Günther Tulip IVC Filter: What’s The Problem?

The Cook Günther Tulip IVC Filter is a retrievable device that is implanted into the inferior vena cava of patients who are at risk for blood clots, but who are unable to be treated with blood thinning medications. The device’s wire-like struts capture any blood clots that break loose from the deep veins of the legs, thereby preventing the clots from traveling to the lungs and becoming a pulmonary embolism.

Cook has marketed the Günther Tulip IVC Filter in Europe since 1992, and launched the device in the U.S. in 2005. The small, cage-like filter consists of 12 wires, including 4 legs that are each 44-mm in length. The U.S. Food & Drug Administration (FDA) approved the Günther Tulip through the 510(k) clearance program, which does not require that a device manufacturer conduct human tests on a new product that is shown to be “substantially equivalent” in design to another device already approved by the agency.

In recent years, a number of studies and reports have raised disturbing questions about the safety of retrievable IVC filters.

  • August 2010: The FDA disclosed that it had received more than 900 reports involving problems with retrievable filters, some of which resulted in adverse clinical outcomes. The reports included more then 300 cases of filter migration; 146 involving embolization; 70 instances of filter perforation; and 56 report of filter fracture .The agency also advised that many of the incidents may have been related to a retrievable filter remaining in the body long after the risk of pulmonary embolism had subsided.
  • April 2012: A study published in Cardiovascular and Interventional Radiology suggested the Cook Günther Tulip IVC filter was associated with a high risk of vena caval perforation with longer indwelling times. Of 50 patients followed between July 2007 and March 2009, all showed some degree of vena cava perforation within 71 days. Filter tilt was seen in all patients, while at least one component of the filter completely perforated the vena cava in 86% of the patients.
  • May 2014: The FDA issued a second alert regarding the importance of retrieving IVC filters, and recommended that the devices be removed between 29 and 54 days after implantation.

  • February 2016: Cook Medical is seeking a 60-day continuance of a settlement conference scheduled for next month in the federal litigation involving its Celect and Gunther Tulip IVC filters. The company asked for the delay to give its recently retained counsel additional time to review information surrounding the claims and to confer with the company. Read More
  • July 2016: The federal court overseeing hundreds of Cook IVC filter lawsuits has chosen three cases for the litigation’s first bellwether trials, which are to be convened in 2017. According to an Order issued in the U.S. District Court, Southern District of Indiana, one of those cases, Gage v. Cook Medical, Inc. et al., 1:14-cv -1875-RLY-TAB, was filed on behalf of a Gunther Tulip recipient. Its outcome could provide valuable insight into how juries might decide similar claims. Read More
