Abstract:
1. A vascular aneurysm exclusion device comprising: a shell having a proximal end, a distal end and at least two lobes separated by a waist, wherein the waist is narrower than the at least two lobes, and wherein said shell is capable of containing pressure; a pressure tube comprising a pressure port near a distal tip thereof and a lumen sized to accept a guidewire therethrough, said distal tip detachably attached to the distal end of said shell, wherein the pressure port communicates pressure to the inside of said shell; and a pusher slidingly positioned over said pressure tube, the pusher having a distal end placed next to the proximal end of said shell; wherein the shell is capable of transitioning from a manufactured shape to a compacted shape over said pressure tube; to a pressure-expanded shape resembling said manufactured shape upon application of pressure through said pressure port of said pressure tube; and finally to a mechanically collapsed shape, wherein the mechanically collapsed shape is formed when the shell is collapsed by a sliding motion of said pusher and said pressure tube causing convergence of the distal end and the proximal end of said shell whereby reducing the at least two lobes to at least two closely-spaced disks.
