摘要： An electrically conductive cable (100) includes a number of conductive strands (102, 104, 106) which are twined to form a wire rope (108) without a central core. The wire rope (108) is drawn through a die (110) to reduce its diameter until the outer surface of the cable (100) is smooth and the cross section of the cable (100) is substantially circular. According to a presently preferred embodiment, the electrically conductive cable (100) is successively drawn through four dies (110) of decreasing diameter so that the overall diameter of the wire rope (108) is reduced by 30-40 %. The resulting electrically conductive cable (100) has the tensile strength advantage and the low resistance advantage of a solid conductor with the flexibility advantage of a wire rope cable. In addition, the smooth outer surface of the electrically conductive cable (100) according to the invention is easily insulated with an extruded material.

摘要： Medical devices are provided which utilize a highly flexible cable of two and preferably three or more strands of wire, at least one of which is a nickel-titanium alloy strand. The strands are twined to form a wire rope which is drawn through successive dies to reduce its diameter until the outer surface of the cable is substantially smooth. A cable of all nickel-titanium alloy strands has been found to have an improved elasticity over a superelastic nickel-titanium wire of the same diameter. The cable is used in medical devices in which increased elasticity of a wire-like element is desired. Twisted and drawn cables incorporating a strand of a radiopaque metal or alloy with one or more nickel-titanium strands may be used in devices in which radiopacity of a flexible portion of the device is desired. Twisted and drawn cables incorporating a strand of a highly electrically conductive metal or alloy with one or more nickel-titanium strands may be used in devices in which electrical conductivity of a flexible portion of the device is desired.

摘要： A highly flexible cable (100) includes two, preferably three or more strands or nickel-titanium alloy wires (102, 104, 106) which are twined to form a wire rope (108). The nickel-titanium alloy wire rope (108) is drawn through successive dies (110) to reduce its diameter until the outer surface of the cable (100) is substantially smooth, the overall cross section of the cable (100) is circular, and the overall diameter of the wire rope (108) is reduced by 20-50 %. The cable (100) is then annealed to remove the effects of cold working. The resulting cable has been found to have an improved flexibility (i.e., a lower modulus of elasticity) relative to single strand nickel-titanium wires (102, 104, 106) of the same diameter.

摘要： Electrical cable (10) of the present invention include cables made from plated filaments (12, 14, 16) which are first twisted together and then drawn through reducing dies (or swaged), filaments which are twisted together around a core material which melts or deforms during drawing of the cable through reducing dies, filaments which are twisted around a tube prior to drawing through reducing methods. The cables (10) exhibit a conductivity comparable to cables having greater diameter and weight. The smaller diameter of the cables of the invention allows them to be used as leads for electronic components in order to achieve reduced parasitic capacitance without increased resistivity or reactance or component package size. The cold working of the cables of the invention provides them with enhanced flexibility and fatigue strength. The combination of materials used in the cables of the invention provides them with enhanced flexibility and fatigue strength. The combination of materials used in the cable of the invention provides them with resistance to corrosion and the adverse effects of aging as well as enhanced conductivity. Cables formed according to the invention with a hollow tube core can be self-cooling, or easily cooled by flowing a coolant through the hollow core. The hollow tube core also enhances fatigue strength, resists the effects of aging, and lowers the weight of the cable. Cables formed with a silver core are also self-cooling.
