Patent ID: 8790265

Claim:
A system for the intermittently occluding a coronary sinus in a heart, comprising: a multi-lumen catheter having an occlusion device along a distal end configured to be inserted into a coronary sinus of a heart via an atrium, wherein the occlusion device along the distal end of the multi-lumen catheter is intermittently adjustable to substantially occlude the coronary sinus of the heart; a pressure measuring device connected to the multi-lumen catheter, the pressure measuring device being configured to measure a fluid pressure in the occluded coronary sinus when the occlusion device occludes of the coronary sinus, and the pressure measuring device being 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 control circuitry configured to cause a release of the occlusion of the coronary sinus, wherein the control circuitry is configured to determine a pressure increase and/or pressure decrease per time unit while the coronary sinus is occluded by the occlusion device and configured to cooperate 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 unit.
