Method and device for the intermittent occlusion of the coronary sinus
In a method for intermittently occluding the coronary sinus, in which in an alternating manner the coronary sinus is occluded by an occlusion device and the occlusion is released, the curve of the fluid pressure occurring in the coronary sinus after the release of the occlusion is estimated by calculation and the time of the beginning of the next occlusion is determined as a function of the estimated pressure curve.
1. A device for the intermittent occlusion of the coronary sinus, comprising:
an occlusion device for the alternate occlusion of the coronary sinus and release of the occlusion, wherein the occlusion device is positioned along a distal end of a multi-lumen catheter that is insertable into in the coronary sinus of a heart via an atrium;
a device configured to detect bodily characteristic measurements including pressure maxima or pressure minima measurements occurring in the coronary sinus; and
a control device for delivering control signals that control the time of the beginning and release of the occlusion caused by the occlusion device insertable in the coronary sinus, wherein the control device is configured to estimate an envelope curve of the bodily characteristic measurements including said pressure maxima or minima measurements detected in the coronary sinus during consecutive heart beats after the release of the occlusion, wherein the control unit is configured to trigger the next occlusion of the coronary sinus caused by the occlusion device at a time determined by the control unit as a function of the estimated envelope curve of the bodily characteristic measurements.
2. The device of claim 1 , wherein the multi-lumen catheter comprises a balloon inflation lumen.
3. The device of claim 2 , wherein the balloon-inflation lumen receives fluid from a fluid pumping system.
4. The device of claim 3 , wherein the control unit delivers control signals for stopping and starting the fluid pumping system so as to control occlusions of the coronary sinus by the occlusion device.
5. The device of claim 1 , wherein the device configured to detect the bodily characteristic measurement occurring in the coronary sinus comprises a pressure measuring device positioned proximate to the distal end of the multi-lumen catheter.
6. The device of claim 5 , wherein pressure values detected by the pressure measuring device are stored in a memory that stores data indicative of the estimated pressure curve.
