Abstract

The vasoocclusive apparatus can be used in a method of interventional therapy and vascular surgery by inserting the apparatus into a portion of a vasculature, for treatment of a body vessel such as an aneurysm in conjunction with a secondary vasoocclusive device to be placed within the vessel. The vasoocclusive apparatus includes a plurality of strut members connected together at a central hub that extend from a collapsed position to an expanded configuration to cross the neck of the aneurysm, dividing the neck into smaller openings, allowing the deployment of the secondary vasoocclusive device within the aneurysm but preventing migration of the secondary vasoocclusive device from the aneurysm. The strut members can be made from a twisted cable of strands of a superelastic material, such as a shape memory nickel titanium alloy, with at least one radiopaque strand. A shape memory collar is provided for detachably mounting the vasoocclusive apparatus to a pusher member and for detaching the vasoocclusive apparatus for deployment when a desired placement within an aneurysm to be treated and out of a parent vessel is achieved.
