Abstract
A valve stent and a valve prosthesis. The valve stent is in the shape of a mesh tube, and has a compressed state and an expanded state. The valve stent includes an inflow tract structure, a transition tract structure, an outflow tract structure, and a barb structure. The transition tract structure has a fifth end portion, a sixth end portion, and a first middle section. In the expanded state, the diameters of the radial sections of the fifth end portion and the sixth end portion are greater than the diameter of the radial section of the first middle section of the transition tract structure. The outflow tract structure has a seventh end portion and an eighth end portion. The seventh end portion of the outflow tract structure is fixedly connected to the sixth end portion of the transition tract structure, and the eighth end portion is a free end. The barb structure is disposed on the transition tract structure and the outflow tract structure, and protrudes towards the outside of the transition tract structure and/or the outflow tract structure. The valve stent and the valve prosthesis can be stably anchored on natural valves.
