UPDATE: $3.6 Million Awarded in IVC Filter Trial
April 2018 — C.R. Bard has been ordered to pay $3.6 million to a woman who needed open-heart surgery when her IVC Filter tilted, migrated, fractured, and broken pieces punctured through her veins and traveled to her heart. Click here to read more.
Over 7,000 IVC Filter Lawsuits Filed Nationwide
There are now over 7,00 IVC Filter lawsuits pending against C.R. Bard and Cook Medical in two federal courts in Arizona and Illinois. Hundreds of additional lawsuits are also pending against B. Braun, Rex Medical, Argon Medical, and other manufacturers.
NBC News Investigation Questions Safety of IVC Filters
An investigation by NBC News reviewed internal documents showing that C.R. Bard was concerned about the safety of the G2 filter within 4 months of its approval, but continued to sell 160,000 of the devices over the next 5 years.
In 2015, another investigation with NBC News questioned the safety and possibly forged approval of C.R. Bard’s Recovery IVC filter. In the last decade, 27 deaths and 300 non-fatal adverse events have been linked to the device.
The G2 has been linked to at least 12 deaths and hundreds of adverse events, suggesting it may have similar problems as the Recovery filter.
What is an IVC Filter?
An IVC filter (also known as a vena cava filter or blood clot filter) is a device that catches blood clots before they enter the lungs and cause a pulmonary embolism. It is implanted in the inferior vena cava (IVC), which is a vein that carries “blue” blood from the body to the lungs to receive oxygen. IVC filters are mostly implanted in patients who can’t use blood-thinning drugs.

FDA Safety Warning
In August 2010, the FDA issued a Safety Communication after receiving nearly 1,000 reports of IVC filter injuries since 2005, often due to temporary filters that were not removed. In 2014, the FDA updated this warning to recommend removing the filters within 29-54 days, if possible.
Stronger Safety Warnings in Other Countries
Other safety warnings have been issued by Health Canada and the Australian Therapeutic Goods Administration (TGA). These agencies have asked hospitals to identify patients who have received IVC filter sand develop formal follow-up plans to remove the filter. Canada also says the filters should only be implanted in patients who cannot take blood-thinning medications, and only if they have also been diagnosed with blood clots in their legs or lungs.
Can an IVC Filter Move?
Yes. Blood clot filters can move, migrate, tilt, out of position, and get stuck where it is not supposed to be. This could cause it to become ineffective to protect against blood clots. It is often impossible to remove. In rare cases, the entire filter moves to the heart and causes sudden death.
IVC Filter Migration Symptoms
IVC filter migration symptoms include chest pain, low blood pressure (hypotension), irregular heart rhythm (arrhythmias), neck pain, confusion, feeling light-headed, nausea, shortness of breath, fainting, or loss of consciousness.
Vena Cava Perforation
The inferior vena cava is the largest vein in the body, but its walls are very thin. The sharp needle-like legs of an IVC filter can perforate the vena cava and cause internal bleeding. The filter may also be impossible to remove when it is stuck in the blood vessel.
IVC Filter Fracture & Embolization
Temporary vena cava filters were never studied for permanent implantation. When they fracture, the needle-like wire legs break off and travel in the bloodstream (called “embolization”) until they get stuck in the heart, lungs, or other blood vessels. This can cause severe organ damage. For example, doctors at Baylor University published a case report of a young woman who experienced severe complications when a Bard G2 IVC filter fractured after it was was left in her body for more than 6 years.
IVC Filter Thrombosis
Blood clot filters are designed to catch blood clots. In some cases, the filter becomes clogged. This can block blood-flow between the lower half of the body and the heart. Over time, circulation problems significantly increase the risk of Deep Vein Thrombosis (DTV). Long-term complications include chronic pain, swelling, ulcers, and circulation problems in the legs.
IVC Filter Removal Surgery
All temporary IVC filters should be removed. However, when complications occur, it is not always possible to remove the filter with minimally-invasive surgery. Patients may need invasive open-heart surgery. However, most of the time surgeons will leave a broken filter embedded in the patient because surgery to remove it is more risky than leaving it implanted.
IVC Filter Deaths Classified as “Malfunctions”
In July 2015, the FDA sent a warning to C.R. Bard after finding that the company was mistakenly classifying serious injuries and deaths as “device malfunctions.” In one report, a G2 filter broke and the detached filter arm caused severe bleeding, lung damage, and death.
When Should an IVC Filter Be Removed?
The longer an IVC filter remains implanted, the higher the risk of complications. The FDA recommends removing the filters within 29-54 days after implantation, or as soon as the patient can take a blood-thinning medication. Even so, studies indicate that less than 30% of IVC filters are ever removed. Fewer than 10% are removed from trauma patients.
C.R. Bard MDL
As of December 2016, over 1,100 IVC filter lawsuits against C.R. Bard were centralized into a Multi-District Litigation (MDL No. 2641) in the U.S. District Court for Arizona under U.S. District Judge David G. Campbell.
C.R. Bard IVC Filter Class Action
In addition to personal injury cases, the MDL also includes a class action for everyone who was implanted but not injured by a blood clot filter made by C.R. Bard. Lawyers are seeking compensation for everyone who needed follow-up medical care due to the high risk of side effects.
Cook Medical MDL
As of December 2016, nearly 1,200 IVC filter injury lawsuits against Cook Medica were centralized into one federal court in the Southern District of Indiana under Judge Richard L. Young (MDL No. 2570) in 2014.
IVC Filter Trials
In 2012, a state-court jury in Arizona cleared C.R. Bard of wrongdoing in the first IVC filter trial. The next IVC filter trial is scheduled for 2017, and will involve the Celect IVC filter made by Cook Medical. The second trial will involve the Günther Tulip IVC filter, also made by Cook Medical.
IVC Filter Settlement Amount
In February 2015, C.R. Bard reached a settlement with a man who underwent emergency surgery to remove a Recovery filter. The amount of the settlement was not disclosed publicly. Our lawyers are pursuing lawsuit settlements and cash payouts for people who were injured by IVC filters.
IVC Filter Lawsuits
Over 2,000 lawsuits have been filed by people who were injured by blood clot filters. Many cases involve severe complications like open-heart surgery and wrongful death. Some victims still have broken pieces of the filter in their body because they were too dangerous to remove.
IVC Filter Lawsuit Statute of Limitations
The statute of limitations for an IVC filter lawsuit depends on the state where you live. In some states, this time-limit is 1 year from the date of your injury. In other states, it is up to 6 years. The deadline can be much longer if a manufacturer concealed side effects, so it is always a good idea to talk to a lawyer if you think you might have a lawsuit.
Experts Question IVC Filter Safety Risks vs. Benefits
Experts are raising concerns about over-hyped and under-studied IVC filters, especially the lack of studies proving they actually improve patient survival, ongoing design challenges, and no consensus about when they should be used. According to Dr. Joseph Stavas:
“[IVC filters] were thought of as a savior for many surgeons, but eventually became a crutch for managing patients with thrombosis, providing a false sense of security.”
In March 2013, JAMA published an editorial titled “How could a medical device be so well accepted without any evidence of efficacy?” Since then, several studies have confirmed that IVC filters have serious risks and questionable benefits:
- September 2016 — Study finds no survival benefit for trauma patients implanted with IVC filters, and only 8% were retrieved within the 3.8-year follow-up.
- November 2015 — Study finds that trauma patients who are implanted with an IVC filter are no more likely to survive, but 83% more likely to develop blood clots in the legs (deep vein thrombosis).
- August 2015 — Study links Cook Medical’s Celect IVC filter with a 43% rate of vena cava perforation, compared to a 0% rate for the Option filter made by Rex Medical (Argon Medical).
- April 2015 — Study finds that patients at risk of a blood clots might not benefit if they are implanted with a retrievable inferior vena cava (IVC) filter instead of using a blood-thinning medication.
Bard Recovery, G2 IVC Filters Linked Fracture Risk
In August 2010, the Archives of Internal Medicine published a study that found high rates of fracture and fragment embolization associated with the C.R. Bard Recovery (first generation) and the Bard G2 (second generation) IVC filters. Dr. William Nicholson looked at 80 patients who were implanted with the filters between April 2004 and January 2009.
Thirteen out of 80 patients (16%) had at least one strut fracture. In at least five cases, fractured pieces of the filter traveled in the bloodstream and ended up in the heart. Three patients experienced life-threatening heart problems, including one who died suddenly at home. One patient suffered chest pain, fluid build-up around the heart, and perforation of the right ventricle. Fractures occurred in 6 out of 52 patients (12%) with the Bard G2 filter, suggesting it may have similar problems as the Recovery.
IVC Filter Side Effects
Health Canada is warning about serious safety side effects of IVC filters, including:
- Vena cava perforation
- Blood clots
- Fractured filters and embolization of broken pieces
- Migration to the heart
- Perforation of the heart
- Cardiac tamponade
