Devices, systems and methods for enclosing an anatomical opening
First Claim
1. An aneurysm enclosure framework in a planar configuration prior to assembly into a deliverable configuration, the aneurysm enclosure framework comprising:
- a central framework portion and two support framework portions, the support framework portions connected to opposite sides of the central framework portion, the central and support framework portions aligned along a longitudinal axis,wherein the central framework portion comprises a set of central struts forming at least one quadrilateral form with first and second longitudinal junctions joining the struts at two longitudinal apices, and two lateral junctions joining the struts at apices of a lateral axis; and
a radiopaque composition incorporated in a laterally asymmetric pattern on the central framework portion.

Abstract
The present technology is directed generally to devices, systems, and methods for enclosing anatomical openings. In several embodiments, an aneurysm device is endovascularly deliverable to a site proximate to an arterial aneurysm. The aneurysm device includes a closure structure having a distal-facing aspect configured to at least partially occlude the aneurysm and a proximal-facing aspect configured to arch over lumina of an artery. The device further includes a supplemental stabilizer connected to the closure structure and configured to reside in the artery and press outward against a luminal wall thereof. In some embodiments, the device can also include a barrier spanning at least a portion of the distal-facing aspect of the closure structure and configured to further occlude a neck of the aneurysm. In further embodiments, the closure structure can be configured to restrict and/or divert flow to or from the aneurysm.
