    摘要: An intravascular device for treating a cerebral aneurysm, the device comprising an externally controllable expandable member, the expandable member comprising a plurality of wires that define walls of the expandable member; wherein in a relaxed state of the expandable member the walls comprise at least a first wall portion in which openings defined between the wires are small enough to prevent coils positioned within the aneurysm from exiting the aneurysm, the first wall portion comprising an axial length at least as long as a neck of the aneurysm; and at least a second wall portion in which openings defined between the wires are large enough to allow blood flow through; the second wall portion axially aligned relative to the first wall portion. In some embodiments, openings of the first wall portion are small enough to reduce radial blood flow to and/or from the aneurysm.

    摘要: Coating methods and related devices are provided. Such devices can include stents. For example, the device can comprise 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 also comprise an anti-thrombogenic coating distributed over at least a portion of the device such that the pores are substantially free of webs formed by the coating.
