Event Description
|
As reported by the legal brief, the patient underwent placement of trapease vena cava filter.The filter subsequently malfunctioned and caused injury and damages to the patient, including, but not limited to, pulmonary emboli, blood clots, clotting and occlusion of the lvc filter.As a direct and proximate result of these malfunctions, the patient suffered life-threatening injuries and damages, and required and will continue to require extensive medical care and treatment.As a further proximate result, the patient has suffered and will continue to suffer significant medical expenses, and pain and suffering, and other damages.

As reported, the patient underwent placement of trapease vena cava filter.The filter subsequently malfunctioned and caused injury and damages to the patient, including, but not limited to, pulmonary emboli, blood clots, clotting and occlusion of the inferior vena cava (ivc) filter.As a direct and proximate result of these malfunctions, the patient suffered life-threatening injuries and damages, and required and will continue to require extensive medical care and treatment.As a further proximate result, the patient has suffered and will continue to suffer significant medical expenses, and pain and suffering, and other damages.The product was not returned for analysis.Additionally, as the sterile lot number was not available, device history record review could not 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.Blood clots and occlusion of the ivc filter does not represent a device malfunction.Recurrent pulmonary embolism is a known potential complication of filter implantation and is listed in the instructions for use (ifu) as such.Clinical factors that may have influenced the event include patient, pharmacological and lesion characteristics.Based on the minimal information provided, it is not possible to draw a clinical conclusion or determine a root cause for the reported event.Given the limited information available for review at this time, there is nothing to suggest that the reported event is related to the design, manufacturing process or implantation of the device; therefore no corrective action will be taken.Should additional information become available, the file will be updated accordingly.

Manufacturer Narrative

After further review of additional information received, the following sections have been updated accordingly.Additional information received per the medical records indicate that the patient has a history of deep vein thrombosis, diabetic ketoacidosis and chest pain.A pre-procedural radiological exam revealed the patient had pulmonary embolism involving proximal right and left pulmonary arteries, left upper and lower lobe segmental arteries and right lower lobe segmental artery.There was some nonocclusive thrombus within the proximal right pulmonary artery and left lower lobe focal interstitial disease was also present.According to the patient profile form (ppf) the filter has been in place for more than 90 days and it is too risky to attempt retrieval and future perforation and fracture are likely.It also states that the patient experienced fear and that the patient has experienced multiple post-procedural pulmonary embolisms which have cause hospitalization and stroke.Additional information is pending and will be submitted within 30 days of receipt.

After further review of additional information received, the following sections have been updated accordingly.The expiration date is november 2007.As reported, the patient underwent placement of trapease inferior vena cava (ivc) filter.Per the medical records, the patient has a history of deep vein thrombosis, diabetic ketoacidosis and chest pain.A pre-procedural radiological exam revealed that the patient had pulmonary embolism involving proximal right and left pulmonary arteries, left upper and lower lobe segmental arteries and right lower lobe segmental artery.There were some nonocclusive thrombus within the proximal right pulmonary artery and left lower lobe focal.Interstitial disease was also present.There are no implant procedure details available.The filter subsequently malfunctioned and caused injury and damages to the patient, including, but not limited to, pulmonary emboli, blood clots, clotting and occlusion of the lvc filter.Per the patient profile form (ppf), the filter has been in place for more than 90 days and it is too risky to attempt retrieval.It also states that the patient experienced fear and multiple post-procedural pulmonary embolisms and stroke.The filter remains implanted; thus, unavailable for analysis.The product was not returned 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.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.Blood clots, clotting, pulmonary emboli and occlusive thrombosis within the filter do not represent a device malfunction.Stroke is a known potential adverse event associated with the use of the ivc filters and does not represent a device malfunction and is probably related to the underlying coagulopathy issue specific to the patient.Anxiety does 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.
