Wire rope

Abstract

A wire rope for use in a medical procedure includes a multi-strand coil formed by twisting multiple metal wires together. In the wire rope, gaps are located between the multiple metal wires along an axis of the multi-strand coil. The gaps between the multiple metal wires include a first gap and a second gap that differ in width.

What is claimed is: 
     
         1 . A wire rope for use in a medical procedure, the wire rope comprising:
 a first multi-strand coil including a plurality of metal wires, wherein
 the first multi-strand coil has gaps between the plurality of metal wires along an axis of the first multi-strand coil. 
   
     
     
         2 . The wire rope according to  claim 1 , wherein the gaps between the plurality of metal wires include a first gap and a second gap that differ in width. 
     
     
         3 . The wire rope according to  claim 1 , further comprising:
 a second multi-strand coil,   wherein the second multi-strand coil is disposed inside the first multi-strand coil such that the first multi-strand coil on an outer side is wound around an outer circumference of the second multi-strand coil on an inner side, and   wherein the first multi-strand coil on the outer side is wound in the same direction as the second multi-strand coil on the inner side, and an angle at which the first multi-strand coil on the outer side is wound when viewed in vertical section differs from an angle at which the second multi-strand coil on the inner side is wound when viewed in vertical section.   
     
     
         4 . The wire rope according to  claim 2 , further comprising:
 a second multi-strand coil,   wherein the second multi-strand coil is disposed inside the first multi-strand coil such that the first multi-strand coil on an outer side is wound around an outer circumference of the second multi-strand coil on an inner side, and   wherein the first multi-strand coil on the outer side is wound in the same direction as the second multi-strand coil on the inner side, and an angle at which the first multi-strand coil on the outer side is wound when viewed in vertical section differs from an angle at which the second multi-strand coil on the inner side is wound when viewed in vertical section.   
     
     
         5 . The wire rope according to  claim 3 , wherein the angle at which the first multi-strand coil on the outer side is wound when viewed in vertical section is larger than the angle at which the second multi-strand coil on the inner side is wound when viewed in vertical section. 
     
     
         6 . The wire rope according to  claim 4 , wherein the angle at which the first multi-strand coil on the outer side is wound when viewed in vertical section is larger than the angle at which the second multi-strand coil on the inner side is wound when viewed in vertical section.
