Abstract

A bioabsorbable material composition includes magnesium (Mg), lithium (Li) and calcium (Ca). Lithium is provided in a sufficient amount to enhance material ductility, while also being provided in a sufficiently low amount to maintain corrosion resistance at suitable levels. Calcium is provided in a sufficient amount to enhance mechanical strength and/or further influence the rate of corrosion, while also being provided in a sufficiently low amount to preserve material ductility. The resultant ductile base material may be cold-worked to enhance strength, such as for medical applications. In one application, the material may be drawn into a fine wire, which may be used to create resorbable structures for use in vivo such as stents.
