Abstract
An angioplasty procedure wherein a balloon dilatation catheter is movably positioned within an anchoring catheter and which in turn is located within a guiding catheter or wherein a balloon dilatation catheter is movably positioned within a guiding catheter and the anchoring catheter in turn is positioned on the external surface of the guiding catheter, or wherein a balloon dilatation catheter is movably positioned within a catheter which serves both as a guiding catheter and anchoring catheter. Additionally, valve elements are attached to the guiding and anchoring catheters to provide points of securement between the catheters and the balloon dilatation catheter and to prevent the backflow of blood through the catheter assembly. Actuation of the valve elements allows a doctor to control the movement of the catheters.
