Patent ID: 8808724

Claim:
A medical device, comprising: a non-absorbable structure having a surface; and a coating consisting of a first long lasting, short-ranging antimicrobial coating and a second fast acting, long-ranging discontinuous polymeric antimicrobial coating wherein the first long lasting, short-ranging antimicrobial coating is on at least part of the surface, said first antimicrobial coating having a coating surface and comprising a first long-lasting and short-ranging antimicrobial agent; and, the second fast acting, long-ranging discontinuous polymeric antimicrobial coating comprising a second antimicrobial agent, wherein said second antimicrobial coating is applied over at least part of the coating surface of the first antimicrobial coating such that it has a microstructure, and wherein the microstructure of the second discontinuous coating comprises discrete sections, each section having a substantially geometric shape, wherein the second coating comprises a bioabsorbable polymer, and wherein the microstructure of the second coating is substantially equivalent to the length of a bacteria.
