IVC Filter Lawsuit - Legal Claims for Complications and Injuries


An IVC filter lawsuit is a legal claim by a patient who underwent implant surgery and subsequently suffered serious complications. These lawsuits claim that the manufacturer made a defective product and/or failed to warn blood clot patients of foreseeable risks and complications.

At this time, there are thousands of inferior vena cava filters plaintiffs. And many are part of a federal multi-district litigation (MDL) mass tort case.

IVC Filters Manufacturers Sued for Defective Products

Common IVC Filters Injuries

Financial Damages for IVC Filters Injuries

  • Economic damages: compensation for lost wages, loss of future earnings, doctor bills, and other out-of-pocket expenses;
  • Non-economic damages: pain and suffering, mental anguish, and loss of consortium
  • Punitive damages: if the case goes to trial and the plaintiff wins, the jury can order the manufacturer to pay punitive damages as a punishment to the manufacturer

Below our experienced IVC filters lawyers discuss:

IVC filter victims have won million-dollar verdicts.

1. What are the grounds for an IVC filter lawsuit?

There are four potential claims:

  1. Negligence,
  2. Defective design,
  3. Manufacturing defect, and/or
  4. Failure to warn/ improper labeling

The victim is the "plaintiff." The filter manufacturer is the "defendant."

1.1. Negligence

There are four elements in negligence claims. Plaintiffs have to prove all of them to win: 

  1. The defendant(s) owed the plaintiff a duty of care;
  2. The defendant(s) breached that duty of care;
  3. This breach of duty caused the plaintiff's injuries; and
  4. The plaintiff's injuries caused money damages

Medical device makers owe a "duty of care" towards patients. This duty comprises such reasonable measures as:

  • Creating safe and functional devices;
  • Providing adequate instructions to the medical providers;
  • Sufficiently outlining all the side effects and potential hazards; and
  • Receiving all the necessary FDA clearances

It is a breach to fall short of these duties. An IVC filter caused the plaintiff's injury is this statement is true: He/she would not have suffered complications but for the filter.

Finally, victims need to prove they lost money. Evidence typically includes:

  • Medical bills;
  • Past paychecks. These show what earnings patient lost from being too injured to work; and
  • Anything else that can show "pain and suffering"

1.2. Defective design

A defective design means the IVC filter is inherently dangerous. A filter manufacturer is liable when:

  1. A design defect posed a foreseeable risk; and
  2. The device was manufactured and used as intended

This type of liability is called "strict liability." All the plaintiff has to show is the device failed. Plaintiffs do not have to prove negligence. (Plaintiffs may have to show the manufacturer could have designed a less risky filter. It depends on the state.)

These defects may manifest right after implantation. Or weeks or months may pass before patients feel symptoms. One IVC filter design defect is "fracturing." In other words, they are prone to falling apart.

A 2010 article studied patients with a Bard Recovery filter. It reported that 25% of them experienced fracturing.1 Once a filter breaks apart, the pieces can travel. They migrate to other parts of the patient's body. And they can cause perforation, embolisms, and/or death.

Typical evidence to show design defects include:

  • The original filter design schematics; and
  • Expert testimony about the design problems

1.3 Manufacturing defects

A good IVC filter design can fail due to poor construction. The equipment could be faulty or substandard. And human error could have played a part.

Typical evidence of these defects include:

  • Testimony from people who made the filters; and
  • Expert testimony about the filters' defects

Proving medical device makers made a mistake is difficult. They keep their operations very secret. And it may be hard to gather enough evidence.

1.4. Failure to warn (marketing defects, improper labeling)

Medical manufacturers have many responsibilities. This includes instructing doctors on how to use their products safely. And they must disclose their potential complications. This is especially true for any hidden dangers.

Warning labels on the packaging for medical devices should be:

traveling filter
A "failure to warn" about risks is a ground to sue.
  • Easy for doctors to understand;
  • Specific; and
  • Placed conspicuously where the doctor can see it

Typical evidence to show marketing defects includes:

  • The warning labels; and
  • Other information included with the device packaging

2. Who are the defendants being sued?

IVC filter victims typically sue the manufacturer. There are more than a dozen types of filters. But the three main manufacturers include:

  1. Bard
  2. Cook Medical
  3. Boston Scientific (Greenfield)

2.1 Bard

Bard manufactures or has manufactured:

  • Bard Recovery Filter
  • Bard G2 Filter
  • Bard G2 Express / G2x Filter
  • Eclipse Vena Cava Filter
  • Meridian Vena Cava Filter
  • Denali Vena Cava Filter
  • Simon Nitinol Vena Cava Filter

One of the metals that Bard uses is Nitinol. This is an alloy of nickel and titanium.

The FDA issued a Warning Letter to Bard on July 13, 2015. The FDA discussed several concerns:

Bard did not establish procedures to evaluate complaints about certain filters. And Bard did not report information about malfunctioning devices.

2.2 Cook Medical

Cook Medical manufactures or has manufactured:

  • Günther Tulip Vena Cava Filter
  • Cook Celect Vena Cava Filter
  • Cook Celect Platinum

One of the metals that Cook uses is Conichrome. This is an alloy of cobalt, chromium, nickel, molybdenum, and iron.

The FDA received multiple adverse event reports. Two examples are here and here.

2.3 Boston Scientific (Greenfield)

Boston Scientific makes the Greenfield Filter. It is meant to be permanent. It is for patients facing pulmonary embolism. The FDA recalled it for almost a year for a defect.

3. What money can victims recover?

IVC filter victims can sue for both:

  • Economic damages (such as medical bills); and
  • Non-economic damages (such as pain and suffering)

If plaintiffs win at trial, the jury decides the reward. But most cases settle through negotiation.

3.1. Types of compensation

3.1.1. Economic Damages

Economic damages have a monetary value attached to them. Examples include:

  • Medical bills. This includes rehab and home health care (past and future);
  • Lost wages while the plaintiff was too ill to work;
  • Loss of earning capacity while the plaintiff is too ill to work; and
  • Other out-of-pocket expenses that there are receipts for

Some economic damages can be "capped" at a maximum. Every state's law is different.

3.1.2. Non-Economic Damages

Non-economic damages are hard to calculate. They comprise intangible injuries. Examples include the plaintiffs':

  • Mental anguish and emotional distress the filter caused, and
  • Pain and suffering. This includes physical pain from injuries and revision surgeries.

The plaintiff's spouse may also be able to sue. Spouses would claim "loss of consortium." This is when the injury had a direct and negative marital impact. Examples are if the filter caused:

  • Depression,
  • Anxiety, and/or
  • Sexual dysfunction

Factors that help determine non-economic damages are:

Non-economic damages include emotional distress.
  • The plaintiff's prognosis;
  • The type and seriousness of the injuries;
  • How long the recovery will take, if ever;
  • Whether there are permanent injuries;
  • Whether there is chronic pain;
  • The extent the injuries compromise daily activities; and/or
  • The extent the injuries impact family and friends

Some non-economic damages can be "capped" at a maximum. Every state's law is different.

3.1.3. Punitive damages

Punitive damages factor in when there is a trial. If the plaintiff wins, the jury can award punitive damages.

Economic damages pay back plaintiffs for their injuries. So do non-economic damages. But punitive damages are different.

Punitive damages punish the defendants (medical device makers). And they deter other device makers from acting like the defendants.

Punitive damages can be very high. States have their own rules about caps.

3.2. Sample jury awards in IVC filters trials

  • $3.6 million by an Arizona jury: A woman sued Bard for her fractured filter (March, 2018).2
  • $3 million by an Indiana jury: A woman sued Cook Medical for her fractured filter (March, 2019) [2020 UPDATE: The court vacated this verdict and ordered a new trial].3
  • $1.2 million by a Texas Jury: A man sued Cook Medical following organ and blood vessel perforations from his filter (May, 2018).4

4. Is the IVC filter litigation individual lawsuits or class actions?

Victims sue individually. But they get joined in a multidistrict litigation (MDL). MDLs are different from class actions.

filter lodged near spine
IVC filter lawsuits automatically join an MDL lawsuit. This expedites litigation.

MDLs help streamline the pretrial process for all IVC filter cases. But unlike in class actions, each plaintiff keeps his/her attorney. And each case gets transferred back to its original court.

A few MDL cases do go to trial. These are called "bellwether" trials. The results give both sides a starting point for negotiations. Current IVC Filter MDLs include:

Recently, an IVC filter class action from Arizona was joined into an MDL. (Case No. 2:16-cv-01374).

5. Have IVC filters been recalled?

Some have. The Food & Drug Administration (FDA) should not have cleared many of them in the first place.

5.1. The FDA approval process for IVC filters

The FDA uses the 510(k) clearance process to approve or deny IVC filters. The manufacturer does not have to provide clinical or laboratory studies to demonstrate the filter's safety. Instead, the manufacturer has to demonstrate that:

  • There already exists a similar filter on the market; and
  • The new filter has the same intended use as the one currently on the market; and
  • If there are technical differences between the two filters, they do not call into question the safety and effectiveness of the new one

The 501(k) process is efficient. But it has potential pitfalls. If the FDA approves a new IVC filter based on a current IVC filter that then turns out to be defective, chances are the new IVC filter may be defective as well.

5.2. The FDA's monitoring process for IVC filters' safety

Once the FDA approves an IVC filter for commercial use, it relies on patients and doctors to notify the FDA when the device fails. This notification is called an "adverse event report."

If these adverse event reports indicate that the device may be defective, the FDA will send the medical manufacturer a "warning letter." (See a sample of a warning letter to Bard.)

If it turns out the filter is defective, the FDA will recall the device until it gets fixed. (Manufacturers can voluntarily recall their devices as well.)

In 2010, the FDA issued a "safety communication" recommending that IVC filters be removed as soon as the risk of pulmonary embolism is lifted. Following this communication, the use of these filters substantially declined.5

Current and past IVC filter recalls include:

Date Posted


IVC Filters Product

Reason for recall

Termination Date




Greenfield Vena Cava Filter System

Reports of detachment at the bond between the carrier capsule and the outer sheath of the Greenfield Vena Cava Filters with 12 Fr Femoral introducer Systems manufactured before March 10, 2004. If the capsule should detach during an implantation procedure, there is a risk of cardiac and pulmonary embolization.





Greenfield Vena Cava Filter

Certain units within eleven lots of the 12 Fr Greenfield Vena Cava Filter may lack a taper on the braided sheath of the delivery system. The lack of a taper could lead to vessel damage as a result of the sheath catching on the edge of the vein and causing a tear.

5.3. When the FDA recalls your IVC filters

A patient's case is much stronger if his/her attorney can say that the FDA recalled the very device that injured the patient. But even if the FDA has not recalled a particular filter, a plaintiff may still be able to prove that it malfunctioned or was otherwise defective. Relevant evidence would include the plaintiff's medical records and expert medical testimony.

There may also be evidence of shady practices by the manufacturer that suggest it was covering up its knowledge of the filters' risks and complications. (For an example, read the NBC News article, "Did Forged Signature Clear Way for Dangerous Blood-Clot Filter?" (September 3, 2015).)

6. How long do I have to file a lawsuit?

Each state has its own statute of limitations. In most states, victims have two years after the injury to file suit. But it could be less.

Therefore, victims should seek legal counsel as soon as possible. Otherwise, they risk losing out on financial damages.
