A multi-million dollar lawsuit is alleging that a medical device that overheated during routine cardiac surgery caused a Washington man's heart to cook from the inside, reports the Everett Daily Herald. According to the lawsuit, faulty computer code caused a catheter used to monitor blood flow during bypass surgery to reach 500 degrees and melt. The man's heart was destroyed, according to the Everett Daily Herald. He had to receive a heart transplant as a result of the burns, and has since developed cancer directly attributable to the many anti-rejection drugs he now takes. The catheter manufacturer has accepted responsibility for the man's injury, but contends that the hospital should share the blame. The medical device has since been recalled.
