The implant of wherein the first foil has a first surface claim 1 , and the anti-microbial agent is present as a coating on the first surface of the foil. This application is a continuation of and claims priority from co-pending U.S. Ser. No. 12/336,055, entitled “Anti-Infective Spinal Rod with Surface Features” (Fisher), filed Dec. 16, 2008 (DEP6204USNP), the specification of which is incorporated by reference in its entirety.Infection rates in spine surgery at typically below 3% whereas the rates in instrumented spine surgery range from 1-17%. The increased rate of infection is thought to be attributable to the use of synthetic biomaterials, longer procedure times, and more severe disease conditions that merit the placement of orthopedic implants.It is strongly suspected that the presence of a synthetic biomaterial in a wound will increase the infection rate by two means—foreign body response and biofilm formation. Foreign body response is the body's reaction to any implanted material and typically creates a local hyper-immune response to the presence of a foreign material. Biofilm formation occurs when bacteria colonize a biomaterial surface and create a mucous layer to protect the colony from the host immune system. Once a bacterial biofilm has formed, it is unlikely that the immune system can resolve the infection.One way to prevent device colonization is to apply a coating that prevents biofilm formation or has native antimicrobial properties. Unfortunately, applying coatings to spinal and orthopedic ...
