摘要： A method and apparatus for delivering a stent (205), including, but not limited to, a self-expanding stent, into a body lumen. The apparatus (200) comprises an outer tube (203) having a proximal end and a distal end and sized to hold a stent (205) therein in a radially constricted condition, an inner tube (201) within the outer tube (203) and having a proximal end and a distal end, and a holding element (207) comprising one or more inflatable balloons carried on the inner tube (201) at the location of the loaded stent. The balloon (207) can be inflated prior to the procedure so that the bottom (207) presses against the inner surface of the outer tube (203) trapping the stent in its longitudinal position between the inner (201) and outer (203) tubes. Accordingly, the outer tube (203) can be slid proximally to release the stent (205) or distally to retract the stent (205) back into the delivery device (200) without the stent inadvertently sliding.

摘要翻译：本发明是用于将支架（包括但不限于自扩张支架）输送到体腔中的方法和装置。该装置包括外管，该外管具有近端和远端，并且其尺寸适于将支架保持在径向收缩的状态中，内管内管并具有近端和远端，并且保持元件包括一个或更多的充气气球承载在内管上，在加载的支架的位置。气囊可以在手术之前充气，使得球囊压靠外管的内表面，将外支管的内表面捕获在内管和外管之间的纵向位置。因此，外管可以向近侧滑动以释放支架或远端以将支架缩回到输送装置中，而不会使支架无意中滑动。
