Abstract

A retrograde coronary sinus perfusion device provides steady state blood flow to the coronary sinus and has a balloon set back from the catheter tip to block the coronary sinus during most of diastole to maximize retrograde perfusion. A global device seals the coronary sinus at the coronary sinus valve.
