Neurovascular embolization device. The Optima Coil System is a series specialized coils that are inserted into the vasculature under angiographic visualization to embolize intracranial aneurysms and other vascular anomalies. The system consists of an embolization coil implant comprised of platinum/tungsten, affixed to a delivery pusher to facilitate insertion into the hub of a microcatheter. The system is available in various shapes, lengths and sizes. The devices are to be placed into aneurysms to create blood stasis, reducing flow into the aneurysm and thrombosing the aneurysm. Upon positioning coils into the aneurysm, the coils are thermally detached from the delivery pusher in serial manner until the aneurysm is occluded. There are a total of 208 Optima Coil models.

Discoloration was identified along the delivery pusher which was attributed to corrosion of the hypotube. The material which caused the corrosion was identified as remnants of solder flux residue remaining on the hypotube component of the delivery pusher. Due to the location of the delivery pusher within the delivery system, it is possible for the discoloration to mechanically break off from the delivery pusher, leaving the potential for the material to flow through the delivery system (i.e. microcatheter), and into the patient vasculature causing foreign emboli.
