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.

System for treating unwanted tissue

A device positionable in a cavity of a bodily organ (e.g., a heart) may discriminate between fluid (e.g., blood) and non-fluid tissue (e.g., wall of heart) to provide information or a mapping indicative of a position and/or orientation of the device in the cavity. Discrimination may be based on flow, or some other characteristic, for example electrical permittivity or force. The device may selectively ablate portions of the non-fluid tissue based on the information or mapping. The device may detect characteristics (e.g., electrical potentials) indicative of whether ablation was successful. The device may include a plurality of transducers, intravascularly guided in an unexpanded configuration and positioned proximate the non-fluid tissue in an expanded configuration. Expansion mechanism may include helical member(s) or inflatable member(s).

Medical device for use in bodily lumens, for example an atrium

An intra-cardiac mapping system is based on locating the ports through which blood flows in or out the heart chambers. For many procedures, such as ablation to cure atrial fibrillation, locating the pulmonary veins and the mitral valve accurately allows to perform a Maze procedure. The location of the ports and valves is based on using the convective cooling effect of the blood flow. The mapping can be performed by a catheter-deployed expandable net or a scanning catheter. The same net or catheter can also perform the ablation procedure.

Apparatus and method for intra-cardiac mapping and ablation

An elastic structure is introduced percutaneously into the left ventricle and attached to the walls of the ventricle. Over time the structure bonds firmly to the walls via scar tissue formation. The structure helps the ventricle expand and fill with blood during the diastolic period while having little affect on systolic performance. The structure also strengthens the ventricular walls and limits the effects of congestive heart failure, as the maximum expansion of the support structure is limited by flexible or elastic members.

System for improving diastolic dysfunction

The invention can selectively heat a diseased area in the lung while minimizing heating to the healthy area and surrounding tissue. This is 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 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 is switched in a way it always passes through lungs but only intermittently passes through adjacent organs. If heat activated drugs are present in the lungs, they are selectively released in the heated tissue.
