Abstract
A prosthetic heart valve is disclosed that is deformable between collapsed, radially uncompressed, and target conditions. The prosthetic heart valve includes an inner frame, at least one leaflet, and a braided wire mesh arranged outside and coupled to the inner frame by a coupling portion. The braided wire mesh includes a body portion between the coupling portion and a flared portion. In the radially uncompressed condition, the prosthetic heart valve forms a cavity surrounded by the braided wire mesh and the inner frame. In the target condition, only a part of the length of the body portion is radially compressed along an axis extending from an upstream side to a downstream side. In the collapsed condition, the inner frame and braided wire mesh are radially collapsed over their entire length. In the radially uncompressed condition, the body portion is tubular and the braided wire mesh has a rotationally symmetric circumference.
