[0057] The artificial valve replacement device of the present invention is composed of a stent and a trileaflet valve fixed in the stent, see figure 2 , the stent is a net-shaped cylindrical structure composed of an aortic stent 4, a valve stent 5 and an inflow channel stent 6 connected in sequence, and this structural feature is the same as the prior art.
[0058] The top edge of the aortic stent 4 is provided with fixed ears, which are used to cooperate with the delivery device when implanted into the human body. see figure 2 , there are three fixed ears on the top edge of the aortic stent 4, only the fixed ears 60a and 60b are seen in the figure due to the angle problem. The fixed ear is a "T"-shaped structure, and the heights of the top edges of the three fixed ears are inconsistent.
[0059] The stent of the artificial valve replacement device is in a folded state when not in use, and is a dense tubular structure, which is made by laser cutting the tube of memory meta...
