有堆积密度小于约2.0g / cm 3并且平均热导率小于约5.0W / m-oK的核心部分。
