Microvention WEB Detachment Controller Recall: Risk of Implant Misplacement
Microvention recalls WEB Detachment Controller (WDC-2) due to potential implant misplacement during aneurysm embolization. Affected units have specific serial numbers sold in China and Japan. Contact for remedy.
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
