  • Patent number: 12195916
    Abstract: A wire cable construct including a plurality of strands each made of a plurality of wire filaments, the strands and wire filaments arranged in a 37×7 configuration of 37 strands of 7 wire filaments each, with the strands arranged in four layers including a first, central layer of a single strand, a second layer of six strands, a third layer of twelve strands and a fourth, outermost layer of eighteen strands. The cable may have a small diameter for use in medical device applications, and the strand and wire element configuration allows the cable to carry high axial loads, minimizes bending stress when the cable is routed around a tight turn such as a small pulley, and minimizes torsion in the cable due to axial loading.

  • Publication number: 20230272578
    Abstract: Ultra-High-Strength (UHS) wires are suited to high strength wire, strands, cables and rope applications including robotics force transmission and other high-performance mono- and multifilament wire applications. The wires exhibit high strength, low stretch and fatigue durability. Exemplary UHS materials include binary molybdenum-rhenium or tungsten-rhenium alloys with between 20 and 50 wt. % rhenium. These alloys are processed from a moderate strength (<2 GPa) warm-drawn rod to drawn monofilament wire with extreme nanocrystalline grain refinement, high apparent fatigue durability, and ultimate strength levels exceeding 5 GPa in all cases, and up to 6.8 GPa at monofilament diameters ranging from 7 to 100 ?m.

  • Patent number: 11698121
    Abstract: A swaged fitting can be fixed to a wire rope while simultaneously providing a desired shape and size, thereby avoiding the need for subsequent material removal. In one application, the swaged fitting is fixed to the wire rope by a forging operation such that the fitting is securely fixed provides a straight-sided construct once fixed to the wire rope. After the forging operation and without further material removal, the straight sides of the finished fitting are generally parallel to the longitudinal axis of the wire rope, while the end surfaces of the fitting are generally perpendicular to this longitudinal axis. This arrangement provides a strong and effective force-transfer interface for, e.g., end-effectors in medical devices.
