    • Instrumentation and method for treatment of a spinal structure, comprising an elongate member (22) including a deformable distal portion (22a) having an initial configuration for placement within the spinal structure and a deformed configuration wherein the distal portion (22a) is outwardly deformed to form a cavity (C) in the spinal structure. The elongate member (22, 122) comprises a cannula member (32) and an actuator member (30) that is removably positioned within the cannula member (32) and configured to transition the deformable distal portion (22a) from the initial configuration toward the deformed configuration. The actuator member (30) is selectively removed from the cannula member (32) to provide a passageway (60) for delivery of a material (M) into the cavity (C) formed in the spinal structure.
    • 用于治疗脊柱结构的仪器和方法,包括细长构件(22),所述细长构件(22)包括具有用于放置在所述脊柱结构内的初始构型的可变形远端部分(22a)和变形构造,其中所述远端部分(22a)向外变形 在脊柱结构中形成腔(C)。 细长构件(22,122)包括套管构件(32)和致动器构件(30),其被可移除地定位在套管构件(32)内并且构造成使可变形远侧部分(22a)从初始构型朝向 变形配置。 致动器构件(30)从套管构件(32)中选择性地移除,以提供用于将材料(M)输送到形成在脊柱结构中的空腔(C)中的通道(60)。
