摘要： 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.

摘要： A coaxial cable includes an inner conductor made of a number of conductive strands which are twined to form a wire rope which is drawn through a die to reduce its diameter until the outer surface of the cable is substantially smooth and the cross section of the cable is substantially circular, an outer conductor concentrically around the inner conductor, and a dielectric between the inner and outer conductors. The strands of the cable may be a single metal or alloy wires, or may be plated wires. The outer conductor may be a highly flexible metallized tape which is helically wrapped around the dielectric. As such, the coaxial cable has substantially greater flexibility. According to a second embodiment, a coaxial cable includes inner and outer conductors, and a dielectric therebetween. The dielectric includes an outer cross-sectional shape which is preferably different from an inner cross-sectional shape of the outer conductor. As a result of the different cross-sectional shapes, channels are formed between dielectric and the outer conductor which facilitate cooling of the cable. According to a preferred aspect of the second embodiment, a cooling fluid is circulated throughout the channels to remove heat. The cooled coaxial cable provides a signal transmission medium with reduced high frequency signal attenuation.

摘要： Electrical cables of the present invention include cables made from plated filaments 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 dies, and cables which are made from combinations of these methods. The cables 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 resistance to corrosion and the adverse affects 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.

摘要： 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. In another embodiment, the higher density wire is radioactive.

摘要： A surgical snare instrument includes a tubular sheath having proximal and distal ends, a flexible 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 assembly coupled to the proximal ends of the sheath and shaft for moving the shaft axially relative to the sheath. The handle assembly is provided with cautery capability to provide a cautery current to the snare loop. The snare loop is trained to have a proximal portion which extends along an angle or curve relative to the tubular member and a distal portion which is substantially parallel to the tubular member. As such, when the snare loop is axially moved beyond the distal end of the sheath, the distal portion of the snare loop; i.e., that portion which is adapted to engage a polyp, is oriented substantially parallel, yet non-axial, with the tubular member. According to one embodiment of the invention, the shaft is torqueable, preferably made from a multifilament twisted and drawn or swaged cable. The handle is preferably additionally adapted to axially rotate the sheath relative to the shaft and the snare loop to facilitate maneuvering the snare loop. According to another embodiment of the invention, the snare loop is provided with a net element adapted to capture a polyp severed by the snare loop.
