VALVE STENT AND PRESTHETIC VALVE HAVING THE SAME

The present application provides a valve stent and a prosthetic valve having the same, and belongs to the technical field of cardiac valves. The valve stent comprises a stent body, a positioning ring and elastic connection wires, wherein the positioning ring in a compressed state is adapted to be arranged in series with the stent body sequentially along an axis thereof, and when the positioning ring has elastically deformed from the compressed state to a propped open state, the positioning ring becomes coaxially sleeved on the stent body due to traction of the elastic connection wire. In the valve stent of the present application, after being implanted, the positioning ring can automatically expand to reach the propped open state by elastic deformation, and due to the traction of the elastic connection wire, the positioning ring can become coaxially sleeved on the stent body.
