description Microbobina de armazón (102) para su uso en el tratamiento de un trastorno vascular (202), comprendiendo la microbobina (102): una parte sustancialmente esférica (104) formada a partir de una bobina primaria (304) formada por un alambre enrollado helicoidalmente, comprendiendo la parte sustancialmente esférica al menos dos bucles curvados con forma de lóbulo (402) que se cruzan en un punto común (410) en una base de la parte sustancialmente esférica (104), en la que ninguno de los bucles curvados con forma de lóbulo (410) cruza un punto en la parte sustancialmente esférica (104), diametralmente opuesto al punto común. An embolic microcoil can be formed into a complex shape for use in treating aneurysms and other vascular disorders. The microcoil features a distal portion including several loops that together comprise a substantially spherical shape, and an elongated proximal portion that is deployable within the distal portion. The distal portion can create a stable frame with adequate loop coverage across a neck of the aneurysm. The proximal portion can include a series of substantially omega-shaped loops, which can apply a force against the interior of the substantially spherical shaped distal portion, expanding it into apposition with additional portions of the aneurysm wall. Methods of treating vascular disorders and methods of manufacturing certain microcoils are also disclosed.
