Lawsuit alleges Meridian IVC Filter defects

IVC filter 294x210 Lawsuit alleges Meridian IVC Filter defectsA Kansas woman has filed a lawsuit against C.R. Bard claiming her IVC filter was defective, resulting in injury, the Daily Hornet reports.

Cheri Ann W. was implanted with a Meridian retrievable inferior vena cava (IVC) filter made by C.R. Bard on July 8, 2014, at a hospital in Kansas with the intention of preventing pulmonary embolism, a deadly condition in which blood clots become lodged in the lungs.

Some IVC filters are meant to be permanent, while others are designed to be retrievable after the danger of blood clots has passed. Retrievable IVC filters are devices that resemble a spider, with a hook at its apex used for retrieval purposes. The device is designed to trap blood clots in the cage-like legs as they travel through the bloodstream, preventing them from moving into the heart or lungs. Cheri Ann’s complaint alleges her filter proved to be defective, and resulted in injury.

The FDA strongly recommends that retrievable IVC filters be removed between 29-54 days after implantation. If the filter remains in the body any longer, the risk increases of the device fracturing, tilting, migrating and/or perforating, the agency warns.

“These retrievable IVC filters, intended for short-term placement, are not always removed once a patient’s risk for PE subsides,” the lawsuit states. “Known long term risks associated with IVC filters include but are not limited to lower limb deep vein thrombosis (DVT), filter fracture, filter migration, filter embolization and IVC perforation.”

Makers of IVC filters, such as Bard, Argon Medical Devices, and Cook Medical, are facing more than 3,000 lawsuits filed by patients who claim they have been injured by the device, or by families of loved ones whose death was linked to the device’s alleged malfunction or failure. Bard alone is dealing with more than 1,700 lawsuits.
