Abstract
An implantable medical device is provided that degrades upon contact with body fluids so as to limit its residence time within the body. The device is formed of a porous corrodible metal to simultaneously provide high strength and an accelerated corrosion rate. The corrosion rate of a device formed of metal subject to self-dissolution or of a combination of metals subject to galvanic corrosion is accelerated by its porous structure. Coating the corrodible metallic device with a degradable polymer serves to delay the onset of corrosion of the underlying metallic structure.
