    • In one aspect, a stent delivery system includes a catheter having two or more pullwire lumens evenly spaced about the central axis of the catheter and thereby balanced within the catheter. Pullwires are positioned in the pullwire lumens. Proximal portions of the pullwires are attached to a connector, which is attached to a master pullwire. The connector has a given range of motion that allows the pullwires to move within the pullwire lumens, thereby ensuring full flexibility of the catheter. The pullwires assume different lengths. A pullwire positioned over the outer curve of a flexed catheter may be longer than a pullwire positioned within the inner curve of the catheter, preventing the catheter from being straightened or displaced by the action of retracting the pullwires. The catheter may serve as either an inner member on which a stent is mounted or a sheath enclosing a stent.
    • 在一个方面,支架输送系统包括具有两个或更多个拉丝管腔的导管,所述拉线管腔围绕导管的中心轴线均匀隔开,从而在导管内平衡。 拉线位于拉线管内。 拉线的近端部分附接到连接到主拉线上的连接器。 连接器具有给定的运动范围,其允许拉线在拉丝内管内移动,从而确保导管的完全柔性。 拉线假设不同长度。 位于弯曲导管的外曲线上方的拉线可以比位于导管内曲线内的拉线更长,从而通过收回拉线的动作来防止导尿管变直或变位。 导管可以用作安装支架的内部构件或者围绕支架的护套。
