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 arrangement comprises an elongated delivery wire having a proximal end and a tracking distal end wire, a scaffold of expandable wires arranged proximal to and in spaced adjacent relationship to the distal end of the delivery wire, wherein the scaffold of wires has a tapered proximal end and a tapered distalmost end, the scaffold being expandable upon deployment from a delivery catheter, and collapsible for withdrawal into a delivery catheter, the tracking distal end wire extending distally from the scaffold about one-half to about ten centimeters.
