The lot history record of the reported lot number was reviewed and no discrepancies that might have caused the reported event were noted.The pipeline device will not be returned for evaluation as the tip coil remains in the patient and the remainder was discarded at the site.The complaint could not be confirmed, and the event cause could not be determined.Per pipeline instructions for use: "the pipeline (tm) embolization device (ped) is indicated for the endovascular treatment of adults (22 years of age or older) with large or giant wide-necked intracranial aneurysms (ias) in the internal carotid artery from the petrous to the superior hypophyseal segments." in this case, the pipeline embolization device was used to treat a vertebral artery aneurysm.

Medtronic (covidien) received report that a pipeline tip coil detached and remains in the patient.The patient was being treated for an unruptured fusiform aneurysm in the left vertebral artery.At deployment, the physician rotated the pushwire five times to detach.As the pipeline was being deployed, the tip coil could not travel further due to vessel terminus and the tip coil detached into the aneurysm.Detached segment was 15mm in length.A second pipeline was used to trap the tip coil.Post-procedure angiography shows that the tip coil is trapped mostly in the aneurysm with a portion trapped on vessel wall.The patient is reportedly in normal condition.
