Abstract
A method and apparatus are provided for the intermittent occlusion of a coronary sinus. The method includes occluding the coronary sinus with an occlusion device, continuously measuring the fluid pressure in the occluded coronary sinus and defining measured pressure by use, releasing the occlusion of the coronary sinus as a function of at least one parameter derived from the measured pressure values, introducing a perfusate into the occluded coronary sinus or at least a vein running into the coronary sinus, and controlling an amount of perfusate introduced as a function of the at least one parameter derived from the measured pressure values. The at least one parameter may be a derivative of a fluid pressure curve according to time, and/or a plateau value of the pressure minima, and/or a pressure value of the pressure maxima, of consecutive heartbeats that is computationally estimated from the measured fluid values.
