Livanova received a report stating that air was drawn into the vanguard device during priming.No patient or user was affected.A confirming video was provided.During the test, the outlet side of the heat exchanger was clamped, priming was carried out from the inlet side of the heat exchanger, and the heat exchanger was filled with water.The outlet side was clamped, the inlet side was released, and the water level in the heat exchanger was checked with a head pressure.From the air filter to the outlet of the outflow tract, a 100 cm, 50 cm, 20 cm height was used to check.At jms the issue was confirmed, in particular the priming solution flowed out from the inlet port and the water level inside the device was decreased.No device service history review was performed since no lot number was provided.Based on the facts above, it cannot be ruled out that the most likely root cause of the reported issue are: damaged umbrella valve.Accidental misplacement of the umbrella valve.No specific action was currently deemed necessary, livanova maintains and document periodic customer events monitoring process in order to evaluate actions for products improvement.H3 other text : investigation performed by assembler.

The involved bcd vanguard, labeled with shop order (b)(4) was received at livanova facility for investigation.From visual inspection, bubbles were observed around the umbrella valve at the top of device.The device has been returned with the white protective cap correctly assembled from the umbrella valve on top area.After the test the umbrella valve has been visually inspected and no deformations nor damages have been found on this component.Investigation result confirmed amptying of device from inlet connector and water dripping from top area.Livanova believes the most likely root cause of the reported issue is a potential mix-up in production line between good umbrella valve with a pinched or not perfectly seated umbrella valve in its dedicated housing.The residual risk is still acceptable.Livanova will maintain to monitoring the market.
