COBALT-NICKEL-CHROMIUM-MOLYBDENUM QUARTERNARY ALLOY HAVING DURABILITY TO FATIGUE OF MEDICAL DEVICE IN VESSEL LUMEN

摘要

PROBLEM TO BE SOLVED: To provide a precursor and the related method for manufacturing a stent in a vessel and an implantable medical device to give a chance to a designer for developing an equipment according to practical uses.

SOLUTION: A biocompatible solid solution alloy is formed as various implantable medical devices. The solid solution alloy includes a combination of elements with a specific ratio for keeping necessaries for implantable medical devices and improving the durability to the fatigue. The biocompatible solid solution alloy is cobalt-nickel-chromium-molybdenum quaternary alloy of which the content of titanium is practically reduced.
