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.

Abstract: Methods for applying layers to medical devices and related devices are provided. Such devices can include stents. For example, the device can include a sidewall and a plurality of pores in the sidewall that are sized to inhibit flow of blood through the sidewall into an aneurysm to a degree sufficient to lead to thrombosis and healing of the aneurysm when the tubular member is positioned in a blood vessel and adjacent to the aneurysm. The device can have an anti-thrombogenic outer layer distributed over at least a portion of the device.

Abstract: In some examples, a catheter includes an elongated body and an expandable member at a distal portion of the elongated body and defining at least part of a distal tip of the catheter. The expandable member is formed from materials that enable a distal tip of the catheter to be radiopaque without the addition of a separate radiopaque marker (e.g., a solid metal ring of radiopaque material separate from and connected to the elongated body) at the distal tip of the catheter.
