Abstract
A thermal therapy catheter for preferentially treating tissue adjacent to a body lumen includes a catheter shaft that is insertable into the body lumen. An energy-emitting element is carried by the catheter shaft, and is operable to radiate a generally symmetrical energy pattern. The catheter shaft includes a plurality of cooling lumens around the energy-emitting element, configured for circulation of a fluid therethrough. An attenuating element is located in at least one of the plurality of cooling lumens and is arranged to modify the generally symmetrical energy pattern radiated by the energy-emitting element to deliver an asymmetrical energy pattern to the tissue adjacent to the body lumen.
