    Abstract: Expandable devices for occluding bifurcation aneurysms are disclosed herein. Several of the embodiments are directed towards an expandable device comprising a mesh configured to be deployed at a treatment site including blood vessel bifurcation of a human patient so that the mesh extends across a neck of an aneurysm and prevents or limits blood flow through the mesh and into the aneurysm. The mesh can comprise one or more circumferentially discontinuous portions so that, when the device is deployed at the treatment site, the device does not substantially impede flow from a parent blood vessel to two or more branching blood vessels. Systems and methods for delivering an expandable device of the present technology are also disclosed herein.

    Abstract: Vascular remodeling devices can include a proximal section, an intermediate section, and a distal section. During deployment, the proximal section can expand from a compressed delivery state to an expanded state and anchor the device in an afferent vessel of a bifurcation. The distal section expands from the compressed delivery state to an expanded state that may be substantially planar, approximately semi-spherical, umbrella shaped, or reverse umbrella shaped. The distal section is positioned in a bifurcation junction across the neck of an aneurysm or within an aneurysm. The intermediate section allows perfusion to efferent vessels. Before or after the device is in position, embolic material may be used to treat the aneurysm. The distal section can act as a scaffolding to prevent herniation of the embolic material. The device can be used for clot retrieval with integral distal embolic protection.

    Abstract: Medical devices that include a tubular member with a plurality of braided filaments, each filament crossing another of the filaments at a respective crossing point forming 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 pores have an average pore size that is less than or equal to about 500 microns when the tubular member is in an expanded state, the filaments possessing antithrombogenic surfaces to increase antithrombogenicity of the medical device with pores substantially free of webs formed by antithrombogenic material, such that fewer than 5% of the crossing points have webs formed by antithrombogenic material thereby permitting the pores to be substantially free of webs.

    Abstract: 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.
