Manufacturer Narrative

As reported, the patient underwent placement of a trapease inferior vena cava (ivc) filter.The indication for filter placement is not available.An x-ray was done approximately fifteen years and nine months after the index procedure.The x-ray image indicates that there were fractures of several filter struts.Approximately sixteen years after the index procedure, the device was removed.However, several struts migrated and remain in the patient's right ventricle and lung.The device is not available for analysis.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 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.The instructions for use (ifu) states 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.Inferior vena cava (ivc) filter migration is a known potential adverse event associated with all ivc filter implants and is listed in the instruction for use (ifu) as such.Possible causes for filter migration include mega cava, wire entrapment during central venous catheter placement, ¿sail¿ effect (cranial migration) of large clot burden within the filter, mechanical device failure, and operator error.Physiologic causes of migration may result from temporary dysmorphism of the inferior vena cava including bending, coughing or valsalva maneuvers resulting in dislodgment of the filter.Some studies suggest that strenuous physical activity and increased intra-abdominal pressure can lead to migration of ivc filters.Anxiety and pain do not represent a device malfunction and may be related to underlying patient related issues.Clinical factors that may have influenced the event include patient, pharmacological and lesion characteristics.Without procedural films or images for review the reported event(s) could not be confirmed.Given the limited information available for review at this time, 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.

Event Description
|
As reported by the legal brief, the patient underwent placement of the trapease vena cava filter. an x-ray was done approximately fifteen years and nine months after the index procedure.The x-ray image indicates that there were fractures of several filter struts.Approximately sixteen years after the index procedure, the device was removed.However, several struts remained in the patient's right ventricle and lung.As a direct and proximate result of the fractured device, the patient has suffered bodily injury, pain, suffering, disability, disfigurement, mental anguish, loss of capacity for enjoyment of life, expense of medical care and treatment, and will require ongoing medical care and monitoring for the rest of their life.
