An incomplete device was returned with damage to the delivery system noted upon return, which was previously not reported.The user indicated there were no issues with the clip prior to use or any issues during the delivery/anastomosis process.Given the condition of the returned device, a complete investigation was not possible and a conclusion regarding the cause of the event cannot be determined.

The device's clip was used to create the proximal anastomosis of a bypass graft during open cardiac bypass surgery.Approximately two hours after creating the anastomosis and prior to completion of the surgery, the graft dislodged from the aorta.While using a pump-oxygenator, the surgeon removed the clip from the graft and sutured the graft to another location.The procedure was completed.
