Patent ID: 7608088

Claim:
An aneurysm treatment device comprising: an expandable anchoring element exhibiting the characteristic of expanding against the walls of a vessel when unrestrained and having proximal and distal ends; a restraining framework defining a curving sidewall and a central point attached to the distal end of said expandable anchoring element, said restraining framework having apertures within said framework sidewall to permit the passage of embolic devices and adapted to be positioned with an aneurysm; wherein the restraining framework takes the form of a wire basket of a hemispherical configuration; said expandable anchoring element being capable of providing a radial force on the vessel to prevent movement and migration of said framework; said expandable anchoring element permitting passage of embolic devices to and through said apertures within the sidewall of said framework; and at least one embolic device in contact with and retained by said framework to thereby hold the embolic device within the aneurysm.
