<p>There is disclosed a medical device, such as a urinary catheter, comprising a substrate material, a hydrophilic surface coating, e.g. comprising polyvinylpyrrolidone (PVP), arranged on at least a part of the surface of said substrate material, and an antibacterial layer comprising oligodynamic metal arranged between the substrate material and the hydrophilic surface coating. Further, the hydrophilic surface coating has a thickness large enough to provide a controlled release of oligodynamic metal ions through the hydrophilic surface coating, such as a thickness when dry that exceeds 3 µm. Hereby, the variation in the release of the oligodynamic metal ions is significantly reduced, enabling an improved control of the release. A corresponding method is also disclosed.</p> |
