Embodiment Construction
[0438] A method for treating an intracranial aneurysm according to at least some embodiments of the present technology includes positioning an expandable occlusive member within the aneurysm and introducing an embolic element between the occlusive member and the aneurysm wall. Introduction of the embolic element both fills the space within the lumen of the aneurysm and deforms the occlusive member from the first expanded state to the second expanded state to reinforce the occlusive member at the neck of the aneurysm. Deformation of the occlusive member from the first expanded state to the second expanded state provides the additional advantage of providing the physician with visual confirmation that the delivery volume of the embolic element is sufficient to fill the aneurysm lumen. In addition to providing structural support and anchoring for the embolic element, the occlusive member also provides a scaffold for tissue remodeling and diverts blood flow from the aneurysm. In a...

Abstract
Systems and methods for treating an aneurysm in accordance with embodiments of the present technology include intravascular delivery of an occlusion member to an aneurysm lumen through an elongate shaft and intraluminal transformation of the shape of the occlusion member. The method may include introducing an embolic element into a space between an occlusion member and an inner surface of an aneurysm wall. In some embodiments, the elongate shaft is removably coupled to the distal portion of the occlusion member.
