Claim Text:
1. A method of using a coronary sinus occlusion catheter, comprising: engaging an inflatable balloon device of a distal tip portion of the coronary sinus occlusion catheter with an interior wall of the coronary sinus while the inflatable balloon device is in an inflated condition, detecting a first pressure at a first pressure sensor lumen that extends to a distal position that is distal of the inflatable balloon device; detecting a second pressure at a second pressure sensor lumen that extends to a proximal position that is proximal of the inflatable balloon device for detecting a second pressure; and determining a blood flow rate of blood passing along the distal tip portion in the coronary sinus from a region distal of the balloon device to a region proximal of the balloon device by comparing the first pressure detected at the first pressure sensor lumen and the second pressure detected at the second pressure sensor lumen.
