Patent ID: 8057495

Claim:
A system for occluding an aneurysm formed in a dilatation area of a body vessel, the system comprising: a wire guide with a proximal end and a distal end, the wire guide having a passageway that extends from the proximal end to the distal end; a core wire with a distal end and a proximal end, the core wire being disposed through the passageway so that the proximal end of the core wire proximally extends beyond the proximal end of the wire guide; and a plurality of occlusion devices in contact together and disposed in series in the passageway of the wire guide and having a distal end and a proximal end, the occlusion devices having a deployed state and an undeployed state, the occlusion devices having a pre-set spiraled coil shape and having different outside diameters when in the deployed state in the vessel, the occlusion devices being disposed distally from the core wire in the passageway, the core wire being configured to move the occlusion devices for deployment over the aneurysm of the body vessel to interfere with blood flow in the aneurysm.
