IVC Filter Lawsuit: Device Migration, Perforation & Injury Claims

What IVC Filters Are and Why They Were Implanted

Inferior vena cava filters are small, cage-like metal devices implanted into the vena cava (the large vein returning blood from the lower body to the heart) to catch blood clots that could otherwise travel to the lungs and cause a potentially fatal pulmonary embolism. They are prescribed for patients who cannot tolerate anticoagulation therapy.

Many IVC filters were designed as either permanent or 'retrievable' devices -- the retrievable type intended to be removed once the patient's clot risk subsided. However, studies have shown that retrievable IVC filters are often left in place long beyond their intended duration, increasing the risk of device failure.

IVC Filter Failure Modes and Injuries

The core allegations in IVC filter litigation involve specific mechanical failure modes: filter fracture, where metal struts break and travel through the circulatory system; filter migration, where the device moves from its implantation site; and filter perforation, where the device struts penetrate the vena cava wall or adjacent organs including the heart, aorta, and bowel.

These failures can be asymptomatic (discovered incidentally on imaging) or cause severe injury -- chest pain, pericardial tamponade from fragments entering the heart, bowel perforation, and difficulty or impossibility of filter retrieval. Manufacturers are alleged to have known about these failure rates from clinical data but failed to provide adequate warnings and failed to promptly pursue retrieval in patients with retrievable models.

The Bard and Cook MDLs

IVC filter cases have been consolidated in two major MDLs: the Bard IVC filter MDL in the District of Arizona and the Cook IVC filter MDL in the Southern District of Indiana. Thousands of cases are pending in each MDL. Bellwether trials have been completed with mixed results -- some plaintiff verdicts, some defense verdicts.

Settlement negotiations with both manufacturers have occurred and some cases have settled individually. No global MDL settlement has been announced for either Bard or Cook as of 2026. The litigation dynamics are influenced by appellate rulings on Daubert challenges to expert testimony and causation standards. Related: Bard hernia mesh MDL litigation.

Who Qualifies

Patients who received an IVC filter (any manufacturer) and subsequently experienced: fractured filter struts; filter migration; cardiac or vascular perforation; difficulty or failure during attempted filter retrieval; or who have documented device failure on imaging -- may have claims. Medical records identifying the specific filter brand and model are essential.

Status 2026

Both MDLs are actively litigating. Bard has resolved some cases; Cook has resolved fewer. New cases continue to be filed. No statute of limitations has run for recent injury discoveries. Consult a mass tort attorney specializing in IVC filter cases.

How to Get Legal Help

If you believe you qualify based on the eligibility criteria described above, the next step is a free consultation with an experienced attorney. Most plaintiff-side attorneys handling these cases work on contingency -- meaning you pay nothing unless your case results in a recovery. Bring any relevant documentation including receipts, correspondence, or evidence of the harm you experienced.
