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