DEVICE FOR INTRAVASCULAR CARDIAC VALVE SURGERY

摘要

The invention relates to a device for the treatment of cardiac valve insufficiency or cardiac valve stenosis, which consists of a microaxial pump (40). The pump part (14) of said microaxial pump comprises a dilatation devi ce (18) which can be used to push open a stenosed valve. The dilatation device is configured as a high-pressure balloon. During dilatation the microaxial pump (40) functions in such a way that it relieves the cardiac valve. In case of cardiac valve insufficiency a stent (21) which encloses a flexible cardiac valve prosthesis (20) is fixed to the dilatation device (17).The stent (21) is pressed against the insufficient cardiac valve by dilatation so that the cardiac valve ceases to function and the cardiac valve of the cardiac valve prosthesis is unfolded and takes over the function of the natural cardiac valve.
