Abstract
The invention relates to biodegradable, metal alloys, methods for their preparation and applications for their use. The alloys include magnesium and other components, such as, yttrium, calcium, zirconium, and zinc. These elements are alloyed together in specific combinations and amounts in order to achieve an alloy having desired properties and characteristics. In certain embodiments, strontium or cerium may be included as an additive. The resulting alloys are particularly suitable for forming various medical devices for implantation into the body of a patient.
