Abstract
Methods and systems for determining patient specific treatment parameters for delivering vapor to the lung to treat lung tissue. In some embodiments vapor is delivered to the lung to cause coagulative necrosis, inducing fibrosis and thereby reducing the volume of at least one segment of the lung. The delivery parameters can be adjusted depending on the desired degree of injury to be induced in the lung tissue.
Claims17
A method of applying energy to tissue of a patient's lung to reduce the volume of the lung, the method comprising:
- identifying at least one region of lung including the lung tissue to be treated;
- inserting a delivery device into the lung region;
- delivering vapor through the delivery device to the lung tissue to be treated at a dose between about 5 calories/gram to about 40 calories/gram, wherein the vapor undergoes a phase change to liquid, and energy released during the phase change is transferred to the lung tissue to injure the tissue.
