Several lawsuits filed against the makers of the Stockert 3-T Heater-Cooler System allege the device put patients at risk for infection. The claims further allege that the manufacturers were aware of the risks but failed to warn the medical community or consumers. According to claims, LiveNova and WellSpan Health knew the device allowed for the transmission of bacteria during surgical procedures, especially open-chest cardiothoracic surgeries. The first lawsuit filed in June 2016 claimed that the plaintiff had developed a mycobacterial infection during his open heart surgery procedure that utilized the Stockert 3-T system. Later that month, a similar complaint was filed by the family of a 62-year-old man who died after the system was used during his surgical procedure at York Hospital in Pennsylvania, which is owned by WellSpan Health. The following month, a South Carolina man filed a product liability lawsuit against LivaNova when he developed an NTM infection after his heart valve replacement and cardiac bypass grafting surgery. He claimed he was initially fine, but went on to develop weakness, a fever, and eventually pneumonia during his recovery from the procedure.
