According to the Philadelphia Inquirer, health care supplier Covidien has been sued for wrongful death by the estate of a man who died after being treated with tainted heparin. Heparin is the blood thinner that was recalled late last year after it was discovered that an ingredient used in the drug had been contaminated by an OTC dietary supplement wrongly added by a manufacturing plant in Changzou, China. The Missouri victim had allegedly never been contacted with a recall notice or warnings about possible problems with the medication.  Suppliers other than Covidien had already begun their recall process weeks before the 67-year-old man died, ironically on the same day that Covidien began recalling heparin. The Philadelphia Inquirer reports that the plaintiff's attorneys warn that tainted heparin remains in circulation and that other deaths could follow.
