Abstract: Treatment of aneurysms can be improved by delivering an occlusive member (e.g., an expandable braid) to an aneurysm sac in conjunction with an embolic element (e.g., coils, embolic material). A treatment system for such treatment can include an electrolytically corrodible conduit having a proximal portion, a distal portion, and a detachment zone between the proximal portion and the distal portion. An occlusive member having a proximal hub is coupled to the conduit distal portion. The conduit has a lumen configured to pass an embolic element therethrough. An inner electrode assembly can be slidably disposed within the conduit lumen to facilitate electrolytic detachment of the occlusive member at the detachment zone.

Abstract: Devices for treating vascular defects and associated systems and methods are disclosed herein. In some embodiments, an occlusive device for treating an aneurysm includes an expandable mesh configured to span a neck of the aneurysm. The expandable mesh can include an upper wall and a lower wall. The occlusive device can also include an insert positioned within the expandable mesh between the upper and lower walls. The insert can have an inner surface and an outer surface. The inner surface of the insert can face the upper wall of the expandable mesh, and the outer surface of the insert can face the lower wall of the expandable mesh. The insert can be configured to promote thrombosis when the occlusive device is deployed within the aneurysm.

Abstract: Devices for treating vascular defects and associated systems and methods are disclosed herein. In some embodiments, for example, an occlusive device for treating an aneurysm includes a first mesh formed from a first tubular braid, the first mesh including a first petal-shaped region formed from a first flattened section of the first tubular braid. The first mesh can be coupled to a second mesh formed from a second tubular braid. The second mesh can include a second petal-shaped region formed from a second flattened section of the second tubular braid. When the occlusive device is deployed within the aneurysm, the first and second petal-shaped regions can extend at least partially over a neck of the aneurysm.
