Intracranial Aneurysm Flow Diverter（OUT）

Flow diverter may have a manufacturing issue related to the tantalum length and/or tantalum attachment pattern, which may lead the device to be incompletely open or not properly apposed to the vessel wall, which may necessitate device recapture and withdrawal of the delivery system and microcatheter together. Insufficient apposition could lead to long-term health consequences.

Use of embolization device with diameters greater-than-or-equal-to 4mm may lead to incomplete wall apposition and/or braid deformation (fish-mouthing/braid narrowing/braid collapse) noted during procedure and post-procedure, typically noted at 6-12 month imaging follow-up, potentially can lead to thrombosis and/or serious adverse events. Higher risk in females less-than-or-equal-to 45 years of age

Intracranial aneurysm flow diverter device may be manufactured with an incorrect inner stent length and may not perform as intended.

Due to potential push wire fractures in the delivery system during use. The issue presents as a fracture in the spiral cut area of the Hypotube.

Embolization device delivery system may fracture at the distal section during device implantation. A weakened bond may result in unintended separation, where the distal portion of the device delivery system remains in the patient. If a Pipeline Flex embolization device has already been implanted successfully, there is no increased risk to patients due to this issue.

Delamination and detachment of the PTFE (polytetrafluoroethylene) coating material may lead to PTFE coating in the blood stream.

The firm is recalling Pipeline and Pipeline Flex Embolization Devices from U.S. since the devices were shipped with an EU version of the Instructions for Use.

Covidien Neurovascular has initiated the recall of several lots of Pipeline Embolization Device (PED) because the Instructions For Use (IFU) do not include the following contraindication: Patients in whom a pre-existing stent is in place in the parent artery at the target aneurysm location. Additionally, the designation of aspirin and clopidogrel was missing from the following contraindication "
