Abstract
Methods are describe for treating intraluminal locations such as in a patient's lung. The device is a catheter which has an elongated shaft with an inner lumen, preferably defined by an inner tubular member, formed of heat resistant polymeric materials such as polyimide and high temperature vapor is directed through the inner lumen into the intraluminal location to treat tissue at and/or distal to the location. The outer surface of the catheter is also formed of heat resistant material. An enlarged or enlargeable member, such as a balloon, is provided on a distal portion of the catheter shaft to prevent proximal flow of the high temperature vapor upon discharge from the catheter.
