FIELD: medical engineering. SUBSTANCE: device has the first clamping part and the second clamping part set to enable them to move towards each other and in the opposite direction. The parts have recesses determining canal for receiving tube pressing the stent and having longitudinal opening. The stent is brought through the longitudinal opening of the tube pressing the stent and then balloon catheter is moved into the longitudinal opening of the stent. The first and the second clamping parts are moved towards each other and pressure is produced and applied to the external tube surface pressing the stent and causing the internal diameter of the longitudinal opening to become less, to create pressure applied to the external stent surface and to press the stent against the balloon. EFFECT: uniform stent expansion. 14 cl, 20 dwg
