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.
