Abstract

Described herein are vascular remodeling devices that 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 anchors 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.
