摘要:
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.

A braided EMI protective sleeve and method of construction thereof is provided. The sleeve has a braided, tubular wall extending lengthwise along a central longitudinal axis between open opposite ends. The wall includes a plurality of filament bundles, with each filament bundle including a plurality of filaments twisted with one another to form a plurality of loops, wherein a plurality of the loops of each filament bundle are interlinked with a plurality of the loops of an adjacent filament bundle. At least some of the filament bundles include a conductive wire filament to provide the sleeve with an EMI protective shielding capacity.

An elastic fabric made by a plurality of rubber threads, first elastic wefts, second elastic wefts, first wraps, high-tensile nylons and second wraps. The rubber thread, the first elastic weft, the second elastic weft are elastic, and the first elastic weft, and the second elastic weft are knitted across and interlaced with the rubber thread at right angles such that the elastic fabric is configured to be stretched in all directions. The first elastic weft and the second elastic weft are wrapped on at least three rubber threads to form a plurality of breathing holes therebetween, and the first wrap and the second wrap are wrapped along the single rubber thread such that the elastic fabric is configured to have the solid structure and the great ventilation effect simultaneously.

A mining mesh comprises successive undulated transverse links (1,2,3,4), which are interconnected together at the bent portions of the links, whereby each pair of successive undulated links (1,2), (3,4), . . . forms a row of adjacent rectangular or square meshes (5) having four sides. The mesh is characterised in that at least at one border of the mesh, for each pair of successive links, the last side of the first link (1) is bent upwardly and backwardly over a sharp angle, whereby the end of this last side is hooked around the penultimate (last but one) side of the second link (2) and that the last side of the second link (2) is bent downwardly and backwardly over a sharp angle, whereby the end of this last side is hooked around the penultimate (last but one) side of the first link (1). The advantage is a stronger mining mesh where the overlap between two adjacent rolls can be limited.

A medical device for insertion into a hollow organ, the device having a hollow body that has a braid of wire elements having a series of terminal meshes which delimit an axial braid end, wherein the terminal meshes have outer wire elements forming a terminating edge of the braid and transition into inner wire elements arranged within the braid. The device is characterised in that a first section of the terminating edge and a second section of the terminating edge each have several outer wire elements which form together a peripheral edge of the terminating edge, which is adjusted such that the axial braid end of the hollow body can be refracted into a supply system. A method for producing such a device is also disclosed.

摘要:
Mesh cells (30) for machine-made netting (51) use pairs of mesh bars (35) made from a continuous length of material and meet at a common coupler (34). Such mesh bars (35) have a lay with a common direction throughout the length of material. In a zig-zag pattern used in knitting machine-made netting (31), the longitudinal axis of symmetry (38) of mesh bars (35) turns at each coupler (34). Towing such mesh bars (35) causes water to flow past pairs thereof in two different directions with respect to their common lay. The directions of water flow are neither parallel nor perpendicular to the longitudinal axis of symmetry (38) of the mesh bars (35). As water flows past the mesh bars (35), the cross-sectional shapes of the mesh bars (35) produce a net component of force that is oriented in a direction perpendicular to a combined drag component of force for the mesh bars (35).
