Abstract: A device for treating an intracranial aneurysm in accordance with an embodiment of the present technology includes an elongate conduit body defining an axial lumen through which the conduit body is configured to convey liquid embolic material toward the aneurysm. The conduit body includes a first flexibility zone defining a first average bending stiffness and a first outer diameter. The conduit body further includes a second flexibility zone distal to the first flexibility zone and defining a second average bending stiffness and a second outer diameter. The second average bending stiffness and the second outer diameter are less than the first average bending stiffness and the first outer diameter, respectively. The conduit body also includes a transition zone between the first and second flexibility zones. The transition zone defines a third outer diameter that transitions proximally-to-distally from the first outer diameter to the second outer diameter.

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.
