Cook Medical, a private Indiana-based medical device company, manufactured the Günther Tulip and Celect IVC filters. Post-market studies of the Celect filter — Cook's more widely implanted model — documented caval penetration rates far exceeding what was represented in premarket submissions. Caval penetration occurs when the filter's struts pierce through the vena cava wall, potentially injuring surrounding structures including the aorta, duodenum, spine, and ureters. Unlike filter fracture, caval penetration may not produce visible strut migration but still causes serious injury through mechanical pressure and perforation.

Cook MDL 2570 was established in the Southern District of Indiana before Judge Richard Young. The district is Cook's home jurisdiction, and the company has litigated aggressively. The first Cook MDL bellwether, Hill v. Cook Medical (2019), returned a $460,000 plaintiff verdict on Celect caval penetration claims. A subsequent bellwether in 2021 resulted in a defense verdict. Cook's litigation posture — no global settlement, continued defense at trial — means Cook plaintiffs face a more uncertain path to resolution than Bard plaintiffs.

If you had a Cook Celect or Günther Tulip filter implanted and experienced any complications, your case requires immediate attorney consultation. Because Cook has not established a settlement grid, individual case preparation — including early evidence preservation, imaging documentation, and MDL registration — is critical to maximizing your potential recovery.
