Abstract
A diversion catheter for use during ablation procedures includes a distal occlusion device such as a diversion balloon. The diversion balloon blocks blood flowing through a cardiac vein. The diversion catheter employs ports proximal and distal to the diversion balloon. The proximal and distal ports are in fluid communication so that blood flow through the cardiac vein is diverted through the distal and proximal ports and away from a cardiac surface intended for ablation.
