MEDICAL DEVICES WITH SELECTIVE COATING

摘要

Medical devices, such as endoprostheses, and methods of making the devices are described. In some embodiments, a medical device includes a body of interconnected bands and connectors forming an elongated tubular structure having an inner luminal wall surface and an outer abluminal wall surface and defining a central lumen or passageway. The inner luminal wall surface and side wall surface of the bands and connectors forming transverse passageways through the elongated tubular structure can bear a coating of hydrophilic material and the outer abluminal wall surface of the tubular structure can bear a coating of hydrophobic material.
