Abstract
Official abstract text for this publication.
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.
First claim
Opening claim text (preview).
What is claimed is: 1. A method for treating benign prostatic hyperplasia (BPH), comprising: introducing a vapor delivery member into at least one selected location in transition zone tissue of a prostate; and injecting a condensable vapor media from the vapor delivery member into the transition zone tissue so as to ablate transition zone tissue adjacent a urethra without ablating transition zone tissue adjacent a fibromuscular stroma. 2. The method of claim 1 wherein the condensable vapor media is injected for an interval of 20 seconds or less. 3. The method of claim 1 wherein the condensable vapor media is injected at a pressure ranging from about 1 psi to 5 psi. 4. The method of claim 1 wherein the vapor delivery member is introduced transversely relative to a urethra. 5. The method of claim 1 wherein the condensable vapor media is injected in a plurality of selected locations in the transition zone tissue. 6. The method of claim 1 wherein the vapor delivery member is introduced into the transition zone tissue through a wall of a urethra from a trans-urethral probe. 7. The method of claim 1 wherein a pressure of the condensable vapor media introduction is controlled by a computer controller.
