A method is provided for making a fiber wire having a fiber bundle core and a polymer jacket. The method includes rotating a spool of fiber bundle about a first rotational axis to progressively unwind the fiber bundle from the spool. The fiber bundle includes a plurality of continuous synthetic fiber filaments. While the spool is rotated about the first rotational axis, the spool is simultaneously rotated about a second rotational axis to thereby twist the unwound fiber bundle about its longitudinal axis. The method further includes coating the twisted fiber bundle with a molten polymer, and permitting the molten polymer to cool to define a flexible outer jacket that encapsulates the twisted fiber bundle.

A wire rope having improved durability and that can be used in a medical device to be inserted into a patient's body. The wire rope includes a core wire and side wires. The core wire is a special metal element wire that has a hardness at an outer periphery in a cross-section thereof that is higher than that at a center in the cross-section thereof. The wire rope does not include grease.

Provided is an elastomer reinforcement cord with improved rust inhibition. An elastomer reinforcement cord (10) includes metal filaments and a polymer material. The elastomer reinforcement cord (10) has a multi-strand structure which includes: at least one core strand (21) formed by twisting plural metal filaments (1a) and (1b) together; and two or more sheath strands (22) each formed by twisting plural metal filaments (11a) and (11b) together, and in which the sheath strands are twisted together around the core strand. In a region surrounded by a line connecting the centers of the metal filaments constituting the outermost sheath layer of the core strand at a cross-section in a direction orthogonal to an axial direction after vulcanization of the core strand, when a region occupied by other than the metal filaments is defined as a gap region, a filling rate, which is a ratio of the area of the polymer material with respect to the gap region, is 52% to 120%.
