Abstract
An apparatus and a method to treat a disease process in a luminal structure. A dual-balloon catheter for treating a disease process in a luminal structure of a patient comprises an inner balloon, an outer balloon substantially concentric with and substantially surrounding the inner balloon, an inner balloon fluid delivery lumen in fluid connection with the inner balloon, and an outer balloon fluid delivery lumen in fluid connection with the outer balloon.
