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。
