TLDR
An adjustable-length balloon dilatation catheter apparatus and a method for using the same are disclosed wherein an adjustable sheath is externally manipulated to partially surround and contain the balloon segment of the catheter as mentioned in this paper.Abstract:
An adjustable-length balloon dilatation catheter apparatus and a method for using the same are disclosed wherein an adjustable sheath is externally manipulated to partially surround and contain the dilatation balloon segment of the catheter while the catheter and balloon segment are in situ during a treatment procedure. By sliding the sheath forward or backward to expose a predetermined length of the balloon segment prior to inflating the balloon, the catheter apparatus of this invention is useful in medical procedures requiring balloons of varying lengths.read more
