The returned product sample consisted of one assembled catheter palindrome which presented signs of usage (blood residues).The possible causes were identified.No lot number was provided, therefore, it is not possible to perform a dhr review.None of the complaints have been confirmed manufacturing related issues.During visual inspection, a hole could be appreciated on the catheter just below the hub.During underwater test (functional test), bubbles were detected coming out below the hub.This defect has been confirmed.Based on the available information, the probable root cause can be considered most likely as misuse (leak could be caused due to over bending or excessive force).No additional action is required.It must be noted that in-process controls (such as personnel training, incoming quality acceptance testing for raw material, 100% in process visual inspection and visual acceptance sampling) are in place to prevent nonconforming product from leaving the manufacturing operations.Per procedure, manufacturing performs 100% pressure testing at the final stage of production, which would identify a leak in the catheter assembly.This complaint will be used for tracking and trending purposes.
