The purpose of this study is to evaluate the safety and performance of a new version of a
coronary artery stent for treating blockages in the arteries supplying blood to the heart
muscle. The Amaranth Medical MAGNITUDE scaffold releases a drug (sirolimus) to reduce the
likelihood of the treated blood vessel developing a new blockage. In addition, the scaffold
dissolves away over time, leaving no permanent implant after the blood vessel has healed.
