Devices, systems and methods for enclosing an anatomical opening

摘要

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.

主权项

1. An aneurysm device endovascularly deliverable to a site proximate to an aneurysm, the aneurysm device comprising:
an arched closure structure comprising 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, wherein the arch is configured to span unobtrusively over the lumina and forms no incursion into the vascular flow path; a supplemental stabilizer connected to the closure structure, the supplemental stabilizer configured to reside in the artery and press outward against a luminal wall thereof; and a barrier spanning at least a portion of the distal-facing aspect of the closure structure, the barrier having an aperture therein configured to provide access to the aneurysm, wherein the aperture is sized and shaped to allow passage of a catheter therethrough.
