| description | The invention is directed to a catheter assembly and the method for forming the same. The catheter includes an elongated shaft having proximal and distal sections, and further includes an inflatable balloon on a portion of the distal shaft section and in surrounding relation thereto. The balloon has proximal and distal tapered regions and an intermediate region longitudinally disposed therebetween. The proximal and distal tapered regions each has a first end adjacent the intermediate region and a second end opposite the first end. The wall thickness of the proximal and distal tapered regions, may, increase from the first end to the second end. A fluid-tight bond is formed between the catheter shaft and at least a section of at least one of the proximal and distal tapered regions at the second end thereof. The bond is preferably a fusion bond. At least a portion of the either or both the proximal and distal tapered regions in the bond interface is at least partially crystalline. Preferably, the crystallinity at the interface is greater than the crystallinity of the starting material from which the balloon is formed. |
