SYSTEMS AND METHODS FOR PROSTATE TREATMENT

摘要

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 vapor delivery needle can be advanced a pre-determined distance into the prostate by an actuation mechanism. The actuation mechanism can comprise, for example, a spring, or at least one magnet. Methods associated with use of the energy delivery probe are also covered.

主权项

1. A prostate treatment device, comprising:
an introducer shaft sized and configured for transurethral access into a patient; a vapor generator configured to generate a condensable vapor; a vapor delivery needle in communication with the vapor generator and slidably disposed within the introducer shaft; and a magnetic actuator configured to apply magnetic force to the vapor delivery needle to move the vapor delivery needle between a retracted position inside the introducer shaft and an extended position at least partially outside of the introducer shaft.
