1. An aneurysm device endovascularly deliverable to a site proximate to an aneurysm in an artery, the aneurysm device comprising:
- a closure structure comprising a distal-facing aspect configured to at least partially span the aneurysm, and a proximal-facing aspect configured to arch over lumina of the artery,wherein the closure structure comprises a perimeter support including a plurality of struts and an inner support including a plurality of struts, andwherein the inner support is within a boundary defined by the perimeter support;
a first coil tip extending from the closure structure and configured to be at least partially contained within the aneurysm; and
a second coil tip extending from the closure structure and configured to be at least partially contained within the aneurysm,wherein the first and second coil tips extend peripherally from opposing lateral sides of the closure structure,wherein a material of the first and the second coil tips is softer than a material of the closure structure, perimeter support, and inner support.

Abstract
The present disclosure describes implantable therapeutic devices and methods for endovascular placement of devices at a target site, such as an opening at a neck of an aneurysm. In particular, selected embodiments of the present technology comprise a coil loop, or tip, on a portion of the implantable device. The coil tip can provide a soft and/or smooth interface with the aneurysm and can provide improved coverage of the neck of the aneurysm.

11. An aneurysm device endovascularly deliverable to a site proximate to an aneurysm, the aneurysm device comprising:
-
a closure structure having a distal-facing aspect configured to at least partially occlude the aneurysm; wherein the closure structure comprises a perimeter support and an inner support, and wherein the inner support is within a boundary defined by the perimeter support; a plurality of coil tips extending peripherally from the closure structure and configured to be at least partially contained in the aneurysm, wherein the coil tips have a softer composition than that of the closure structure; and a supplemental stabilizer connected to the closure structure, wherein the supplemental stabilizer is configured to reside in the artery and press outward against a luminal wall thereof. - View Dependent Claims (12, 13, 14)
