Method for introducing cardioplegia solution into the coronary sinus
First Claim
1. A method for administering cardioplegia solution into the coronary sinus of a heart comprising the steps of:
- providing a catheter having a tubular catheter body with a proximal end, a distal end, a first lumen extending between the proximal and distal ends, an inflatable cuff adjacent the distal end, and a radially expandable stop provided proximally from the cuff;
radially expanding the stop;
inserting the distal end of the catheter into the coronary sinus until the stop abuts heart wall;
inflating the cuff to substantially seal the coronary sinus; and
injecting cardioplegia solution into the coronary sinus through the first lumen.

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.
