IMPROVED MEDICAL DEVICE WITH HYDROPHILIC COATING |
摘要 |
<p>A medical device is disclosed, comprising a substrate and a hydrophilic surface coating arranged on said substrate. The substrate has, on its surface coated with said hydrophilic surface coating, a surface texture with an arithmetical mean deviation of the surface profile (Ra) of at least 3 µm and/or a profile section height difference (Rdc (1-99%)) of at least 18 µm. It has surprisingly been found that the increased surface roughness of the substrate provides significant improvements in e. water retention for the hydrophilic coating.</p> |
