MULTI-BEAM GENERATOR OF FOCUSED IMPACT-WAVE ACOUSTIC PULSES Russian patent published in 1998 - IPC

FIELD: medicine; biology; echo ranging. SUBSTANCE: generator has at least three flat electromagnetic radiators positioned in symmetry with generator axis. Radiators consist of flat spiral coils with metal membrane and focusing acoustic lenses, foci of which are combined at one point on generator axis. One coil lead of every radiator is connected to lead of inherent capacitive storage. Second leads of coils are interconnected and connected to one of discharge electrodes. Second leads of all radiator coils are connected to second electrode of discharge. Symmetrical arrangement of electromagnetic radiators relative to generator axis and connection of radiator coils to discharge circuit with one controlled discharge and separate capacitive storages for every radiator enhance efficiency of destruction of renal calculuses and gallstones. EFFECT: enhanced efficiency. 5 cl, 3 dwg
