Abstract
In a method for intermittently occluding the coronary sinus, in which the coronary sinus is occluded using an occlusion device, the fluid pressure in the occluded coronary sinus is continuously measured and stored, the fluid pressure curve is determined as a function of time, and the occlusion of the coronary sinus is triggered and/or released as a function of at least one characteristic value derived from the measured pressure values. The pressure increase and/or pressure decrease per time unit each occurring at a heart beat are used as characteristic values.

A system for intermittently occluding a coronary sinus in a heart, comprising:
- a multi-lumen coronary sinus occlusion catheter including:
- means for occluding a coronary sinus positioned along a distal end of the catheter, and
- means for fluidly communicating with the means for occluding to controllably expand and collapse the means for occluding within the coronary sinus;
- a pressure sensor connected to the multi-lumen coronary sinus occlusion catheter so as to measure a coronary sinus pressure while the means for occluding is expanded in the coronary sinus;
- and
- a controller that, in response to a comparison of a threshold value to a calculated value including a change in coronary sinus pressure per time unit while the means for occluding is expanded in the coronary sinus, causes the means for occluding to collapse and thereby release of an occlusion of the coronary sinus.
A system for intermittently occluding a portion of a coronary venous system in a heart, comprising:
- a coronary occlusion catheter including:
- means for occluding the portion of the coronary venous system positioned along a distal end of the catheter, and
- means for fluidly communicating with the means for occluding to controllably expand and collapse the means for occluding within the portion of the coronary venous system;
- a pressure sensor connected to the coronary occlusion catheter so as to measure a pressure at the portion of the coronary venous system while the means for occluding is expanded in the portion of the coronary venous system;
- and
- a controller that, in response to a comparison of a threshold value to a calculated value including a change in pressure per time unit while the means for occluding is expanded in the portion of the coronary venous system, causes the means for occluding to collapse and thereby release of an occlusion of the portion of the coronary venous system.
