Repeated medical studies show that after one month, filters can embed, tilt, migrate, fracture, etc. Ironically, failing filters themselves can cause clots by disrupting blood flow. A March 2016 article in the Journal of American Cardiology Cardiovascular Interventions, Inferior Vena Cava Thrombosis, warns that “thrombosis of the inferior vena cava (IVC) is an under-recognized entity that is associated with significant short- and long-term morbidity and mortality.”
These filters are designed to treat patients with an acute condition causing clots. We are filing suits for victims who have had surgical removal of a failed filter or have a filter which can’t be removed that poses an acute hazard. Bard, Cordis and Cook are the major players, with smaller market share being held by ALN, Rex Medical, Braun, Birds Nest and Crux.
Liability continues to strengthen as discovery proceeds. When defendants redesigned permanent filters into retrievable ones, weakened structural designs resulted. If filters are retrieved within a month they are usually safe, something device companies never explained.However, the “temporary” filters were left indefinitely.
Bard has recently indicated they may consider settling these matters.
