Abstract:
1. A medical device that is at least partially formed of a metal alloy which improves the strength and ductility of the medical device, said metal alloy including at least about 95 weight percent of a solid solution, said metal alloy including 45-50 weight percent rhenium and 50-55 weight percent molybdenum, said metal alloy including carbon and oxygen and having a carbon to oxygen atomic ratio of at least about 2:1, said metal alloy having a nitrogen content of less than about 20 ppm, a carbon content of less than about 150 ppm, and an oxygen content of less than about 50 ppm, said metal alloy having an average yield strength of at least about 98 ksi and an average ultimate tensile strength of at least about 100 ksi, said metal alloy having an average grain size of over 5 ASTM, said metal alloy having an average tensile elongation of at least about 25% said metal alloy having a carbon to nitrogen atomic ratio of less than about 40:1 and an oxygen to nitrogen atomic ratio of less than about 30:1, at least one region of said medical device includes at least one biological agent.
