    摘要: A dilatation balloon catheter is disclosed with an inelastic balloon wrapped about a smaller section of a guidewire. During introduction across a region of a stenosis, the balloon is wrapped around a guidewire in such a way that the guidewire contained therein can rotated freely, but cannot advance independently of the balloon. The wrapped configuration is maintained by means of a temporary bond. Inflation of the balloon, following proper positioning of the catheter breaks the bond, permitting the balloon to unwrap from the guidewire contained therein. Typically, the distal end of the guidewire is tapered and the guide wire is controllably clamped to the catheter for advancement into the patient.
