System And Method For Treating Heart Tissue

摘要

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.

1. A system for treating heart muscle tissue, comprising:
a coronary sinus occlusion catheter including a distal tip portion comprising an adjustable occlusion device; and a control system to selectively activate the occlusion device for substantially occluding the coronary sinus during an occlusion phase, the control system being configured to couple with a proximal portion of the coronary sinus occlusion catheter, and the control system including a sensor signal input to receive a sensor data signal indicative of a hemodynamic performance parameter of a heart; and wherein the control system is configured to determine a calculated release time in response to stored data points of the sensor data signal during the occlusion phase, wherein the control system is configured to determine a filtered release time value that is based at least partially upon the calculated release time and at least one previous release time value for at least one previous occlusion phase.
