Abstract
Some embodiments of a system or method for treating heart tissue can include a control system and catheter device operated in a manner to intermittently occlude a heart vessel for controlled periods of time that provide redistribution of blood flow. In particular embodiments, the system and methods may be configured to monitor at least one input signal detected at a coronary sinus and thereby execute a process for determining a satisfactory time period for the occlusion of the coronary sinus. In further embodiments, after the occlusion of the coronary sinus is released, the control system can be configured to select the duration of the release phase before the starting the next occlusion cycle.
Claims19
A system for treating a heart, the system comprising:
- a coronary occlusion catheter including a heart vessel occlusion balloon to occlude venous blood flow from a heart vessel into a right atrium;
- an external control console connectable with the coronary occlusion catheter to selectively inflate the heart vessel occlusion balloon for occluding the heart vessel during an occlusion phase and to deflate the heart vessel occlusion balloon for substantially non-occluding the heart vessel during a release phase,
- wherein the external control console includes:
- a controller configured to control the occlusion phase and the release phase, at least one sensor signal input to receive a hemodynamic sensor data signal from the coronary occlusion catheter, and a graphical user interface configured to simultaneously display a blood pressure numeric value, a heart rate numeric value, an occlusion phase time period, and a release phase time period,
- wherein the controller is configured to randomly select a duration time for the release phase from a predefined bracketed range of about 2 seconds and about 15 seconds, and
- wherein the controller is configured to automatically deflate the heart vessel occlusion balloon in response to detecting a hemodynamic sensor signal above a threshold value.
