1. A system for minimally invasive therapy modification of tissue to be treated in a localized prostate therapy procedure in a patient, comprising:

  • an energy source configured to deliver sufficient energy into a region of target tissue associated with a prostate in the patient to provide a therapeutic result;

    an elongated shaft having at least one lumen extending therethrough;

    inflatable means coupled to an end of said shaft for separating the target tissue from a region of adjacent tissue associated with a rectum in the patient and that is located adjacent to the target tissue, and also for substantially isolating the adjacent tissue from the energy delivered from the energy source and into the target tissue; and

    wherein the tissue effects on the adjacent tissue from the energy delivered into the target tissue from the energy source are substantially modified by the inflatable means.
