As reported by the legal brief, a patient underwent placement of a trapease vena cava filter.The filter subsequently malfunctioned and caused injury and damage to the patient, including, but not limited to, volar tilting of the filter by 14 degrees resulting in the superior tip touching the anterior wall of the inferior vena cava (ivc).The device was not returned for analysis.No lot number was provided therefore a product history record (phr) review could not be generated.The reported ¿filter-tilt¿ could not be confirmed as the device was not returned for analysis.The exact cause of the reported events could not be conclusively determined.Procedural/handling factors, or vessel characteristics, although unknown, may have contributed to the reported events.According to the ifu, which is not intended as a mitigation of risk, ivc filter tilt has been associated with the anatomy of the vessel, specifically asymmetry and tortuosity.Without images available for review, the reported tilt could not be confirmed or further clarified.The timing and mechanism of the tilt has not been reported at this time.Due to no lot number being provided, a phr could not be generated.The limited information available does not suggest a design or manufacturing related cause for the reported event; therefore, no corrective/preventive action will be taken at this time.Should additional information become available, the file will be updated accordingly.
