USE OF MAGNETIC SUBSTANCE DURING REMOVAL OF STONES Russian patent published in 2020 - IPC A61K33/26 A61L31/02 A61B17/22 A61P13/04 

Abstract RU 2727236 C1

FIELD: medicine.

SUBSTANCE: invention can be used for application of magnetic substance when removing stones of urinary system. Magnetic substance magnetizes stone by physical adsorption or chemical bonding. After that, stone with size of 2–5 mm is removed by exposure to non-contact magnetic field. Magnetic substance is magnetic Fe3O4 nanoparticles containing carboxyl groups.

EFFECT: invention enables removing stones from the urinary system of the patient without damaging the ureter wall.
