Tubing material, method for producing tubing material, and stent, guidewire, and pressure guidewire

Abstract

Provided are a tubing material which can be industrially manufactured by a simple method, consisting of a Ni—Ti-based alloy material, having improved roughness of the inner wall surface, and superior in durability against rotary bending, a method for producing this, as well as a stent, a guide wire, and a pressure guide wire made using the tubing material. The tubing material consists of a Ni—Ti-based alloy, in which an arithmetic mean height Sa of an inner wall surface is 0.08 μm or more and 0.55 μm or less.

Dependencies are inferred from the claim text.
