IVC Filter

IVC Filters lawsuits are currently being filed against the manufacturers of these devices because they put patients at an unnecessary increased risk of complications.  IVC Filters were designed to prevent blood clots from reaching the heart and lungs but they are failing at alarming rates. Affected individuals require immediate removal and may be left with severe side effects.

Overview of IVC Filters

IVC Filters are spider-shaped devices inserted into the largest vein of the body to capture blood clots and prevent them from reaching the lungs. IVC filters are frequently placed in patients at risk for pulmonary embolism (PE) when anticoagulant therapy cannot be used or is ineffective.

Although the original indication was to use IVC filters after anticoagulant therapy fails, increasingly IVC Filters are being used before exhausting anticoagulant therapy, in a prophylactic manner. Critics believe the use of IVC Filters in this manner puts patients at an unnecessary increased risk of complications from IVC Filters.

Eleven companies sell IVC Filters in the US. An increase in the use of retrievable filters has coordinated with an increase in revenue for the manufacturers of IVC filters, as retrievable filters are more expensive. Retrievable filters represent approximately 75% of the IVC filter market.

Types of IVC Filters

Below are several of the IVC filters that can be found implanted in US patients:

  • ALN Filters
  • Bard IVC Filters include – Bard Denali, Bard Eclipse, Bard G2, Bard G2X, Bard Meridian, Bard Recovery, Bard Simon Nitinol
  • Braun Vena Tech
  • Boston Scientific Greenfield
  • Cook IVC Filters include, Cook Bird’s Nest, Cook Celect, Cook Gunther Tulip, Cordis Optease, Cordis Trapease
  • Rafael SafeFlo
  • Rex Medical Option
  • Volcano Crux


What are Retrievable Inferior Vena Cava Filters?

Retrievable inferior vena cava filters (rIVCF) were designed to prevent blood clots from traveling to the lungs, providing temporary prevention from a pulmonary embolism, and then be removed when a doctor feels that they no longer necessary.

However, many rIVCFs are never removed due to:

  • Poor clinical follow-up
  • Failed retrieval procedures
  • Opportunity for filter removal not offered to patients

Because rIVCFs seem susceptible to greater device-related complications, such as filter penetration of the IVC, filter migration, and filter fracture, in 2010 the FDA was prompted to issue a safety alert urging removal of retrievable inferior vena cava filters once they are deemed no longer necessary.

Vena Cava Filter Side Effects

  • Filter Fracture
  • Penetration and Perforation
  • Migration and Embolization
  • Difficulty Moving the device
  • IVC Thrombosis and Stenosis
  • VTE After IVC Filter Implantation
  • Post-Thromobotic Syndorme

IVC Filter Lawsuits Filed

IVC Filter lawsuits are being filed on behalf of individuals experiencing life-altering complications from IVC Filters.

These lawsuits are being filed against the manufacturers of these devices, including the industry leaders, Cordis Corporation, Cook Medical and C.R. Bard.

IVC Filter use saw a 20-fold increase of use between 1979 and 1999, according to the National Hospital Discharge Survey.   Today, the IVC Filter market is worth $190 million and is growing at a compound annual growth rate of 11% per year.

FDA Alert

FDA Warning Logo In August 2010, The FDA issued a Safety Alert concerning the use of IVC Filters. The FDA recommends that implanting physicians and clinicians responsible for the ongoing care of patients with retrievable IVC filters consider removing the filter as soon as protection from PE is no longer needed.

IVC Filter Complications Increase as the Use of Filters Increase

According to the FDA, the scope of the IVC Filter complication problem has increased rapidly because of the increase use of IVC filters. In 1979, 2,000 IVC Filters were used and by 2012, that number had increased to nearly 260,000

In addition to the increased use of IVC Filters, retrievable filters are remaining in the body for longer periods of time, beyond the time when the risk of pulmonary embolism has passed.

In 2010, the FDA encouraged all physicians involved in the treatment and follow up of IVC filter recipients to consider the risks and benefits of filter removal for each patient and to recommend removal as soon as it is feasible.

In May 2014, the FDA updated their initial safety communication to include new research and studies as they became aware of them. The FDA noted that they had become aware of reports from individuals experiencing the following IVC filter side effects:

  • Device migration
  • Filter fracture
  • Embolization (movement of the entire filter or fracture fragments to the heart or lungs)
  • Perforation of the IVC
  • Difficulty removing the device

According to the FDA, these complications have led to further adverse events including lower limb deep vein thrombosis and IVC occlusion. The FDA renewed their concern that retrievable IVC filters are not being removed when the risk outweighs the benefit and mad several recommendations to implanting physicians and clinicians for the ongoing care of patients with retrievable IVC Filters.  Specifically, physicians should:

  • Consider the risks and benefits of filter removal for each patient
  • Consider removing the filter as soon as protection from pulmonary embolism is no longer needed

IVC filters are removed in a process similar to the way they were placed, but in some instances, surgeons have been unable to retrieve the filters, and patients have experienced life-threatening side effects such as filter migration, organ perforation, and heart embolization.

The FDA also encouraged all physicians involved in the treatment and follow-up of patients receiving IVC filters to refer patients for IVC filter removal when the risk/benefit profile favors removal and the procedure is feasible given the patient’s health status.

According to a 10-year study published in the medical journal Pediatric Radiology, researchers found that it may be difficult for doctors to remove IVC filters from children, particularly when the filters tilt or migrate out of position or become embedded in internal organs.

IVC Filter Complications

blue arrow

Filter Fracture

Separation of any component of the filter due to structural failure. Accounts for up to 22% of complications reported in the MAUDE (Manufacturer and User Facility Device Experience) database.

blue arrow

Penetration and Perforation

Visualization of one of more filter struts beyond the cava wall or within an adjacent structure. Accounts for up to 20% of complications reported in the MAUDE database.

blue arrow

Migration and Embolization

Movement of the device beyond the location of initial placement within the IVC. Accounts for 22% of complications reported in the MAUDE database.

blue arrow

IVC Thrombosis and Stenosis

Formation of chronic DVT in the IVC secondary to prolonged IVC Filter implantation. Increased risk with prolonged implantation and absence of therapeutic anticoagulation.

IVC Filter Frequently Asked Questions

There are no IVC Filter Class Actions.  Instead, IVC Filters lawsuits are currently being filed against the multiple manufacturers of IVC Filters including – the largest of which are Cook and Bard.  These individual cases are being grouped together so the attorneys and judge can address common procedural issues initially, saving time for the injured parties and the court, but this is very generally referred to as a “mass tort.”

A mass tort refers to civil actions involving numerous plaintiffs against one or a few corporate defendants in state or federal court. Class actions are mass torts that are generally used on financial losses and multidistrict litigations (MDL) are generally used on personal injury claims, often in product liability cases

MDL is a procedural tool used when plaintiffs have incurred injuries from products manufactured by the same defendant(s). Even when plaintiffs incur injuries from the same defendant(s), the amount of damages they may recover for those injuries are often substantially different from other plaintiffs included in the same lawsuit.

The two current IVC Filter MDLs are

  • In Re:Bard IVC Filters Products Liability Litigation MDL No. 2641 in the US District Court for the District of Arizona
  • In Re:Cook Medical, Inc., IVC Filters Marketing, Sales Practices and Products Liability Litigation, MDL No. 2570 in the U.S. District Court, S.D. West Virginia.

A number of IVC Filter Lawsuits filed against Cordis Corporation were  dismissed based on the fact that CA does not permit design defect claims.  We will keep victims posted as to the progress with the Cordis IVC Filter lawsuits.
