ABSTRACT:
An interventional catheter for angioplasty and the like, comprising a catheter tube formed of two superposed layers of materials different from one another. The inner layer is comprised of a low friction nonkinkable material to avoid risk of clogging of a guide wire in the longitudinal lumen. The outer layer is comprised of a material with higher friction coefficient than the material forming the inner layer. The balloon is welded at its distal end to the outer layer of the catheter tube. The proximal end of the balloon is welded to a tube surrounding the catheter tube.
