METHOD FOR NON-INVASIVE DESTRUCTION OF BIOLOGICAL TISSUES LYING BEHIND THORACIC BONES Russian patent published in 2013 - IPC A61N7/02 A61B18/04 

FIELD: medicine.

SUBSTANCE: invention refers to medicine, namely the use of ultrasound for local thermal and mechanical effect on biological tissue in ultrasound surgery. Biological tissue is exposed to focused ultrasonic bunch of high intensity within the frequency range of 0.8-2 MHz. The ultrasonic bunch is created in the form to provide minimal ultrasound ingress into thoracic bones on the bases of pre-determination of bone coordinates. What is also used is visualisation in generation of tissue boiling in an exposure centre. The exposure is conducted at ultrasonic bunch power to provide formation of short fronts in the primary focus with peak positive pressure 30-80 MPa. Local destruction is created within the arrangement of the primary focus without involving the side foci.

EFFECT: method enables reducing an focus splitting effect onto the primary and side foci after the focused ultrasound passes through a periodical rib structure.
