1. An apparatus to heat tissue useful in the treatment of emphysema or COPD, the apparatus comprising:
a heating energy signal generator;
one or more electromagnetic energy signal applicators connected to receive an output signal from the heating energy signal generator and operative to couple electromagnetic energy from the heating energy signal generator into tissue of a body, the one or more electromagnetic energy signal applicators comprising one or more signal applicators selected from the group consisting of: electrodes, coils and antennas; and
a controller connected to receive a temperature signal indicative of a temperature of the tissue at one or more locations within the body wherein the controller is configured to regulate heating energy delivered into the body from the heating energy signal generator based at least in part on the temperature signal; and
the controller comprises a thermal model of at least a portion of the body, the thermal model correlating temperature at one of the one or more locations to temperature of a location of interest spaced apart from the one or the one or more locations and the controller is configured to apply the thermal model using the temperature signal as an input and to regulate the heating energy based at least in part on an output of the thermal model.
