Device was de air balloon, crimped the valve on the delivery system, when the delivery system was deploying the valve every time the doctor would manually use the lock the knob would not allow alignment with the balloon.Tried trouble shooting with the vendor but it still wouldn't work.The balloon would not fully move inside the valve.Tried to free the balloon but the balloon wouldn't move further towards the valve.The valve was unable to be deployed.The whole system was decided to be removed with the valve, but the valve seemed to be pulled back into the sheath.A femoral cut down was done to remove the valve, a new device with a different lot number was used and worked fine.
