As reported a patient underwent placement of the optease vena cava filter.The information provided indicated that the filter subsequently malfunctioned and caused bent struts and calcification seen within the caval filter consistent with old clot material.The indication for the filter, procedural details and patient medical history have not been provided.The product was not returned for analysis and the sterile lot number has not been provided; therefore, no device analysis nor device history record review could be performed.The optease vena cava filter is indicated for use in the prevention of recurrent pulmonary embolism (pe) via percutaneous placement in the vena cava for patients in which anticoagulants are contraindicated, anticoagulant therapy for thromboembolic disease has failed, emergency treatment following massive pulmonary embolism where anticipated benefits of conventional therapy are reduced or for chronic, recurrent pulmonary embolism where anticoagulant therapy has failed, or is contraindicated.The purpose of a vena cava filter is to catch thrombus from the lower extremities as it travels along normal blood flow patterns up towards the heart.Blood clots, occlusive thrombosis of the filter and/or the vasculature do not represent a device malfunction.Clinical factors that may have influenced the event include patient, pharmacological and vessel characteristics.Without the procedural films or post-placement imaging and the limited information provided, the report of old clot material and bent filter struts could not be confirmed or further clarified, nor a clinical determination made.The timing and mechanism of the bent struts was not reported.Given the limited information currently available for review, there is nothing to suggest that the reported events are related to the design and manufacturing process of the device; therefore, no corrective action will be taken.Should additional information become available, the file will be updated accordingly.
