The concerned product has not been returned as it was discarded by the hospital.Therefore it is not possible to determine if the used product had any malfunction or any deviation from the specification, that contributed to the event.A retain sample of the same batch has been investigated but no deviation to specification could be detected during visual and functional testing of the described failure.A dhr check could not identify any deviations or abnormalities relevant to the reported issue.An investigation has been performed on the basis of the provided pictures: the hospital had removed the red cup of the thermistor connector and traces of blood could be detected in the thermistor plug.A systemic root cause as a deficiency of design, production or material is considered as unlikely due to the very low complaint rate (< 0,01 %, considering all types of picco catheters).No similar complaints have been received since 2017.Considering the provided information and product experience, the most probable root cause is seen in a single production process problem during molding of the channel separation.This evaluation indicates that the device failed to meet its specification, however the involved product has not been returned.Upon the event occurrence the device was involved and used on a patient for advanced hemodynamic monitoring.100 % leak tests are performed during production.The issue will be further monitored on the market in order to identify early trends.
