Manufacturing review: 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.Investigation summary: the device was not returned for evaluation.Medical records were provided and reviewed.Approximately ten years and nine months of post deployment, computed tomography of abdomen without contrast was performed for stabbing mid abdominal pain and occasional rib pain which revealed there was an inferior vena caval filter present in place.The tip of the filter lies inferior to the level of the renal veins.Many of the struts extend beyond the wall of the inferior vena cava.Therefore, the investigation is confirmed for perforation of inferior vena cava (ivc).Based on the available information, the definitive root cause is unknown.Labeling review: 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: 02/2012.
