Abstract
A balloon dilatation catheter used for percutaneous transluminal coronary angioplasty includes an inner tube and an outer tube. The anchor joint of the inner tube and outer tube is permit distal movement of the inner tube with respect to the outer tube while precluding proximal movement of the inner tube with respect to the outer tube. The outer tube is not immovably secured to the inner tube but, rather, may be slidably disposed on the inner tube. The distal end of the outer tube may be tapered to reduced diameter that permits the tapered portion to move longitudinally with respect to the inner tube. The inner tube is provided with an abutment member against which an abutment surface to the outer tube may abut.
