Manufacturer Narrative

Livanova received a report stating of outllet tubing disconnection during a procedure.No patient/user affected.Unit is not available.According to the technical documentation of the circuit, the involved connection is assembled by the customer.This was confirmed also through the event description details, livanova learned that the line involved was connected by the customer to the outlet of a quadrox oxy and tie banded.Indeed, the involved connection was not performed during the livanova manufacturing.The dhr review highlighted that the lot whose claimed product belong to was released as conform according to specifications.The same customer reported another similar event on the same lot 14 days later.The reported disconnection can be due to a deviation in the chemical characteristics of the tubing (supplied by an external supplier) or to an improper connection made by the customer.Investigation of similar previous events did not identify any tubing significant measurable deviation nor any other specific reoccurrence that could suggest a specific root cause (no specific reoccurrence in the disconnection points, blood pressures, connection types, connections made by livanova operators or by customers).However, it could be not ruled out that untestable manufacturing and chemical deviations may have contributed to disconnection.The risk is in the acceptable region.No action is deemed necessary.Livanova will keep monitoring the market.
