Claim 11

The use of a catheter having the form of a hollow tube (6) comprising a balloon and three lumina, said balloon being attached to the tube near its end destined to be inserted into either the vena cava or the aorta of a human or a warm-blooded animal and being inflatable from the other end of the tube (6) through one of said lumina in the tube, a second lumen in the tube being provided with at least one opening in the terminal part of the tube located beyond the balloon for transport of blood through the catheter tube, and a third lumen in the tube being provided with at least one opening located in front of the balloon for transport of cardioplegic liquid through the catheter tube, for the manufacture of a surgery expedient for use in cardiovascular surgery to direct the blood stream to by-pass the heart (1) through an extracorporeal trajectory (15) and to deliver cardioplegic liquid to the heart.

Claim 12

The use of a catheter having the form of a hollow tube (6) comprising a balloon and three lumina, said balloon being attached to the tube near its end destined to be inserted into either the vena cava or the aorta of a human or a warm-blooded animal and being inflatable from the other end of the tube (6) through one of said lumina in the tube, a second lumen in the tube being provided with at least one opening in the terminal part of the tube located beyond the balloon for transport of blood through the catheter tube, and a third lumen in the tube being provided with at least one opening located in front of the balloon for transport of cardioplegic liquid through the catheter tube, for the manufacture of a surgery expedient for use in cardiovascular surgery to direct the blood stream to by-pass the heart (1) through an extracorporeal trajectory (15) and to deliver cardioplegic liquid to the heart.
