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. 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.
Claims
exact text as granted — not AI-modified1 . An implantable medical device comprising a biodegradable alloy, wherein the alloy is substantially austenite in structure, and wherein the alloy has an average grain size in the range of about 0.5 microns to about 20 microns or a surface to volume ratio for individual grains of, on average, greater than 0.1μ −1 .
