Abstract
A thermal therapy catheter includes a catheter shaft having an outer surface that is insertable into the body lumen. The catheter shaft carries an energy-emitting element. A multi-lobe balloon is positioned around the outer surface of the catheter shaft adjacent to the energy-emitting element, with opposing ends of the multi-lobe balloon being sealingly connected to the catheter shaft to form a chamber between the multi-lobe balloon and the outer surface of the catheter shaft. Fluid is circulated between the outer surface of the catheter shaft and the multi-lobe balloon in a defined fluid flow path to firmly contact the wall of the body lumen and thereby cool the body lumen tissue while thermally treating targeted tissue at a depth from the body lumen wall.
