[Theoretical substantiation and experience in vibromechanical dilatation of hollow organs].

The paper analyzes the principle of operation of a dilatation catheter, a device designed for expanding hollow organs. The organs (blood vessels, esophagus, cervix uteri through the cervical canal, uterine tubes) were the subject of investigation. The effective energy of action on the hollow organ wall in different catheter operations and the safety index for dilatation of hollow organs were defined. The aim of the study was to theoretically substantiate the clinical potentialities of the vibromechanical hollow organ dilatation.
