A delivery assembly comprises a delivery apparatus and a prosthetic valve releasably connected to a cord-retaining device of the delivery apparatus by a plurality of cords or tethers. The cords desirably have a multi-stranded construction formed from a plurality of strands of material. The multi-stranded construction can be, for example, a braided construction, a twisted construction, or a whip-stitch construction. The multi-stranded construction can include integral openings along opposing end portions of each cord. Each cord can extend through an aperture in an apex of the frame of the prosthetic valve or around an apex with one end portion of the cord being retained on the cord-retaining device and another end portion of the cord being retained on a slideable release member of the delivery apparatus. 递送组合件包括递送设备和假体瓣膜，所述假体瓣膜通过多根绳索或系绳可释放地连接至所述递送设备的绳索保持装置。所述绳索期望地具有由多股材料形成的多股构造。所述多股构造可以是例如编织构造、绞合构造、或锁缝线迹构造。所述多股构造可以包括沿每根绳索的相对端部的一体开口。每根绳索可以延伸通过所述假体瓣膜的框架的顶点中的孔口或围绕顶点延伸，其中所述绳索的一个端部保持在所述绳索保持装置上，并且所述绳索的另一端部保持在所述递送设备的
