Abstract:
1. An exclusion device comprising: a shell comprising a proximal hollow stem, and a distal hollow stem and at least two lobes separated by a waist, wherein the waist is narrower than the at least two lobes, and wherein the shell is capable of containing pressure; a pressure tube comprising a pressure port, wherein the distal hollow stem of the shell is attached to a distal tip of the pressure tube and wherein the pressure port communicates pressure to the inside of the shell; a pusher tube; and a guidewire, wherein the guidewire is in contact with an inner diameter of the distal tip of the pressure tube in which the shell in the compacted shape is delivered to an endovascular deployment site; wherein the shell is capable of transitioning from a manufactured shape to a compacted shape to a pressure-expanded shape to a mechanically collapsed shape, wherein the mechanically collapsed shape is formed when the shell is collapsed reducing the at least two lobes to at least two closely-spaced disks as a result of the convergence of the distal tip of the pressure tube and the distal tip of the pusher tube as the pressure tube is pulled proximally and the pusher tube is pushed distally and wherein the distal hollow stem of the shell and the distal tip of the pressure tube are disconnected by continuing the convergence until the force generated tears the pressure tube from the at least two closely-spaced disks.
