Manufacturer Narrative

As reported, the patient underwent placement of a trapease vena cava filter.The indication for the filter placement was not reported.At some point after the filter implantation, the patient became aware that the filter had tilted, fractured/bent and was associated with a small bowel perforation.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 trapease vena cava filter is indicated for use in the prevention of recurrent pulmonary embolism (pe) via percutaneous placement in the inferior vena cava (ivc) for patients in which anticoagulants are contraindicated, anticoagulant therapy for thromboembolic disease has failed, emergency treatment following massive pe where anticipated benefits of conventional therapy are reduced or for chronic, recurrent pe 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.Without images or procedural films for review, the reported filter tilt, fracture and small bowel perforation events could not be confirmed and the exact cause could not be determined.Ivc filter tilt has been associated with the anatomy of the vessel, specifically asymmetry and tortuousness.Additionally, the timing and mechanism of the filter tilt is unknown.The timing and mechanism of the fracture has not been reported at this time.The instructions for use (ifu) states that filter fracture is a potential complication of vena cava filters.Anatomic locations that create concentrated stress points from filter deformation (for example, deployment at apex of scoliosis, overlapping of either of the renal ostia, or placement adjacent to a vertebral osteophyte) may contribute to fracture of a particular filter strut.It is unknown if the tilt contributed to the reported perforation.A review of the ifu notes vessel damage such as intimal tears and perforation as procedural complications related to ivc filters.Studies have noted a greater than 80% perforation rate overall, with all filters imaged after 71 days from implantation revealing some level of perforation.Clinical factors that may have influenced the event include the patient¿s pre-existing co-morbidities, pharmacological issues and lesion characteristics.Given the limited information available for review, there is nothing to suggest that a malfunction in 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.

Event Description
|
As reported in 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 physical and emotional damages from tilting of the filter, small bowel perforation, fracture/bent struts and the resultant symptoms.As a direct and proximate result of these malfunctions, the patient suffered life-threatening injuries and damages and required medical care and treatment.As a further proximate result, the patient has suffered and will continue to suffer significant medical expenses, pain, suffering, loss of enjoyment of life, distress and other damages.
