The device history record was reviewed and indicated that the product was release accomplishing all quality standards.A palindrome catheter was received inside a generic plastic bag.The catheter presented signs of use (rests of blood).In order to confirm the defect reported, sample was submitted to underwater test and bubbles were detected.The lumen related to the arterial extension did not show bubbles during the test.A pinhole was found on the venous extension.Based on the available information and the result of the dhr review that showed no deviations, it can be concluded that the product was manufactured according to specifications and the device functioned as intended for the reported amount of time.The most probable root cause can be considered as misuse; this defect was more likely damaged during use caused due to the improper use of sharp objects, repeated clamping or other similar damage.The evidence provided is enough to discard the manufacturing process as a potential cause.A qseas evaluation took place to assess this exceeded risk threshold, no further investigation activities or corrective actions were required and a hhe evaluation was opened.It must be noted that in-process controls (such as personnel training, incoming quality acceptance testing for raw material, 100% in process visual inspection, leak testing and visual acceptance sampling) are in place to prevent nonconforming product from leaving the manufacturing operations.As per procedure manufacturing performs 100% leak testing and a 100% visual inspection during the final stage of production, which would identify this issue in the catheter assembly.No additional actions are required.This complaint will be used for tracking and trending purposes.
