Manufacturing review: a lot history review was performed.This is the only complaint to date for this lot number.Therefore, a device history record review is not required.Investigation summary: the device was not returned for evaluation.Medical records were provided and reviewed.Approximately four months later post filter deployment, the patient scheduled for the filter retrieval, the right internal jugular vein was accessed.An inferior vena cavogram was performed, the pertinent findings was angulation of the inferior vena cava just below the renal veins, presumably near the origin of the right renal vein.Initial maneuvers at grasping the apex with a 2cm snare failed.The 2cm snare was replace with 1.5cm snare and additional maneuvers were failed.It was felt the angulation of the inferior vena cava combined with location of the filter apex was adverse in terms of retrieval.The benston wire was snared below the filter.Next, the hoop was created by snare benston wire was tightened against the collar of the filter and the snared was then pulled cephalad with the 18-french advanced caudad.Unfortunately, even with the snare there was tilt of the filter apex hook outside the sheath.At this juncture, there appeared to be more tilt of the filter.Clearly displaced filter legs from the manipulation.Multiple attempts were made without success.It was felt retrieval was not possible and the procedure was then aborted.Therefore, the investigation is confirmed for the alleged filter tilt, material deformation and retrieval difficulties 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: 02/2015).
