Covidien has announced that it has notified customers of a voluntary recall to address an issue with certain lots of its Pipeline embolisation device and Alligator retrieval device where the polytetrafluoroethylene (PTFE) coating applied to the delivery wire could delaminate and detach from the devices.
PTFE coating is used to reduce friction between devices and ease navigation through the vasculature. Delamination of the PTFE coating could potentially lead to embolic occlusion in the cerebral vasculature with the risk of stroke and/or death.
Covidien learned of this issue through internal product testing. The company has not received any reports of patient injuries to date related to this issue.
The Pipeline embolisation device is indicated for the endovascular treatment of adults (22 years of age and older) with large or giant wide”necked intracranial aneurysms in the internal carotid artery from the petrous to the superior hypophyseal segments. The Alligator retrieval device is intended for use in the peripheral and neuro”vasculature for foreign body retrieval.
A total of 32 Pipeline embolisation devices and 621 Alligator retrieval devices are affected by this recall. The products were manufactured and distributed from May 2013 to March 2014. This issue involves both the Pipeline embolisation device sold in the USA, Australia, France, Germany and United Kingdom, and the Alligator retrieval device, which is sold in the USA, Australia, Canada, Europe and Latin America.
Covidien alerted customers to the recall by letter on April 1, 2014, and is arranging for replacement of the recalled products. The US Food and Drug Administration (FDA) and other regulatory bodies also have been notified.
