Abstract

An apparatus is provided for treating a vascular malformation. The apparatus includes an orifice section, an intra-vascular-malformation docking section, and a connecting section. The apparatus is configured such that, when unconstrained the orifice section is shaped so as to define an orifice-section curve that winds at least 2.5 turns around an orifice-section central axis at a changing distance from the orifice-section central axis, the intra-vascular-malformation docking section is shaped so as to define a docking-section curve that winds between 0.5 and 2 turns around a docking-section central axis at a changing or constant distance from the docking-section central axis, and a slope of the connecting-section is greater than a slope of the orifice-section. Other embodiments are also described.
