Abstract
Antimicrobial catheters and medical devices are provided. In some aspects, a low durometer aliphatic polyether polyurethane may be impregnated with a first antimicrobial agent (e.g., minocycline and rifampin) and coated with a second antimicrobial agent (e.g., chlorhexidine, gendine, or gardine). The antimicrobial catheters may display improved flexibility and resistance to kinking. Methods of producing the antimicrobial catheters are also provided.
