Medtronic announces voluntary recall of unused Valiant Navion Thoracic stent graft system

Written by | 24 Feb 2021 | Pharmacy

Medtronic plc has voluntarily issued a global recall of unused Medtronic Valiant Navion thoracic stent graft system and informed physicians to immediately cease use of the device until further notice.

In accordance with its commitment to patient safety – and in consultation with independent physicians – Medtronic initiated this action in response to information recently obtained from the Valiant Evo Global Clinical Trial indicating that three patients in the Valiant Evo Global Clinical Trial were observed to have stent fractures, two of which have confirmed type IIIb endoleaks. One patient death was reported.

Following these observations, an independent imaging laboratory reviewed all available images from patients enrolled in the Valiant Evo Global Clinical Trial. Upon further analysis of the images, seven (7) out of 87 patients were observed to have stent ring enlargement beyond the design specification. Those observations require further assessment to determine potential clinical importance. Medtronic is currently conducting a comprehensive technical root cause investigation, including further review of follow-up clinical trial imaging and commercial complaints and imaging.
