Doctors have used implantable medical devices known as IVC filters to catch blood clots in the inferior vena cava—the body's longest vein—of trauma patients or obese surgical patients since the first form of the device was approved by the U.S. Food and Drug Administration (FDA) in the early 1980s.
Today, there are a number of IVC filter types, brands, and models on the market. While any of these devices carry some risk, certain brands and models have been named in lawsuits. Read on to learn more about the various types of IVC filters, as well as which manufacturers are being sued and what you can do if you suffered serious IVC filter-related complications.
Permanent IVC Filters
Permanent IVC filters are small yet sturdy cage-shaped devices surrounded by wiry legs. These filters are designed to last and can be left in the inferior vena cava indefinitely. The FDA approved the first permanent IVC filter, the Bird's Nest® by Cook Medical, in 1982, followed by:
- Vena Tech LGM® filter by B. Braun in 1989
- Titanium Greenfield® filter by Boston Scientific in 1989
- Simon Nitinol® by C.R. Bard in 1990
- TRAPEASE® filter by Cordis in 2000
- Günther Tulip® by Cook Medical in 2000
- Vena Tech LP® by B. Braun in 2001
- Optease® by Cordis in 2002
- Recovery® by C.R. Bard in 2002
- G2® by C.R. Bard in 2005
- Select® by Cook Medical in 2007
Incidentally, though it wasn't the first IVC filter approved by the FDA, the Boston Scientific's Titanium Greenfield filter proved on of the most popular, leading many in the medical community to use “greenfields” as a catch-all term for IVC filters of all varieties.
Despite being the older type of IVC filters, permanent IVC filters are generally considered more reliable and less prone to cause serious side effects than newer, retrievable IVC filters.
Retrievable or Temporary IVC Filters
By the early 2000s, the FDA had approved several permanent IVC filter to also serve as retrievable or temporary filters to be taken out once the threat of thrombosis-related injury has passed, including the C.R. Bard Recovery Filter, approved as a retrievable filter in 2003 and the G2, which gained retrievable approval in 2005, and the Cook Medical Select, which was approved as a retrievable in 2008.
Manufacturers C.R. Bard, Cook Medical, and Rex Medical also made several IVC filter models that were specifically designed for temporary use and designed to be removed. Retrievable IVC filters include:
- G2 Express® by C.R. Bard, approved in 2008
- G2X® by C.R. Bard, approved in 2008
- Option® by Rex Medical, approved in 2009
- Eclipse® by C.R. Bard, approved in 2010
- Meridian® by C.R. Bard, approved in 2011
- Denali® by C.R. Bard, approved in 2013
- Option Elite® by Rex Medical, approved in 2013
IVC Filter Lawsuits
Although retrievable IVC filters are designed to be removed, many are left in place permanently, which can lead to serious side effects and complications, including blood clots—specifically what the devices were designed to prevent. Patients who've filed IVC filter lawsuits claim the manufacturers failed to properly test their products, and continued to manufacture and market the products, even after becoming aware of the risks associated with their use.
The following IVC filters are currently named in lawsuits:
- Bard Recovery Filter
- Bard G2 Filter
- Bard G2 Express Filter
- Bard Eclipse
- Bard Meridian
- Bard Denali
- Cook Select
- Günther Tulip
