Abstract:
1. A method for the intermittently occluding a coronary sinus in a heart, comprising: inserting a multi-lumen catheter having an occlusion device along a distal end into a coronary sinus of a heart via an atrium; occluding the coronary sinus of the heart with the occlusion device along the distal end of the multi-lumen catheter, wherein the multi-lumen catheter is connected to a pressure measuring device that measures a fluid pressure in the occluded coronary sinus when the occlusion device occludes of the coronary sinus, and the pressure measuring device is in communication with a memory that stores data indicative of a fluid pressure curve as a function of time based upon the measured fluid pressure in the occluded coronary sinus when the occlusion device occludes the coronary sinus; and releasing the occlusion of the coronary sinus caused by the occlusion device in response to control circuitry that determines a pressure increase and/or pressure decrease per time unit while the coronary sinus is occluded and that cooperates with the occlusion device to release the occlusion of the coronary sinus based at least in part on the pressure increase and/or pressure decrease per time.
