Dhr review shows the product cat.(b)(4), lot # 7135264 were packed on (b)(6) 2017.The packed quantity was (b)(6).After reviewing the batch record, no abnormality found in the process.The inspection process and outgoing process both met the requirements.An actual sample and two representative samples were received for the purpose of our investigation.The investigators were able to observe the reported failure mode in the sample provided.The catheter was noted to have a sloped break, additionally a cross-section of the tubing revealed an oval shape, as opposed to, the round cross-section of an unaffected representative samples.Used microscope to check, the catheter was oval.These two observations suggest the failure of this device is unrelated to the manufacturing process, and that the most probable root cause for this failure mode is that the catheter was broken or cut with an edged tool.
