Medical device, for maintaining clean surfaces, has structural element with surfaces having projections whereby average height and average spacing of projections lie between five nanometer and five hundred micrometer

摘要

Medical device has a structural component with an upper surface (O1). The upper surface has projections (E) whose average height (hM) and average spacing (d) lie between five nanometer to five hundred micrometer. The projections have an average height and average spacing of twenty nanometer to hundred micrometers.
