Abstract
An aneurysm buttressing arrangement for covering an aneurysm opening in an intracranial aneurysm, for temporary placement thereadjacent, to prevent escape of embolitic agents from that aneurysm. The buttressing arrangement comprises an elongated delivery wire having a proximal end and a distal end. An expandable scaffold of wire mesh is arranged on the distal end of the delivery wire. The scaffold comprises a generally “U” shaped arrangement of wire mesh attached to the delivery wire.

An aneurysm buttressing arrangement for covering an aneurysm opening in an intracranial aneurysm, for temporary placement thereadjacent, to prevent escape of embolitic agents from that aneurysm, said arrangement comprising:
- an elongated delivery wire having a proximal end and a distal end;
- an expandable scaffold arranged on said distal end of said delivery wire, said scaffold comprising a generally “U” shaped expandable arrangement of fluid permeable material secured to said delivery wire.
A method of buttressing an intracranial aneurysm in a wall of a vessel comprising:
- transluminally positioning a compressed, generally “U” shaped expandable scaffold at a distal end of a delivery catheter;
- introducing said distal end of said delivery catheter adjacent a neck of an aneurysm in said wall of said vessel;
- moving said expandable scaffold distally out of said delivery catheter and against said neck of said aneurysm;
- and
- expanding said scaffold into a generally flexible, fluid passable “U”-shaped member.
A method of buttressing an intracranial aneurysm in a wall of a vessel comprising:
- placing a scaffold adjacent said aneurysm;
- creating a central looped opening in said scaffold;
- directing blood through said central opening in said scaffold;
- and
- introducing a embolic material through said opening and into said aneurysm.
