Evaluation summary: a device history record (dhr) review revealed no discrepancies that may have contributed to a complaint of this failure mode.All quality assurance testing performed during manufacturing was acceptable.In addition, all dhrs are reviewed for accuracy prior to product release.Two photos were provided by the customer.Visual evaluation of these photos was performed.The pictures showed part of the extensions of catheter over a surface with a paper sheet.The venous extension has no clamp, and an arrow on the sheet points out the venous extension.In these pictures, the extension has white stains that could be a crack.One palindrome catheter was received for analysis and investigation.Visual inspection revealed that the catheter presented signs of use.Functional testing was required to confirm the reported condition.The sample was submitted to underwater testing and bubbles were detected coming out of 2 pinholes on the venous extension.The arterial extension did not show bubbles during the test.The manufacturing process was reviewed to determine potential points of damage to the extension.The result was that the operations that are applied to the extension are lig ht and the handling of the pieces is manually done, there is no use of sharp objects or other instrument that could generate the hole found during visual inspection.100% of the devices are inspected for leaks or cuts in the extensions per procedure.There are no elements encountered during the manufacturing process that could origin the condition reported.The instructions for use (ifu) state the customer must perform a visual inspection before using the device.It states to exercise caution when using sharp instruments near the catheter because catheter tubing can tear when subjected to excessive force or rough edges.The reported condition has been confirmed.Based on the testing evaluation, the most probable root cause can be considered damaged during use.The evidence provided is enough to discard the manufacturing process as a potential cause.No trends or trigger were identified, no harm was reported for this complaint and this is not a manufacturing/supplier related event.No further actions are deemed necessary at this time.This complaint will be used for tracking and trending purposes.If information is provided in the future, a supplemental report will be issued.
