Abstract
A new type of medical guidewire with functionally graded characteristics from the tip to the end was developed using Cu-Al-Mn-based alloys. The superelasticity (SE) of the Cu-Al-Mn-based alloys can be drastically improved by controlling the grain size, and the present alloys were hardened by ageing at around 300oC. Based on these results, a Cu-Al-Mn-based core wire for a guidewire with a superelastic tip portion and a high rigid body portion was manufactured. This guidewire shows excellent pushability and torquability superior to those of stainless steel and Ti-Ni guidewires.
