Cook Medical, Inc., IVC Filters
The Cook Medical IVC filter MDL was centralized in October 2014 to coordinate claims against inferior vena cava filter devices implanted to prevent pulmonary embolism, on allegations that the filters were prone to fracturing, migrating, tilting, or perforating the vena cava wall, and that retrieval — when even possible — could itself cause serious injury. With 6,501 actions still pending, this remains one of the larger active products-liability dockets by volume more than a decade into the litigation.
What drives duration and resolution risk here is a combination of bellwether-trial history and the absence, to date, of a comprehensive global settlement resolving the bulk of the inventory. The litigation has proceeded through a series of individual bellwether trials with mixed outcomes across different filter models and injury theories, which has helped establish the parameters courts and parties use to evaluate device-failure and warnings claims, but has not on its own produced the kind of docket-wide settlement architecture seen in some comparably sized mass torts. That leaves this docket in an unusually persistent active-litigation phase for its size and age.
A second structural driver of resolution risk is claim heterogeneity: because IVC filter complications range from asymptomatic fracture detected on imaging to major perforation or life-threatening retrieval complications, causation and damages proof — and therefore litigation strength — vary considerably across the pending population, which complicates any move toward a single, uniform settlement valuation framework applicable to the whole docket.
Criterica Intelligence tracks this pattern — large volume, mature bellwether record, no comprehensive settlement, high claim heterogeneity — as a distinct structural profile that behaves differently from either an early-stage mass tort or a post-settlement residual docket, and surfaces that structural read across every active MDL rather than relying on pending-action count alone.
It consolidates claims that Cook Medical's inferior vena cava filters, implanted to prevent blood clots from reaching the lungs, can fracture, migrate, tilt, or perforate the vena cava, and that retrieval of a failed filter can itself cause serious injury.
Bellwether trials are individual cases tried early to test how courts and juries evaluate the docket's core theories; this docket has run a series of them across different filter models with mixed outcomes, shaping how later claims are assessed.
No comprehensive global settlement has resolved the bulk of claims, and the wide range of complication severity across the claims population has made a single uniform resolution framework harder to reach than in some other device MDLs.
It proceeds toward an individual trial, informed by the substantial bellwether-trial record already developed in this docket on device-failure mechanisms and warnings claims.
