1. A method comprising:
- forming an expandable tubular body comprising a plurality of braided filaments, the expandable tubular body is configured to be implanted in a blood vessel, the plurality of braided filaments comprising a first filament comprising platinum or platinum alloy and a second filament comprising cobalt-chromium alloy;
applying a first phosphorylcholine material directly on the platinum or platinum alloy of the first filament;
applying a silane material to the second filament comprising the cobalt-chromium alloy, wherein the silane material comprises a silane selected from the group consisting of 3-glycidoxypropyltrimethoxysilane, 2-(3,4-epoxycyclohexyl)ethyltriethoxysilane, 2-(3,4-epoxycyclohexyl)ethyl-trimethoxysilane, (3-glycidoxypropyl)trimethoxysilane, (3-glycidoxypropyl)triethoxysilane, 5,6-epoxyhexyltriethoxysilane, (3-glycidoxypropyl)methyldiethoxysilane, (3-glycidoxypropyl)methyldimethoxysilane, (3-glycidoxypropyl)dimethylethoxysilane, 3-isocyanatopropyltriethoxysilane, (isocyanatomethyl)methyldimethoxysilane, 3-isocyanatopropyltrimethoxysilane, tris(3-trimethoxysilylpropyl)isocyanurate, (3-triethoxysilylpropyl)-t-butylcarbamate, triethoxysilylpropylethylcarbamate, 3-thiocyanatopropyltriethoxysilane, and combinations thereof; and
applying a second phosphorylcholine material on the silane material on the second filament,wherein the first and second phosphorylcholine materials each define a thickness of less than 100 nanometers.

Abstract
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.
