The device history records have been reviewed with special attention to the raw materials, subassemblies, manufacturing process, and quality control testing.This lot met all release criteria.There was nothing found to indicate there was a manufacturing related cause for this event.The device was not returned for evaluation.The medical records included images.The image review was documented in the medical records.Medical records were provided and reviewed.Approximately, thirteen years and five months of post-deployment, an x-ray abdomen was performed for abdominal and epigastric pain.The study showed that an inferior vena cava filter was noted.There was a questionable displacement of two legs of the inferior vena cava filter.A computed tomography of the abdomen and pelvis was performed for abdominal pain.The study showed that an inferior vena cava filter was noted.Around, one year and three months later, the patient was planned for filter removal.Through the right internal jugular vein approach, a catheter was advanced into the right common iliac vein and cavogram was performed.Endobronchial forceps were used to capture the inferior vena cava filter apex, including the caudally deflected leg and the filter was removed in total.The completion venogram showed no evidence of caval injury or thrombus.Therefore, the investigation is confirmed for the material deformation of the filter.However, the investigation is inconclusive for filter tilt, filter limb detachment and perforation of the inferior vena cava (ivc).Based on the available information, the definitive root cause is unknown.A review of product labeling documents (e.G.Procedural instructions, indications, warnings, precautions, cautions, possible complications, contraindications, and unit label) showed that the product labeling is adequate.(expiry date: 06/2007).
