Medical pt alloy and medical member formed from medical pt alloy
The present invention relates to a medical Pt alloy comprising a Pt alloy containing a metal M. In the Pt alloy according to the present invention, the metal M contains at least one of 6-11 at% of Ti, 3.5-9 at% of Zr, 5-11 at% of Nb, 6-16 at% of Mo, 4-9 at% of Hf, and 5-10 at% of Ta. The Pt alloy comprises the metal M with a total content of 3.5-18 at%, with the balance being Pt and inevitable impurities. The medical Pt alloy of the present invention has biocompatibility and X-ray visibility and also has good mechanical properties and workability. The medical Pt alloy of the present invention is formed into a medical member in the form of a Pt alloy wire rod or another form and then applied to medical devices such as embolization coils, guide wires, stents, and catheters.
