    • A spacer formed of an intermetallic compound, such as nitinol. The spacer includes two segments shaped in opposing arches. The unique properties of the intermetallic compound enable the material to be deformed into a planar, insertable shape when the material is cooled below a transition temperature and returns to the undeformed shape when the material returns to an ambient, operational temperature. An expansion mechanism assembly can engage with the spacer to apply an expansion force. The expansion force extends the spacer longitudinally drawing the spacer into the planar configuration. The expansion mechanism assembly can be used to guide the spacer into the desired position within the patient. The spacer control mechanism assembly is subsequently removed, relieving the expansion force. The spacer returns to the natural undeformed shape as it returns to body temperature. Retention features can be integrated in the spacer to aid in retaining the spacer in location.
    • 由金属间化合物如镍钛诺形成的间隔物。 间隔件包括形成相对拱形的两个段。 当材料冷却到转变温度以下时,金属间化合物的独特性能使材料变形成平面可插入的形状,并且当材料回到环境温度时,返回到未变形的形状。 膨胀机构组件可以与间隔件接合以施加膨胀力。 膨胀力将间隔件纵向拉伸成平面构型。 膨胀机构组件可以用于将间隔件引导到患者体内的期望位置。 随后移除间隔件控制机构组件,减轻膨胀力。 当返回到体温时,垫片返回到自然未变形的形状。 保持特征可以集成在间隔件中以帮助将间隔件保持在位置。

    • The instant invention describes a surgical tool for providing cavitations, or void spots, within the interior of body regions. The surgical tool is constructed and arranged to penetrate almost all interior body regions in which formation of a cavity or void space is necessary for diagnostic or treatment purposes. The surgical tool comprises an insertable member receiving structure sized and shaped to receive one or more insertable devices. The interior lumen of the insertable member receiving structure allows the insertable device to slide and/or rotate relative to the insertable member receiving structure and vice versa. At least one insertable member is a cavity forming device which has a plurality of cavity forming members constructed and arranged with spring-like characteristics for traversing between a cavity forming position and a non-cavity forming position. Upon traversal back to the cavity forming position, the displacement members retain their cavity forming structural configurations.
    • 本发明描述了用于在身体区域内部提供空穴或空穴的手术工具。 外科手术工具被构造和布置成穿透几乎所有内部​​身体区域,在这些区域中形成腔或空隙空间是诊断或治疗目的所必需的。 外科手术工具包括可插入构件接收结构,其尺寸和形状适于接收一个或多个可插入装置。 可插入构件接收结构的内腔允许可插入装置相对于可插入构件接收结构滑动和/或旋转,反之亦然。 至少一个可插入构件是空腔形成装置,其具有多个空腔形成构件,其构造和布置有弹簧状特征,用于在空腔形成位置和非空腔形成位置之间穿过。 在穿过空腔形成位置时,位移构件保持其空腔形成结构构造。
