Woven textile
A woven textile is provided, including at least two blocks connected with each other. Each of the two blocks has an upper layer and a lower layer which are woven and fixed by a binding thread, and the upper layer and the lower layer are respectively composed of woven braids which extend meanderingly. The textile braid of the upper layer and the textile braid of the lower layer define a plurality of meshes, and the textile braids of the two blocks have different diameters so that the meshes on the two blocks have different dimensions.
Braided textile sleeve with integrated opening and self-sustaining expanded and contracted states and method of construction thereof
A protective textile having at least one integrated opening and method of construction thereof is provided. The sleeve includes a braided, tubular wall extending lengthwise in relation to a central longitudinal axis between opposite ends. The wall has a first state with a decreased length, increased cross-sectional area and a second state with an increased length, decreased cross-sectional area, as viewed in cross-section taken generally transversely to the central longitudinal axis. The wall further includes braided, heat-set yarns imparting a bias on the wall, wherein the bias causes the wall to remain substantially in the first and second states absent some externally applied force. The wall also includes at least one opening having a circumferentially continuous periphery bounding the opening, wherein the periphery is formed, at least in part, by braided yarns reversing direction from one S or Z helical direction to the opposite S or Z helical direction.

Each of the two blocks has an upper layer and a lower layer which are woven and fixed by a binding thread, and the upper layer and the lower layer are respectively composed of woven braids which extend meanderingly. The textile braid of the upper layer and the textile braid of the lower layer define a plurality of meshes, and the textile braids of the two blocks have different heights so that the meshes on the two blocks have different dimensions.
WOVEN TEXTILE
The woven textile includes an upper layer, a lower layer, a binding thread, and a third braid. The upper layer and the lower layer include at least one first braid and at least one second braid respectively. The first and the second braids extend in a meandering way to form a plurality of hollow portions. The upper layer and the lower layer overlap to have plural overlapping portions aligned along the horizontal direction. Plural rows of said overlapping portions are arranged along the longitudinal direction. The binding thread fixes the overlapping portions in a same row together by weaving so that the upper layer and the lower layer are positioned. The third braid fixes the overlapping portions of a same row with the overlapping portions of an other same row by weaving so that a distance between said two rows of overlapping portions is restricted.

PERSONALIZED AORTIC VALVE PROSTHESIS
A personalized prosthetic valve for implantation at a native valve treatment site includes a self-expanding mesh and a plurality of valve leaflets coupled to the mesh. The mesh may be delivered to the native valve in a collapsed configuration, and in an expanded configuration the mesh engages the native valve. The mesh in the expanded configuration is also personalized to match the treatment site, such that the outer mesh surface substantially matches the treatment site shape and size. The self-expanding mesh forms a central lumen configured to allow blood or other body fluids to pass therethrough. In the open configuration, blood passes through the prosthetic valve, and in the closed configuration, the plurality of leaflets are closer together and blood is prevented from flowing upstream through the prosthetic valve.

BRAIDED TEXTILE SLEEVE WITH AXIALLY COLLAPSIBLE, ANTI-KINKING FEATURE AND METHOD OF CONSTRUCTION THEREOF
A protective textile sleeve and method of construction thereof are provided. The sleeve has a tubular wall of braided yarns extending lengthwise along a central longitudinal axis between opposite ends. At least some of the braided yarns including heat-set yarns, and the wall has a plurality of annular first regions forming generally convex ridges and a plurality of annular second regions forming generally concave valleys. The first regions alternate with the second regions along the central longitudinal axis. The first regions include a plurality of twisted yarns forming a plurality of closed loops, wherein at least some of the braided yarns pass through at least some of the closed loops within the first regions to enhance the radial stiffness and resistance of the wall to kinking,
