Abstract

A catheter with an aorta-occluding balloon comprises a tube 1 extending between its L-shaped distal end 8 and its proximal end 9, and having a main lumen 2 formed centrally of the tube, a first and second subordinate lumens 3 and 4, both of them extending longitudinally through the tube's periphery, and a balloon 5 secured to and around the tube's distal end 8. The first lumen 3 has at its end near the proximal end 9 a connector 6 for receiving a balloon-expanding means, and the second lumen 4 also has at its end near the proximal end 9 a further connector 7 for receiving a solution-feeding means. The catheter is thus designed to occlude a calcified blood vessel so that its intima may not be injured, and a fluid such as a protective solution can be supplied to the cardiac muscle through the coronary artery.
