Stockert 3T Heater-Cooler SystemDevice Can Lead to Bacterial Infection

Stockert 3T Heater-Cooler Device Lawsuit

If you recently had open-heart surgery, you may have contracted an infection from the medical device that keeps your body warm during a surgical procedure and could qualify for a heater-cooler device lawsuit.

The Stockert 3T Heater-Cooler System is a medical device that keeps your body temperature regulated during cardiac surgeries. The water tanks in the device can become contaminated with Mycobacterium Chimaera either at the manufacturing plant where the device is developed or the hospital where the surgery occurs. The bacterium can cause Non-Tuberculous Mycobacterium (NTM) in patients with an open wound or poor immune systems. Numerous heater-cooler device lawsuits are currently being filed on behalf of those who contracted the potentially deadly infection.


What is the Stockert 3T Heater-Cooler System?

The Stockert 3T Heater-Cooler System is a medical device that regulates your body temperature during cardiac surgeries. Essential for life-saving surgeries, the device keeps circulating blood and organs at a constant temperature by heating and cooling the body during open-heart surgery.

In simple terms, the heater-cooler units keep your body at a constant temperature by providing temperature-controlled water to heat exchangers through closed circuits thus warming your body. The water never comes in contact with your body, but the three water tanks are potentially creating Mycobacterium Chimaera, a potentially deadly, but slow growing, bacterium to those with open wounds and low immune systems. Vapors exiting the device’s exhaust vent are polluting the air with bacterium could then enter the open wound during surgery.

Unfortunately, the source of the contamination can occur in two places – at the manufacturing plant and/or the hospital. The two potential contamination issues increase the risk of infection in patients.

The bacterium, commonly found in soil or water, is typically not harmful, but is slow growing and can cause infections in those undergoing surgery or suffering from a suppressed immune system.

Becoming available to the market in 2006, the device has been used in over 250,000 heart bypass surgeries throughout the United States. 60% of those surgeries used the Stockert 3T Heater-Cooler System.

The FDA has said that similar devices may also have the same design flaw as the Stockert 3T Heater-Cooler system that causes bacterium infections. The flaw relates to contamination during the manufacturing period.


Side Effects of the Stockert 3T Heater-Cooler System

The device has been found to cause potentially deadly side-effects.

  • Non-Tuberculous Mycobacterium (NTM) infections caused by the Mycobacterium Chimaera bacterium can be deadly to those recovering from surgery situations where the immune system is not as strong. The bacterium enters the air through the contaminated medical device and enters the open wound. Detection of the infection often doesn’t occur until months or even years after the surgery, and as a result, can be difficult to discover. Side effects can include:
    • Night Sweats
    • Muscle aches
    • Weight loss
    • Fatigue
    • Unexplained fever

If you believe you may be suffering from adverse side effects due to a Stockert 3T Heater-Cooler System used during your open-heart surgery, please contact a medical professional right away.


Stockert 3T Heater-Cooler Device Lawsuit Updates

May 2014 – Greenville Memorial, a South Carolina hospital asked state and federal investigators to investigate the link between the medical device and patients who developed an infection.

August 2014 – The FDA became aware of an alert issued by LivaNova PLC, the manufacturer of the device, about the device’s potential to cause patient infection after a surgical procedure and begins their own investigation.

December 29, 2015 – The FDA issued a warning to LivaNova PLC after inspections conducted at two manufacturing plants revealed significant issues and an increased possibility of contaminated heater cooler devices. The manufacturer recalled the instructions for use but did not recall the device itself.

June 2016 – The FDA released the first safety communication warning associated with the Stockert 3T Heater-Cooler System. The warning directly notified both patients and surgeons of infections linked to the devices.

October 2016 – The FDA updated its safety warnings to include the risk of developing a bacterial infection, known as Mycobacterium Chimaera (M. chimaera). Steps to prevent a bacterial chimaera infection, for both surgeons and patients, from occurring were also included in the warning.


Heater-Cooler Device Lawsuit

Since 2010, about 79 cases of infection, including 12 deaths, caused by the use of the Stockert 3T Heater-Cooler System have been reported to the U.S. Food & Drug Administration. As a result, class action lawsuits are being filed across the country.

If you believe you contracted a NTM infection during an open-heart surgery, please contact a knowledgeable attorney. You may qualify for a heater-cooler device lawsuit.
