## 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.

## Claims

### Claim 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.

### Claim 2 (depends on 1)

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.

### Claim 3 (depends on 1)

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.

### Claim 4 (depends on 2)

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.

### Claim 5 (depends on 3)

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.

### Claim 6 (depends on 4)

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.
