1. An aneurysm device endovascularly deliverable to a site proximate an aneurysm near a terminus of a parent artery with bifurcating downstream arteries, the aneurysm device comprising:

  • a closure structure comprising;

    a distal-facing aspect configured to at least partially occlude the aneurysm and a proximal-facing aspect configured to arch over lumina of the downstream arteries,wherein the closure structure is configured to span unobtrusively over the lumina and forms no incursion onto the vascular flow path;

    a barrier supported by at least the distal-facing aspect; and

    a supplemental stabilizer connected to the closure structure, the supplemental stabilizer configured to reside in the parent artery and press outward against a luminal wall thereof;

    wherein the closure structure further comprises a distal framework portion having a lateral axis orthogonal to the supplemental stabilizer, wherein opposing lateral faces of the distal framework portion are biased away from the lateral axis to press against the parent artery;

    wherein the supplemental stabilizer has a proximal framework portion, and the lateral axis of the distal framework portion comprises a vertex from which the proximal framework portion is biased to press outward against a luminal wall of the parent artery.
