A surgical snare instrument includes an elongated tubular sheath having proximal and distal ends, a flexible torqueable shaft having proximal and distal ends extending through and axially movable relative to the sheath, a snare loop at the distal end of the shaft, and a handle coupled to the proximal ends of the sheath and shaft for moving the shaft relative to the sheath and for rotating the shaft relative to the sheath so that the snare loop, when extended beyond the distal end of the sheath, is rotatable relative to the distal end of the sheath. The shaft is preferably a multifilament twisted and drawn cable. The filaments of the multifilament twisted and drawn cable are preferably either stainless steel, nickel-titanium alloy, or a combination of the two. Such a shaft has been demonstrated to provide the high torqueability necessary for controlled rotation of the snare loop.

A highly flexible radiopaque cable includes two, and preferably three or more strands of nickel-titanium (NiTi) alloy wire which are twined about a higher density core wire preferably made of at least one of silver, gold, tungsten, or platinum-iridium to form a wire rope. Other high density core wires may be used. The wire rope is drawn through successive dies to reduce its diameter until the outer surface of the cable is substantially smooth, the cross section of the cable is substantially circular, and the overall diameter of the wire rope is reduced by 20-50%. The cable is then annealed to remove the effects of cold working. The resulting cable has been found to have a substantially equal or improved flexibility (i. e. , a lower modulus of elasticity) relative to single strand nickel-titanium wires of the same diameter and a higher radiopacity. In an alternative embodiment, no core wire is utilized, and the higher density wire is drawn with two or more strands of NiTi wire.

A coaxial cable includes an inner conductor, a multifilament twisted and drawn or swaged tubular cable outer conductor, and a dielectric (insulative) material therebetween. According to one embodiment, the filaments of the multifilament twisted and drawn or swaged outer conductor are twisted about a central inner conductor provided with an insulative sheath. The outer conductor filaments are arranged such that when they are drawn or swaged, the compressive forces are directed on neighboring filaments and not directed radially inward toward the inner conductor, thereby preventing deformation of the inner conductor. According to another embodiment, each of the filaments is provided with an insulative sheath. According to other embodiments, a cable is formed with a central filament harder than the surrounding filaments. The central filament is withdrawn leaving behind a twisted and drawn or swaged tube with a hollow.

A hybrid cable includes an optical fiber and a multifilament twisted and drawn or swaged electrical conductor. According to one embodiment, the filaments of the multifilament twisted and drawn or swaged electrical conductor are twisted about the optical fiber and then drawn through one or more dies or swaged. In a second embodiment, a metal tube is drawn through one or more dies, an optical fiber is provided in the tube, and then the tube is drawn again with the optical fiber contained therein to result in a drawn filled tube having a central optical fiber. The drawn filled tube is then used a central filament and a plurality of conductive filaments are twisted and about the central filament and the twisted assembly is then drawn or swaged to result in a hybrid cable. In a third embodiment, a multifilament twisted and drawn or swaged cable is formed with a central filament harder than the surrounding the filaments. The central filament is subsequently withdrawn from the surrounding filaments and a twisted and drawn or swaged tube results. An optical fiber is then fed into or pulled through the center of the twisted and drawn or swaged tube to provide a hybrid cable. According to fourth and fifth embodiments, a hybrid cable is provided which includes at least one multifilament twisted and drawn or swaged cable and at least one optical fiber which are arranged parallel within a sheath.

A garment adapted to support a female chest includes a pair of frontal cup portions of flexible material adapted to cover the chest area of a wearer, each of the cup portions having a perimeter. A multifilament twisted and drawn or swaged cable support element is attached to a portion of the perimeter to provide support for each cup in a manner which is comfortable to the wearer. The multifilament twisted and drawn or swaged cable support element is preferably comprised of a plurality of nickel-titanium wires or a plurality of stainless steel wires, which were formed by first twisting multiple filaments together and then drawing the twisted filaments through multiple dies and/or swaging to form a cable. The multifilament twisted and drawn or swaged cable provides superior support and comfort.
