Abstract: An implant for treatment of a vascular space can form open loops and closed loops in separate cycles to provide balanced stiffness and flexibility. Such an implant provides both stability for retention within the vascular space and conformability for mitigating forces on the vasculature. Such a configuration can also provide proper coverage over an opening to a vascular space into which the implant is delivered, for reducing or eliminating flow into or out of the body cavity and promoting occlusion of the vascular space.

Abstract: A distal portion (16) of an elongated body (12) is configured to mate with a distal portion (20) of an interface member (18) mechanically connected to an embolization device (22). The embolization device (22) is additionally attached to the elongated body (12). The elongated body distal portion (16) and the interface member proximal portion (19) may collectively define a protrusion and a recess configured to receive the protrusion to provide the mating. The elongated body (12), interface member (18), and embolization device (22) may be configured for delivery to a vasculature target site, and manipulation of the deployed embolization device (22) may be facilitated by the mating between the elongated body (12) and the interface member (18).
