Abstract: An implant release mechanism for releasing, for example, a stent (60) is provided with three restraining wires (62) which pass in the space between a wire guide catheter (24) and a pusher sheath or dilator (30) and are arranged substantially equi-angularly threrearound. Each restraining wire (62) holds both the proximal and distal ends of the stent (60), in this case each holding a proportion of the ends of the stent (60). When the restraining wires (62) are pulled they will first unwrap from the proximal end of the stent (60) and will then release the distal end of the stent (60) so as to allow the stent to become fully deployed within the lumen of the patient. The use of common release wires improves deployment of implants and reduces the number and volume of components in the device, thereby allowing it to occupy a smaller volume.

Abstract translation: 用于释放例如支架（60）的植入物释放机构设置有三条限制线（62），其限制在导线导管（24）和推动器护套或扩张器（30）之间的空间中，并且基本上布置 平等的三分之一。 每个限制线（62）保持支架（60）的近端和远端，在这种情况下，每个限制线都保持支架（60）的端部的一部分。 当约束线（62）被拉动时，它们将首先从支架（60）的近端展开，然后释放支架（60）的远端，以便使支架完全展开在 患者。 使用常见的释放线可改善植入物的部署，并减少装置中部件的数量和体积，从而使其占据较小的体积。
