SYSTEMS AND METHODS FOR GENERATING EXPOSURE ON TARGET TISSUE WITH USING MICROWAVE ENERGY Russian patent published in 2014 - IPC A61B18/18 A61N5/02 A61F7/00 

FIELD: medicine.

SUBSTANCE: invention refers to agents for non-invasive microwave energy supply in therapy. A system for microwave energy application to a tissue comprises a signal generator at a frequency within the range of 5 GHz and 6.5 GHz, an irradiator comprising one or more microwave antennas, and a contact area with the tissue with the microwave antenna configured to emit polarised electromagnetic radiation so that an electrical field component of electromagnetic radiation is parallel with the outer layer of skin, a vacuum source coupled with the contact area with the tissue, a cooling source and a controller configured to control the signal generator, vacuum source and cooling source. The system can comprise a fluid chamber arranged between the microwave antenna and the tissue, and a cooling plate between the cooling chamber and the tissue. Also, the system can be presented to generate an energy loss density profile which has a peak energy loss density within a layer of the target tissue. In the microwave energy supply device in the system, a cooling fluid between a cooling element and a microwave energy supply unit has a dielectric constant greater than that of the cooling element. According to the other version, the device comprises a vacuum chamber configured to lift the tissue with the target area, and contacting the tissue with the cooling plate with the cooling plate presented to contact the skin surface above the target area, to cool the skin surface and to separate the skin tissue from the microwave energy supply unit. In a damage formation system, in the first tissue layer, microwave energy from the antenna forms a damage extending within the peak energy loss. According for the other version, a vertical wave structure is generated in the first layer with a distance from a peak constructive interference to the skin surface being more than a distance from the peak constructive interference to an interface of the first and second layers. In a temperature increase system of at least a part of the tissue structure below the interface of a dermal layer and a sub-dermal layer, there is an energy supply unit and a unit for heat removal from the skin surface and at least a part of the upper dermal layer.

EFFECT: using the invention enables to extend the range of aids for microwave therapy.
