About IVC Filters
Retrievable inferior vena cava (IVC) filters are small devices resembling spiders that are implanted into the vena cava to filter, or catch, blood clots that have broken free, preventing them from reaching the lungs and causing a pulmonary embolism.
IVC filters are designed to be implanted in the body for a limited amount of time and removed when the danger of pulmonary embolism has passed; however, concern has grown that too many IVC filters are not being removed in a timely manner and instead allowed to remain in the body and expose patients to unnecessary risk.
Besides Cook, other IVC filter manufacturers, including C.R. Bard, are the subject of a rising number of product liability lawsuits alleging serious harm and death caused by these devices.
