The generator can be disposed in a medical device to treat tissue with vapor. One feature of the medical device is that it can apply condensable vapor energy to tissue, such as a prostrate, to shrink, damage, denaturate the prostate. Methods associated with use of the vapor generator are also covered.

Abstract: A vapor delivery system and method is provided that includes a number of features. In one embodiment, a method comprises inserting a vapor delivery needle into tissue of a patient, activating a flow of vapor from a vapor generator through vapor delivery ports of the vapor delivery needle to cause condensed liquid to exit vapor delivery ports of the vapor delivery needle, generating vapor in the vapor generator, delivering a dose of vapor through the vapor delivery ports of the vapor delivery needle into the tissue, and after the dose of vapor is delivered, re-activating the flow of vapor from the vapor generator through the vapor delivery ports of the vapor delivery needle to prevent a vacuum from forming in the vapor delivery needle. Vapor therapy systems are also provided.
