摘要：
The present disclosure is directed to a drug-eluting implantable medical devices that includes a tantalum-alloy body having a drug-eluting coating thereon for delivering a drug to treat, for example, restenosis. In an embodiment, an implantable medical device includes a body sized and configured to be implanted in a living subject. At least a portion of the body may comprise a tantalum alloy. The tantalum alloy includes a tantalum content of about 77 weight % (“wt %”) to about 92 wt %, a niobium content of about 7 wt % to about 13 wt %, and a tungsten content of about 1 wt % to about 10 wt %. The tantalum alloy exhibits at least one mechanical property modified by heat treatment thereof. The body has a drug-eluting coating thereon.
