摘要:
The invention relates to a medical device for introduction into a hollow organ, comprising a compressible and expandable lattice structure (10) that comprises a plurality of first wires (11) and a plurality of second wires (12), each said plurality of wires being wound in the shape of a spiral around a common longitudinal axis and having different spiral directions such that the first wires (11) and the second wires (12) intersect to form meshes (15). The lattice structure (10) has a profiled circumferential terminating edge (20) that has multiple profile sections (25), each of which has smooth section edges (21, 22) that extend in different spiral directions along the profile section (25) and converge to form a tip (26) of the profile section (25). The invention is characterized in that each of the section edges (21, 22) is formed by at least two wires (11), at least one respective wire (11, 12) of which is deflected at a deflecting point (23) of the respective section edge (21, 22) at the transition of the lattice structure (10) into the terminating edge (20) such that the deflected wire (11, 12) extends along the section edge (21, 22) in a different spiral direction than within the lattice structure (10). The deflected wire (11, 12) is an individual wire that is only deflected at the respective section edge (21, 22) of the terminating edge (20).

The invention is an upper for an article of footwear that includes a textile having fusible filaments or fibers. The textile is incorporated into the upper and specific areas of the upper are heated such that the fusible filaments or fibers fuse with other filaments or fibers to form fused areas. In comparison with unfused areas of the upper, the fused areas may impart properties that include greater stretch-resistance, stability, support, abrasion-resistance, durability, and stiffness, for example. In addition, the fused areas generally provide air-permeability without significantly increasing the weight of the footwear.

The invention relates to a medical device having an expandable braided mesh (10) consisting of wires (11, 12) which cross over one another and which form loops (13, 14) on at least one long end (15) of the braided mesh (10). The invention is characterised in that a first wire (11) forms a first loop (13) and a second wire (12) forms a second loop (14), wherein the first loop (13) and the second loop (14) are congruent with one another at least in sections in an expanded state of the braided mesh (10) and are disposed spaced apart from one another in a compressed state of the braided mesh (10).

The invention relates to a medical device for insertion into a hollow organ, comprising a hollow body (10) that has a braid (11) of wire elements (12) having a series (13) of terminal meshes (14a, 14b, 14c, 14d) which delimit an axial braid end, wherein the terminal meshes (14a, 14b, 14c, 14d) have outer wire elements (12a, 12b, 12c, 12d) forming a terminating edge (16) of the braid (11) and transition into inner wire elements (12a', 12b', 12c', 12d') arranged within the braid (11). The invention is characterised in that a first section (16a) of the terminating edge (16) and a second section (16b) of the terminating edge (16) each have several outer wire elements (12a, 12b, 12c, 12d) which form together a peripheral edge (15a) of the terminating edge (16), which is adjusted such that the axial braid end (15) of the hollow body (10) can be retracted into a supply system. The invention further relates to a method for producing such a device.

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.

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).
