Niti-type medical guide wire and method of producing the same |
摘要 |
A medical guidewire comprised of an NiTi-based alloy having a high elasticity over a wide range of strain, excellent straightness, and preferable shape and characteristics of a stress-strain curve in a tensile test. The wire is obtained by applying a predetermined tension to a cold drawn NiTi-based alloy wire and mechanical straightening it under conditions of a predetermined torsional shear strain and temperature and shows superior pushability, torque transmission, and reinsertability as a medical guidewire, so is preferable for a catheter guidewire, endoscope guidewire, etc.
