Medtronic’s Covidien unit has recalled (Class 1) its Palindrome and Mahurkar catheters due to a defect in the hub that connects both extension catheters. “There is a potential leaking condition within the hub of specific chronic dialysis catheters,” a [recall notice](https://www.fda.gov/medical-devices/medical-device-recalls/covidien-llc-medtronic-recalls-palindrome-and-mahurkar-hemodialysis-catheters-due-catheter-hub?utm%5Fmedium=email&utm%5Fsource=govdelivery) says. “This may be noticed when flushing one extension tube and the flow of fluid through the tip of the catheter returns unanticipated fluid through the adjacent extension tube. During treatment, this leak could result in mixing of the arterial and venous blood and lead to increased recirculation and poor dialysis, and the development of thrombi and emboli.” The implantable catheters are used in hemodialysis, apheresis (a technology that separates donated blood components to treat certain illnesses), and various infusions.
