WEB Detachment Controller, REF: WDC-2, WDC, MV-WDC2. Component of WEB Aneurysm Embolization System.

Reason for recall

Detachment controller, of an aneurysm embolization system, has an out of specification tunnel opening dimension, which may prevent the implant device pusher from being fully inserted into the controller, which may result in the inability of the controller to properly detach the implant device, which could cause delays and excessive manipulation that may cause the implant to move and damage vessels
