Systems and methods for prostate treatment
First Claim
1. A method for treating benign prostatic hyperplasia (BPH), comprising:
- introducing an energy delivery member transurethrally into a transition zone tissue adjacent a patient'"'"'s prostatic urethra; and
injecting a condensable vapor media from the energy delivery member into the transition zone tissue at a depth of less than 12 mm outward from the patient'"'"'s prostatic urethra so as to confine the condensable vapor media in the transition zone tissue and to ablate the transition zone tissue adjacent to and less than 12 mm outward from the prostatic urethra, wherein the condensable vapor media is configured to apply energy ranging from 1 to 40 cal/sec to the transition zone tissue.

Abstract
An energy delivery probe is provided that may include any of a number of features. One feature of the energy delivery probe is that it can apply energy to tissue, such as a prostrate, to shrink, damage, denaturate the prostate. In some embodiments, the energy can be applied with a vapor media. The energy delivery probe can include a vapor delivery member configured to extend into a transition zone prostate tissue. A condensable vapor media can be delivered from the vapor delivery member into the transition zone tissue, wherein the condensable vapor media can propagate interstitially in the transition zone tissue and be confined in the transition zone tissue by boundary tissue adjacent to the transition zone tissue. Methods associated with use of the energy delivery probe are also covered.
