| 摘要 |
The present invention relates to a delivery system for a self-expanding stent. The delivery system comprises an inner member having a distal end, the inner member being configured to retain a self-expanding stent proximate the distal end, the inner member including a first marker band (64) such that, when the self-expanding stent is retained proximate the distal end, the first marker band (64) is disposed between a distalmost leading end of the self-expanding stent and a trailing end of the self-expanding stent, wherein the marker band indicates a reconstrain limit of a partially-expanded, self-expanding stent;
an outer member positioned about the inner member, the outer member being slidable relative to the inner member in an axial direction;
a holding sleeve positioned such that, when the self-expanding stent is retained proximate the distal end, the holding sleeve is within an interior of the stent and cooperates with the outer member so as to retain the positioning of the stent; and
an inflatable device positioned about the inner member, wherein the inflatable device is disposed between the holding sleeve and the distal end of the inner member. |
