Abstract
The invention provides medical devices comprising high-strength alloys which degrade over time in the body of a human or animal, at controlled degradation rates, without generating emboli and which have enhanced degradation due to the presence of a halogen component. In one embodiment the alloy is formed into a bone fixation device such as an anchor, screw, plate, support or rod. In another embodiment the alloy is formed into a tissue fastening device such as staple. In yet another embodiment, the alloy is formed into a dental implant or a stent.
Claims37
An implantable medical device comprising a biodegradable alloy, wherein the alloy is iron based and comprises an iron reactive component, wherein the alloy reacts with a bodily fluid when it is in contact with the fluid and wherein the degradation rate of the alloy when implanted in a biological subject is faster than the degradation rate of an alloy having the same composition as the said alloy except the absence of the iron reactive component.
