摘要： An piercing member is axially fixed to and positioned within a cutter, both of which are components of a stand-alone tool for creating an opening in the wall of a tubular tissue structure. The stand-alone tool includes an impulse source connected to the piercing member and to the cutter. An actuator is operationally connected to the impulse source, where the actuator causes the impulse source to release energy to and provide an impulse to the piercing member and the cutter. The tool may be configured to make multiple openings in the tissue of the same patient. Where the tool is configured to make multiple openings in the tissue of the same patient, the tool allows the piercing member and cutter to be moved back to an initial pre-deployment position after each use

摘要翻译： 刺穿构件轴向地固定到切割器内并定位在切割器内，两者都是用于在管状组织结构的壁中形成开口的独立工具的部件。 独立工具包括连接到穿孔构件和切割器的脉冲源。 致动器可操作地连接到脉冲源，其中致动器使得脉冲源释放能量并向冲击构件和切割器提供冲击。 该工具可以被配置为在同一患者的组织中形成多个开口。 在工具被配置为在同一患者的组织中形成多个开口的情况下，该工具允许穿刺构件和切割器在每次使用之后移回到初始预部署位置
