The complained catheter has been returned for investigation.No indications for a material deficiency (like air bubbles, particles) could be detected by naked eye and under the microscope.A simulated leakage test of the complained device could confirm the leakage as described in the complaint.A dhr review could not identify any non-confomities or deviations relevant to the reported issue.A 100 % leakage test is performed during production.A systematic weakness in the production process is considered as unlikely due to the very low complaint rate (<0,01 % for all types of picco catheter).No similar complaints have been received for this batch.Considering the complaint investigation results and the appearance of the crack (linear shaped propagation, originating from luer lock connection) it is seen most probably that excessive force (potentially by overriding the connection between pressure transducer and catheter) in combination with alcoholic disinfectant has been applied.According to the customer no alcoholic disinfectant has been used.It cannot be exluded that any unknown tool has been used to tighten the connection.Upon the event occurrence the device was involved, but not used on a patient.The issue has been detected prior to puncture, when the catheter was inspected and connected to the pressure transducer.The evaluation results did not indicate that the device failed to meet its specification.The ifu states: ¿the luer-lock connection is to be tightened manually.The use of any tools or excessive force may damage the connection component and lead to leakiness.¿ and "usage of organic solvents for cleaning and disinfection may damage the catheter and lead to leakiness.¿ the issue will be further monitored on the market in order to indentify any trend.
