Abstract:
Apparatus, systems, and methods are provided for the generation and control of energy delivery in a dosage to elicit a therapeutic response in diseased tissue. A balloon catheter can have electrodes attached to a power generator and controller such that the balloon and electrodes contact tissue during energy treatment. Energy selectively may be applied to tissue based on measured impedance to achieve gentle heating. Calibration of the apparatus and identification of attached accessories by computing the circuit impedance prior to energy dosage facilitate regulation of power delivery about a set point. Energy delivery can be controlled to achieve substantially uniform bulk tissue temperature distribution. Energy delivery may beneficially affect nerve activity.
