Manufacturer Narrative

It was reported that a patient underwent placement of an unspecified cordis vena cava filter.The information provided indicated that the filter subsequently malfunctioned and caused filter fracture.The indication for the filter placement and pertinent medical records have not been provided.There is currently no additional information available for review.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.An inferior 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 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.Without images available for review the reported event could not be confirmed or further clarified.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.

Manufacturer Narrative

It was reported that a patient underwent placement of an unspecified cordis vena cava filter.The information provided indicated that the filter subsequently malfunctioned and caused filter fracture.The patient reported becoming aware of filter fracture within the inferior vena cava (ivc) and perforation of filter struts outside the ivc, approximately eleven years and two months post implant.The patient also reported sciatica, pain, numbness, right leg pain to the foot and swelling.According to the implant record the indication for the filter implant was right sided empyema and pulmonary emboli.Following a right posterolateral thoracotomy with decortication and pleurectomy and placement of on-q pain pump catheters, the ivc filter was placed via the right femoral vein and deployed below the takeoff of the renal veins and above the iliac bifurcation.The product remains implanted and unavailable for analysis.A review of the device history record revealed no anomalies during the manufacturing and inspection processes that can be associated with the reported complaint.An inferior 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.Vessel perforation is a known adverse event associated with implanting vena cava filters and is listed as such in the instructions for use (ifu).The ifu notes vessel damage such as intimal tears and perforation as procedural and long-term complications related to ivc filters.Without images available for review the reported events could not be confirmed or further clarified.The ifu also 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.Without images available for review the reported event could not be confirmed or further clarified.Sciatica and associated symptoms, s caused by pinching of the sciatic nerve usually from a herniated disc, this does not represent a device malfunction and may be related to underlying patient specific issues and other undisclosed comorbidities.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.

Event Description
|
Additional information received per the medical records indicate that the patient has a history of right-sided empyema and pulmonary embolism (pe).The patient was scheduled for the following procedures: right thoracotomy with decortication, pleurectomy, placement of two on-q pain pump catheters and placement of inferior vena cava (ivc).After the other procedures the filter was implanted via the patient's right femoral vein.The filter was deployed below the renal veins takeoff and above the iliac bifurcation.The patient was hemodynamically stable after the procedures.Additional information received per the patient profile form (ppf) states that the patient experienced filter fracture within the inferior vena cava (ivc) and perforation of filter struts outside the ivc.The patient became aware of the reported events approximately eleven years and two months after the index procedure.The patient also experienced sciatica, pain, numbness, right leg pain in foot and swelling.
