The U.S. FDA posted notice of a class I recall for two hemodialysis catheters made by Covidien Inc., the Palindrome and Mahurkar catheters, due to a catheter hub defect that could lead to mixing of venous and arterial blood. No deaths and only one injury have been reported in connection with the defect, but the recall affects more than 1 million devices that went into distribution starting in June 2017, one of the numerically larger recalls in recent years.
