The invention relates to an interventional
aortic valve stent system with an inflating type ball bag. The interventional
aortic valve stent system with the inflating type ball bag comprises a flexiblecylindrical
aortic valve stent, a ring-shaped valve ring and the ball bag; the aortic valve stent is anchored on the inner wall of an
aorta; the valve ring is arranged in the aortic valve stent, thecenter line of the valve ring and the center line of the aortic valve stent are superposed, and the outer wall of the valve ring is connected and fixed to the inner wall of the aortic valve stent; theend, which is away from the aortic valve, of the valve ring is connected with an elastic ball cage, and the ball bag is arranged in the ball cage; and under the effect of
blood pressure difference, and the ball bag moves between the top of the ball cage and the valve ring until part of the ball bag extends into the valve ring and is attached to the inner wall of the valve ring or the ball bag moves towards the top of the ball cage and away from the valve ring. The interventional aortic valve stent
system with the inflating type ball bag has the advantages that the ball bag replaces a traditional
valve leaflet, disassembling and changing are facilitated, compared with a
biological tissue valve leaflet, the ball bag does not have the '
chronic disease' of dysfunction of the valve, the risk of secondary surgical valve change of a patient is reduced, and the
surgical safety is high.
