Claims12
A aneurysm occlusion device, comprising:
- an expandable liner for delivery within an aneurysm;
- and
- a first extender coil disposed within said expandable liner, said first extender coil having a restrained shape in axial alignment with a delivery device when restrained by said delivery device, and a curved relaxed shape when removed from the delivery device such that said first extender coil bears against the expandable liner causing the expandable liner to expand toward the walls of an aneurysm.
An aneurysm occlusion device, comprising:
- an elongated delivery catheter having a proximal end, a distal end and a lumen therethrough;
- an expandable liner for delivery within an aneurysm, said expandable liner detachably connected to the distal end of said elongated catheter;
- a guidewire extending through said lumen of said delivery catheter and into said expandable liner;
- a first extender coil disposed within said expandable liner and over said guidewire, said first extender coil having a restrained shape in axial alignment with said guidewire when restrained by said guidewire, and a curved relaxed shape when said guidewire is withdrawn from said first extender coil such that said first extender coil bears against the expandable liner causing the expandable liner to expand toward the walls of an aneurysm.
