阅读说明：本技术 用于假体心脏瓣膜装置的具有系绳的递送系统及相关联的方法 (Delivery system with tether for prosthetic heart valve device and associated methods ) 是由 M·麦克里恩 于 2018-04-17 设计创作，主要内容包括：本文公开了用于假体心脏瓣膜装置的具有系绳的递送系统和相关联的方法。根据本技术的实施例构造的递送系统可包括例如细长导管主体、由细长导管主体承载并承载人工心脏瓣膜装置的递送囊状件、以及可滑动地设置在递送囊状件内的束紧构件。递送系统还可包括多个系绳元件,这些系绳元件联接于假体装置并延伸穿过束紧构件和导管主体。系绳元件的缩回可将假体装置的至少一部分推入束紧构件的远端部分中,以重新套住假体装置的至少一部分,并在假体装置已接触天然瓣膜的组织之后,允许将假体膜装置相对于天然瓣膜重新定位。(Disclosed herein are delivery systems with tethers and associated methods for prosthetic heart valve devices. A delivery system constructed in accordance with embodiments of the present technology can include, for example, an elongate catheter body, a delivery capsule carried by the elongate catheter body and carrying a prosthetic heart valve device, and a cinching member slidably disposed within the delivery capsule. The delivery system can further include a plurality of tether elements coupled to the prosthetic device and extending through the cinching member and the catheter body. Retraction of the tether element may push at least a portion of the prosthetic device into the distal end portion of the cinching member to recapture at least a portion of the prosthetic device and allow the prosthetic membrane device to be repositioned relative to the native valve after the prosthetic device has contacted tissue of the native valve.)
