Application Of Antimicrobial Agents To Medical Devices

摘要

Invasive medical devices including a substantially non-eluting antimicrobial treatment are disclosed. One or more external and/or internal surfaces of the medical device include a substantially non-eluting copper-coated surface that assists in preventing microbial colonization of the coated surface. This in turn reduces the incidence of infection to the patient originating from the medical device. In one embodiment, a catheter assembly is disclosed and comprises an elongate catheter tube that defines at least one lumen, at least one extension leg including a luer connector, and a bifurcation hub including at least one fluid passageway that provides fluid communication between the extension leg and the lumen. A substantially non-eluting copper coating is disposed on a surface of at least one of the lumen, the extension leg, the luer connector, and the fluid passageway. The coating is applied via an electroless deposition process. A water-shed coating is disposed on the copper coating.

主权项

1. An medical device, comprising:
a body defining at least a portion of a fluid path, the fluid path including a surface; a substantially non-eluting copper coating disposed on at least a portion of the surface, the coating having been applied via an electroless deposition process; and a water-shed layer disposed on the copper coating.
