摘要：
Methods for forming an expandable tubular body having a plurality of braided filaments including a first filament including platinum or platinum alloy and a second filament including cobalt-chromium alloy. The methods include applying a first phosphorylcholine material directly on the platinum or platinum alloy of the first filament and applying a silane material on the second filament followed by a second phosphorylcholine material on the silane material on the second filament. The first and second phosphorylcholine materials each define a thickness of less than 100 nanometers.
