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.

24. An aneurysm buttressing arrangement for covering an aneurysm opening in an intracranial aneurysm, for temporary placement there adjacent, to prevent escape of embolitic agents from that aneurysm, said arrangement comprising:
-
an elongated delivery wire having a proximal end and a tracking distal end wire;
a scaffold including a collection of circumferentially spaced helically directed expandable wires arranged proximal to and in spaced adjacent relationship to said distal end of said delivery wire, wherein said scaffold has a tapered proximal end and a tapered distalmost end, wherein said scaffold is expandable upon deployment from a delivery catheter, collapsible for withdrawal into a delivery catheter, and detachable from said elongated wire;
said tracking distal end extending distally from said scaffold one to three centimeters.

26. A method of buttressing an intracranial aneurysm in a vessel wall, comprising the steps of:
-
transluminally positioning a scaffold of wires out of a delivery catheter, said scaffold having a proximal end and a distal end arranged onto a near distal of a delivery wire across the opening of an aneurysm;
inserting a balloon within said scaffold expanding said scaffold from a first contracted diameter to a second diameter to engage said vessel wall by expanding a helically wound wire comprising said scaffold with said balloon;
introducing an embolitic agent into said aneurysm through a cell between adjacent wires comprising said scaffold;
permitting blood to flow through said cells of said scaffold subsequent to said introduction of said embolitic agent into said aneurysm; and
withdrawing said scaffold from its position adjacent said aneurysm.

27. A method of buttressing an intracranial aneurysm in a vessel wall, comprising the steps of:
-
transluminally positioning a scaffold of wires out of a delivery catheter, said scaffold having a proximal end and a distal end arranged onto a near distal of a delivery wire across the opening of an aneurysm, said delivery wire having a central lumen therethrough;
expanding said scaffold from a first contracted diameter to a second diameter to engage said vessel wall by expanding a helically wound wire comprising said scaffold;
placing a control wire through said lumen in said delivery wire;
introducing an embolitic agent into said aneurysm through a cell between adjacent wires comprising said scaffold;
permitting blood to flow through said cells of said scaffold subsequent to said introduction of said embolitic agent into said aneurysm; and
withdrawing said scaffold from its position adjacent said aneurysm. - View Dependent Claims (16, 20, 21, 22, 23)
