Abstract: In a method for the intermittent occlusion of the coronary sinus, in which the coronary sinus is occluded by an occlusion device, the fluid pressure in the occluded coronary sinus is continuously measured and the occlusion of the coronary sinus is released as a function of at least one parameter derived from the measured pressure values, a perfusate is introduced into the occluded coronary sinus or at least a vein running into the coronary sinus, wherein the control of the introduced amount of perfusate is performed under consideration of at least one parameter derived from the measured pressure values. The device for the intermittent occlusion of the coronary sinus includes an occlusion means for the occlusion of the coronary sinus, a control means for the triggering or release of said occlusion and a pressure measuring means for the determination of the fluid pressure prevailing in the coronary sinus during the occlusion.

Abstract: In a means for support of the performance of a heart (1) in which fluid is taken from blood vessels via an external pump (7) and is returned to the blood vessels, the amount of fluid being controlled as a function of the measured values, a catheter in the ventricle is equipped with sensors (4) for measuring the volume of fluid per unit of time. The sensors (4) are connected to an evaluation circuit in which the ratio of the diastolic volume to the systolic volume per heartbeat or unit of time, especially the output rate and/or the deviation of the volume which has been delivered by the heart per unit of time from a defined setpoint, for example the setpoint which has been computed from body-specific data for the cardiac output (HZV), is evaluated and a signal is generated. The pump (7) via which fluid is withdrawn from the ventricle is controlled depending on the generated signal.

Abstract: The coronary sinus is intermittently occluded by use of means for occluding the sinus, a pressure transducer for sensing the fluid pressure within the sinus and providing corresponding fluid pressure signals, and a controller responsive to the transducer and arranged to provide trigger signals to the occluding means to trigger an occlusion and to interrupt the occlusion, the system being characterized in that the controller is arranged to estimate a plateau level of the fluid pressure during each occlusion and for providing a trigger signal to interrupt each occlusion on the basis of the estimate. The duration of the interruption before the next occlusion is controlled in response to the volume flow in the sinus during the interruption. Pharmacological agents are injected into the sinus during the occlusion, for retroperfusion to the heart tissue. An analysis of heart function is obtained by analyzing the local pressure maxima in successive heartbeats during occlusion.
