    Abstract: According to aspects described herein, there is disclosed an improved hot balloon catheter delivery system for shape memory tubular stents. An outer sheath is provided on the delivery system that facilitates stent placement on a balloon during delivery through an endoscope. In one embodiment, the stent may be positioned between radiopaque markers/electrodes and the balloon may be heated. The stent may be prevented from moving proximally relative to the catheter as the delivery system is tracked through the patient's anatomical passageways. The outer sheath may be positioned to ride over the proximal cone of the hot balloon catheter and abut the proximal end of the stent to facilitate proper alignment of the balloon for deployment. Upon deployment of the stent in an appropriate position, the sheath may be pulled away from the stent to expose the proximal cone of the balloon and thereby allow balloon and stent expansion.

    Abstract translation: 根据本文描述的方面，公开了一种用于形状记忆管状支架的改进的热球导管递送系统。 在输送系统上设置有外鞘，其在通过内窥镜输送期间便于支架置于球囊上。 在一个实施例中，支架可以位于不透射线的标记/电极之间，并且球囊可以被加热。 当通过患者的解剖通道跟踪输送系统时，可以防止支架相对于导管向近侧移动。 外护套可以被定位成骑在热气球导管的近端锥体上并邻接支架的近端，以促进球囊的适当对准以进行展开。 在将支架展开在适当的位置时，护套可被拉离支架以露出气囊的近端锥体，从而允许气囊和支架膨胀。
