Abstract
A catheter system for mechanical dilatation of coronary arterial stenoses includes a balloon dilatation catheter, a guide wire and a guide catheter. The balloon dilatation catheter has, for the perfusion of vessel fluid during dilatation, side openings arranged both distal and proximal of the balloon and connected to one another via a lumen extending within the balloon. The internal lumen configuration of the balloon dilatation catheter permits the catheter system to be utilized as either a 'monorail'-type or an 'over-the-wire' system.
