Publication number: 20220387042Abstract: The present technology is directed generally to devices, systems, and methods for enclosing anatomical openings. In one example, an aneurysm device is endovascularly deliverable to a site proximate to an arterial aneurysm. The aneurysm device can include 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 closure structure can include a plurality of struts forming support arms and anchoring arms. 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. A barrier can span at least a portion of the distal-facing aspect of the closure structure and be configured to further occlude a neck of the aneurysm.

Publication number: 20220280164Abstract: The present technology relates to aneurysm devices with additional anchoring mechanisms, and associated systems and methods. The aneurysm device is endovascularly deliverable to a site proximate an aneurysm near a parent artery with bifurcating branches. The device can include a closure structure comprising a distal-facing aspect configured to at least partially occlude the aneurysm. The closure structure can be formed from a generally flat pattern and is transformable between a compressed configuration and a deployed configuration. The device can also have one or more lodging elements which fold to form loop elements configured for anchoring within at least one of the bifurcating branches. The struts of the lodging elements can include hinge points which bias the folding of the lodging elements. The devices further include a supplemental stabilizer connected to the closure structure and configured to reside in the parent artery.Type: ApplicationFiled: May 27, 2022Publication date: September 8, 2022Applicant: PULSAR VASCULAR, INC.Inventor: Brent GERBERDING
