Embodiment Construction

[0171] Throughout the following description, specific details are set forth in order to provide a more thorough understanding of the present invention. However, the invention may be practiced without these details. In other instances, well known elements have not been shown or described in detail to avoid unnecessarily obscuring the invention. Accordingly, the specification and drawings are to be regarded in an illustrative rather than a restrictive sense.

[0172] Methods and apparatus according to certain embodiments of the present invention may be applied to selectively heat diseased tissue regions of a patient while minimizing heating of other tissue of the patient. Heating can be achieved by exposing the diseased tissue to an electromagnetic field to induce dielectric or eddy current heating. Electromagnetic fields may include radio frequency (RF) energy. In some embodiments, the RF energy includes microwave radiation.

[0173]By applying electromagnetic energy, selec...

Abstract

The invention may be applied to selectively heat a diseased area in the lung while minimizing heating to the healthy area and surrounding tissue. This can be done by exposing the lung to an electromagnetic field causing dielectric or eddy current heating. The invention is particularly useful for treating emphysema as the diseased areas in emphysema patients have reduced blood flow. The diseased area will heat up rapidly while the healthy tissue will be cooled by the blood flow. This is particularly effective for treating emphysema because of the low mass of the lungs and the high blood flow. To avoid heating of surrounding organs the direction of the electromagnetic energy may be switched in a way it always passes through lungs but only intermittently passes through adjacent organs.
