Submit date: 03/04/2017.As no lot number was identified, a manufacturing device history record (dhr) review or product/process changes review for the involved lot number could not be performed.However, all dhrs are reviewed for accuracy prior to product release.The product sample was returned to the manufacturing site for review, it consisted in a palindrome catheter.The sample came inside a plastic bag that is not the original of the product.During visual inspection, the cuff of the catheter presents signs of use (remains of blood).In order to confirm the defect reported, a new stylet were passed through both extensions; as result the stylet passed easily through the lumens.As part of the evaluation, the sample was flushed and did not present any problem in the extension; the water passed easily through the lumens.Therefore the defect was not confirmed.Based to the evaluation of the sample the catheter did not reveal any problem related to the reported condition.It is possible considering the device dueling time, that there is a patient related condition (catheter placement in the vessel or internal kink) that may explain the reported condition.Based on the available information, it can be concluded that product was manufactured according to specifications and the most probable root cause can be considered as a patient related condition / catheter placement.It must be noted that in-process controls (such as personnel training, incoming quality acceptance testing for raw material, 100% visual inspection, and visual acceptance sampling are performed in the plant) are in place to prevent nonconforming product from leaving the manufacturing operations.No additional actions are required.This complaint will be used for tracking and trending purposes.
