  • Patent number: 6117480
    Abstract: Medical cannulas are typically provided with a silicone coating to improve incision performance. In order to produce a thin, continuous and even coating layer, silicone oil is provided at one side of an elastic foil and the foil is penetrated by the uncoated cannula from an opposite side. During this operation the cannula is wetted by the silicone oil. During withdrawal of the cannula from the foil, excess silicone oil is removed from the cannula and an even, particle-free thin coating which has no bulge- or bead-forming tendency during incision is obtained. Subsequently, the silicone coating is dried.
