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.
Claims20
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 detect and store a series of local maxima or minima of the sensor data signal during the occlusion phase, generate a curve fit function representing an envelope curve for said series of local maxima or minima, and determine a calculated release time for the occlusion phase based upon a time derivative of the curve fit function.
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 configured to selectively activate the occlusion device for substantially occluding the coronary sinus during an occlusion phase, and to deactivate the occlusion device for substantially non-occluding the coronary sinus during a release phase,
- wherein the control system is configured to randomly select a duration time for the release phase from a predefined bracketed range of about 2 second and about 15 seconds.
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 configured to selectively activate the occlusion device for substantially occluding the coronary sinus during an occlusion phase, and to deactivate the occlusion device for substantially non-occluding the coronary sinus during a release phase,
- wherein the control system is configured to end the release phase after a release phase duration time that is from a predefined pattern of release phase duration times in a range about 2 seconds to about 6 seconds, the control system storing said predefined pattern of release phase duration times.
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 couple with a proximal portion of the coronary sinus occlusion catheter, the control system including a computer-readable memory storage device having computer-readable instructions stored thereon that, when executed by at least one processor, cause the following operations to occur:
- monitor a sensor data signal indicative of a hemodynamic performance parameter of a heart;
- selectively activate of the occlusion device for substantially occluding the coronary sinus during an occlusion phase;
- and
- deactivate the occlusion device for substantially non-occluding the coronary sinus during a release phase.
