Medical devices for implantation in a body vessel are provided. A medical device can include a support member enclosing an antimicrobial coating defi ning a drainage lumen extending through the support member. The antimicrobia l coating preferably includes a metal alloy comprising beryllium, nickel, co pper, cobalt and/or silicon. The metal alloy is desirably embedded in a poro us biostable material, such as an ethylvinylacetate copolymer, configured to retain oxides of the antimicrobial material while being sufficiently porous to permit fluid in the drainage lumen to penetrate the antimicrobial coatin g. The medical device may be configured, for example, as a biliary or pancre atic stent. |
