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.

Occlusive devices with thrombogenic inserts

Devices, systems, and methods for treating aneurysms are disclosed herein. According to some embodiments, the present technology includes a treatment system comprising a delivery shaft, a manipulation shaft slidably positioned within the lumen of the delivery shaft, and an occlusive device configured for implantation within the aneurysm. The occlusive device can comprise a plurality of filaments that are secured to one another at a proximal end of the occlusive device by a cured material. The occlusive device can comprise inner and outer layers of braided filaments, wherein the proximal end region of the inner layer has an exposed portion that extends proximally beyond the proximal end region of the outer layer, and wherein the cured material extends into and fills interstices between the braided filaments at the proximal end regions of the inner and outer layers.
