ABSTRACT:
A catheter for supplying liquid to the coronary sinus in a perfusion procedure comprising a tubular catheter body having an interior lumen, a proximal end, and a distal end; and an inflatable cuff (balloon) adjacent the distal end of the catheter. The cuff has a proximal end and a distal end, each of which encircle the catheter body and hermetically seal thereto. The cuff further comprises an elongated central section having a length of at least 1 inch. When the inflated cuff is positioned a sufficient distance into the coronary sinus to firmly retain the cuff therein, it blocks the left coronary vein where it meets the coronary sinus. Further, the cuff can comprise end panels defined between the central section and the proximal and distal cuff ends. The end panels have a shape which allows for flexure between the central section and the cuffs proximal and distal ends.
