The device history record (dhr) was reviewed and no deviations related to this condition were found.There are no non conformance reports (ncr)¿s related to the reported issue and lot.The product sample was returned for investigation; a palindrome catheter, clip and syringe were received inside a generic plastic that presented signs of use (remains of blood).A visual inspection was performed and pinholes were found on the arterial extension.In order to confirm the condition reported functional test was required.The returned sample was submitted to underwater testing and bubbles were detected coming from pinholes of the extension of catheter, from the lumen which corresponds to the arterial extension.The lumen related to the venous extension did not show bubbles during the test.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.Additionally, manufacturing performs a 100% visual inspection on catheter extensions and a 100% high pressure (leak) test.The product specification was reviewed in order to identify the possible root causes for the leaking.The most probable root cause could occur during use caused due to the use of sharp objects, repeated clamping or other similar damage as described in the instructions for use.Should the sample be returned in the future, this complaint will be re-opened for further investigation.It must be noted that in-process controls such as personnel training, incoming quality acceptance testing for raw material, in process visual inspection and visual acceptance sampling are in place to prevent nonconforming product from leaving the manufacturing operations.Manufacturing performs a 100% leak test and a 100% visual inspection during production, which would identify this issue in the catheter assembly.This complaint will be used for tracking and trending purposes.
