Abstract: A system for treating target tissue located at a first location along an anatomic lumen comprises a catheter including a distal end portion configured for deployment in the anatomic lumen. The system also comprises an expansion device coupled to the distal end portion of the catheter. The expansion device has an expanded size in a deployed configuration. The expansion device in the deployed configuration occludes the anatomic lumen at a second location, different from the first location, along the anatomic lumen. The expansion device also occludes at least one of a plurality of blood vessels adjacent the anatomic lumen to reduce blood flow to the target tissue at the first location.
