Abstract
The coronary sinus catheter has a balloon for occluding the coronary sinus and a lumen for delivering fluid distal to the occluding member. The catheter has a proximal portion which is relatively stiff to provide column strength to facilitate insertion, advancement and steering of the catheter. The catheter also has a distal portion which is more flexible than the proximal portion to provide an atraumatic, kink-resistant distal end. The flexible, distal portion also helps prevent damage to the coronary sinus and facilitates guiding the catheter into the coronary sinus.
