摘要： This invention provides prosthesis delivery systems with tips constructed to permit both easier advance into the body and easier removal from the body after expanding the prosthesis. The tip includes a distal taper that can gently widen a lumen during advance in instances where the lumen is narrower than the tip and a proximal taper that can gently widen the lumen on retraction in instances where the prosthesis does not immediately expand the lumen to provide clearance for the larger diameter tip.

摘要： This invention provides prosthesis delivery systems with atraumatic tips that can be dislodged from the catheter so that the catheter can be easily removed from the body after expanding the prosthesis, by pulling the catheter proximally. With the tip dislodged, the catheter, which is of smaller diameter than the tip can be removed even in instances where the prosthesis does not expand the lumen to a large diameter. This invention also provides prosthesis delivery systems with a contoured protective outer sheath having smaller diameters in proximal portions that normally are acutely bent when the system is in the body, than in distal portions corresponding to the position of the prostheses. These systems are more flexible and the sheaths less likely to kink, especially when configured as part of a large delivery system.
摘要翻译： 本发明提供了具有无创伤尖端的假体递送系统，其可以从导管移出，使得在扩张假体之后，可以通过向近侧拉动导管来容易地从体内移除导管。 在尖端移动时，即使在假体不将内腔扩张到大直径的情况下，也可以去除直径小于尖端的导管。 本发明还提供了具有轮廓保护性外护套的假体输送系统，其在近端部分具有较小的直径，当系统在体内时通常会急剧弯曲，而不是对应于假体位置的远端部分。 这些系统更灵活，护套不太可能扭结，特别是当配置为大型输送系统的一部分时。

摘要： A method of forming a balloon for medical purposes comprising co-extruding in a tubular shape a base structural layer of a member selected from the group consisting oft polyamides, polycarbonates, polyesters and copolymers thereof and a heat sealable layer selected from the group consisting of polyethylene and copolymers thereof. The tubular member is then biaxially oriented by inflating the tube with a gas to a predetermined central diameter greater then the initial diameter of the tube and simultaneously heating the inflated tube to a temperature sufficient to biaxially orient the base structural layer. The member is then cooled the inflated tubular member and then elevated in temperature for a second time to the biaxially orienting temperature. The twice-heated tube is allowed to cool and the gas is withdrawn whereby the tubular member will assume a generally tubular shape and the main structural layer will remain biaxially orientated and the heat sealable layer will not be biaxially orientated.

摘要： This invention provides smooth delivery and accurate positioning of prostheses in the body. In embodiments, systems are provided that include elongate members extending generally along the axis of a supporting catheter to a free ends. The elongate members extend through openings in the prosthesis to maintain the position of the prosthesis on the catheter. The prosthesis can be released from the catheter by relative axial motion of the catheter and the elongate members such that the free ends are removed from the openings in the prosthesis. In embodiments, the elongate members hold the distal end of a self-expanding stent at a desired axial location and in radial compaction as a restraining sheath is withdrawn. The friction between the sheath and stent puts the stent under tension, which reduces the radial force on the sheath wall, allowing smoother retraction. Proximal portions of the stent radially expand and axially shorten. The distal end, however, is maintained at the desired axial location and released from the catheter to contact the body lumen wall without substantial axial shortening.

摘要翻译： 本发明提供了假体在体内的平稳输送和精确定位。 在实施例中，提供了包括通常沿着支撑导管的轴线延伸到自由端的细长构件的系统。 细长构件延伸穿过假体中的开口，以维持假体在导管上的位置。 假体可以通过导管和细长构件的相对轴向运动从导管释放，使得自由端从假体中的开口移除。 在实施例中，细长构件将自膨胀支架的远端保持在期望的轴向位置处，并且随着约束护套被拉出而将其径向压紧。 护套和支架之间的摩擦力使支架处于张力状态，从而降低了护套壁上的径向力，从而实现了更平滑的收缩。 支架的近端部分径向扩张并轴向缩短。 然而，远端保持在期望的轴向位置并且从导管释放以接触体腔壁而没有显着的轴向缩短。
