Abstract
A vapor delivery system and method is provided that is adapted for treating prostate tissue. The vapor delivery system includes a vapor delivery needle configured to deliver condensable vapor energy to tissue. In one method, the vapor delivery system is advanced transurethrally into the patient to access the prostate tissue. The vapor delivery system is properly positioned by measuring and advancing the system based on a field-of-view of an endoscope or camera disposed within the system.
