Abstract
A device and method for treating intraluminal tissue employ an inflatable member having a plurality of heating zones adapted for selective activation, whereby one or more of the heating zones can be activated, by one or more energy sources, to deliver heat to selected intraluminal tissue. The inflatable member can be a balloon that is attached to a catheter having a plurality of passageways for delivering fluids (i.e., liquid or air) to internal chambers of the balloon, thereby inflating the balloon. Each energy source is positioned within a corresponding chamber and may be any one of various types, including a piezoelectric cylinder, a microwave antenna, a cylindrical RF (radio-frequency) source, or a resistive heating coil.
