The concerned guidewires have not been provided as they were discarded by the hospital; no pictures have been provided.Therefore it is not possible to determine if the used guidewire had any malfunction or any deviation from specification that could have contributed to the event.A retain sample from the same batch has been investigated but no deficiency could be detected during visual and functional testing.A dhr review did not reveal any non-conformities relevant to the reported issue; no similar complaints have been reported for this batch.Information provided by the customer explained that there was no initial malfunction of the guidewire as the guidewire and catheter could be inserted without any problems.The complaint rate of similar complaints considering all kind of picco catheters is low (<0,01 %).The picco technology is used for advanced hemodynamic monitoring.Based on the circumstances, investigation results and experience, the most probable root cause is seen in a handling error by the user by applying excessive force during retraction, as the ifu indicates: ¿if resistance is encountered when removing the guide wire, the guide wire could be kinked about tip of catheter within vessel.In this case withdraw the catheter by 2 to 3 cm and try again to remove the guide wire.Use of excessive force may tear off the guide wire.Therefore, guide wire and catheter are to be removed simultaneously.¿ the patient had a weight of more than 150 kg, it cannot be excluded that this factor has contributed to the event.Contraindications are stated in the ifu that a picco catheter should only be used if the expected results are reasonable in comparison to the risks.Device has not been returned from the hospital as it was discarded.
