September 21, 2021 — Medtronic is recalling its Pipeline Flex Embolization Device and Pipeline Flex Embolization Device with Shield Technology, which are transcatheter devices used to seal brain aneurysms. The company said there is a risk of the delivery system’s wire and tubes fracturing and breaking off when the system is being used to place, retrieve, or move the stent inside a patient.
The FDA has identified this as a Class I recall, the most serious type of recall. Use of these devices may cause serious injuries or death.
Fractured pieces could be left inside the patient’s brain bloodstream. It is also possible that attempts to retrieve the fractured pieces may make the patient’s condition worse. The fragments can also cause other serious adverse health consequences such as continued blockage of blood vessels, stroke, and death.
There have been 59 reported device malfunctions, 10 serious injuries, and two deaths related to this recall.
The recalled includes 8,825 devices in the United States that were distribution between April 18, 2019 to Aug. 13, 2020.
Medtronic is the parent company of Micro Therapeutics Inc., ev3 Neurovascular, which makes the devices.
A recall letter was sent to all customers July 13, 2021, requesting them to:
• Stop use of any impacted product.
• All unused impacted products should be immediately quarantined.
