Abstract: A vapor delivery needle is provided that may include any of a number of features. One feature of the energy delivery probe is that it can apply condensable vapor energy to tissue, such as a prostrate, to shrink, damage, denaturate the prostate. In some embodiments, the needle can ablate a continuous lobe region in the prostate parallel to the urethral wall. Another feature of the vapor delivery needle is that it can introduce a cooling fluid into the urethra during treatment. Methods associated with use of the energy delivery probe are also covered.

Abstract: The present disclosure concerns a delivery system for delivering a medically useful payload through the vasculature to a site of interest in the patient's body. The medically useful payload may be a therapeutic device, such as a stent, and it may be a diagnostic tool, such as an imaging device. Owing to its structural attributes, the presently-inventive delivery system is well suited for carrying medical payload to and through vessel curvature and to branched regions (i.e., bifurcations) in same. Also, the device is well-suited to traveling through a vessel over a guiding element, such as a guidewire, which itself exhibits curvature.
