Abstract

Abstract For the treatment of an insufficient cardiac valve or a cardiac valve with a stenosis, a device is provided that comprises a micro axial pump ( 40 ). The pump portion ( 14 ) of the micro axial pump carries a dilating device ( 18 ) suitable for pushing open a stenosis in a valve. The dilating device is designed as a high-pressure balloon. During dilation, the micro axial pump ( 40 ) operates so that the heart is relieved. With insufficient cardiac valves, a stent ( 21 ) is fastened to the dilating device ( 17 ), the stent surrounding a flexible cardiac valve prosthesis ( 20 ). By dilation, the stent ( 21 ) is pressed against the insufficient cardiac valve and the same is passivated. The cardiac valve of the cardiac valve prosthesis is unfolded to assume the function of the natural cardiac valve.
