Claims
- 1. A catheter for supplying perfusion liquid to the coronary sinus, comprising:
- a tubular catheter body having an interior lumen, a proximal end, and a distal end;
- an inflatable cuff on the catheter body adjacent to the distal end thereof; and
- a stop on the catheter body, the stop being formed of flexible material in a configuration to extend radially outwardly from the catheter body in a relaxed condition and spaced a predetermined distance proximally from the cuff, the distance being so measured that when the distal end of the catheter is inserted into the coronary sinus until the stop abuts the heart muscle surrounding the opening of the coronary sinus, the cuff will be correctly disposed within the coronary sinus.
- 2. A catheter according to claim 1 including a second lumen formed in the catheter body and a thread extending through the second lumen and attached to a radially outward portion of the stop to draw the stop upon application of tension to the thread into a configuration of smaller radial dimension than that of the stop in the relaxed configuration thereof.
