1. A system for treating heart muscle tissue, comprising:

  • a coronary sinus occlusion catheter including a distal tip portion, a proximal hub portion, and a balloon fluid lumen, the distal tip portion of the coronary sinus occlusion catheter comprising an inflatable balloon device configured to occlude a coronary sinus when inflated with fluid via the balloon fluid lumen; and

    a control system to control the inflation and deflation of the inflatable balloon device for intermittent coronary sinus occlusion, the control system comprising a display device, a pressure signal input that receives a pressure signal indicative of coronary sinus pressure, an electrocardiogram (ECG) signal input, and a control circuit that activates a pneumatic subsystem to inflate or deflate the inflatable balloon device of the coronary sinus occlusion catheter for intermittently the coronary sinus,wherein the control system is programmed to activate the inflatable balloon device of the coronary sinus occlusion catheter to intermittently occlude the coronary sinus according to an automated, predetermined pattern of occlusion periods and release periods that is previously stored by the control system and that is independent of the pressure signal indicative of the coronary sinus pressure.
