Balloon catheter

摘要

A balloon (60) is attached to a catheter tube (62). A stiffening wire (64) extends from the catheter tube (62) to a tip (66). A lumen (70) is provided at the end of a flexible tube that at its opposite end is attached to the catheter tube (62). When the balloon (60) is deflated, the tube (72) is straight. When the balloon (60) is inflated, the tube (72) bends around the balloon (60).
