H6: investigation summary one sample in open packaging was received by our quality team for evaluation.The sample was subjected to visual inspection.Under 20x magnification, small lumps of transparent, gel-like substance were observed on the surface of the catheter tubing.However, the lubricant appearance was found to be acceptable.Tip spear damage was also observed on the catheter tip.A device history record review found no non-conformances associated with this issue during production of this batch.Based on the returned samples, small lumps of transparent, gel-like substances observed on the catheter tubing were most likely to be excessive lubricant that aggregated and formed small lumps on the catheter surface.Given the gel-like nature of the lube, it was possible for the lubricant to flow to different locations on the catheter during transportation or storage.The lubricant appearance on the returned samples was found to be acceptable.For the unreported tip spear damage that was observed on the catheter tip, there is an 100% inline vision inspection system at the main assembly line to detect and fail samples with tip spear.This is most likely caused by the user handling during needle cover removal or during insertion.The actual root cause could not be established as the sample was returned in open packaging.
