    Abstract: Embodiments described herein address the need for improved catheter devices for delivery, repositioning and/or percutaneous retrieval of the percutaneously implanted heart valves. One embodiment employs a plurality of spring-loaded arms releasably engaged with a stent frame for controlling expansion for valve deployment. Another embodiment employs a plurality of filaments passing through a distal end of a pusher sleeve and apertures in a self-expandable stent frame to control its state of deployment. With additional features, lateral positioning of the stent frame may also be controlled. Yet another embodiment includes plurality of outwardly biased arms held to complimentary stent frame features by overlying sheath segments. Still another embodiment integrates a visualization system in the subject delivery system. Variations on hardware and methods associated with the use of these embodiments are contemplated in addition to those shown and described.

    Abstract translation: 本文描述的实施例解决了对用于经皮植入的心脏瓣膜的输送,重新定位和/或经皮取出的改进的导管装置的需要。 一个实施例采用可释放地与支架框架接合的多个弹簧加载臂,用于控制阀部署的膨胀。 另一个实施例采用多个细丝穿过推进套筒的远端和自扩张支架框架中的孔,以控制其展开状态。 通过附加特征,还可以控制支架框架的横向定位。 又一个实施例包括多个向外偏置的臂,通过覆盖护套段保持到互补的支架框架特征。 另一个实施例将可视化系统集成在主体传送系统中。 除了显示和描述的之外,还考虑了与使用这些实施例相关联的硬件和方法的变化。
