Abstract: In some examples, an embolization device includes multiple sections with three-dimensional non-helical structures when deployed at a vascular site. The multiple sections include a first section and one or more second sections that are smaller than the first section. The first section may have a deployed structure configured to anchor the device at a vascular site (e.g., a blood vessel) of a patient while each of the one or more second sections may be formed from loops that configured to pack and obstruct the vascular site. In some cases, the embolization device also includes a third section having a deployed configuration with multiple helical windings or loops is configured to anchor the embolization device at the vascular site.

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.
