All the retained samples tested were confirmed full compliance with product specifications.The customer sample was investigated and confirmed that the debris observed on the defective unit of sol-m blunt fill needle 18g 1 1/2" (ref# 110022, lot# 02503011) originated from the needle cap.Visual inspection under an optical microscope showed that the debris was located only on the external surface of the cannula, with no traces inside the lumen.The fragments exhibited a reddish color and a plastic appearance.Ftir analysis identified the debris as polypropylene.A spectral comparison with the needle cap confirmed that the material of the fragments matched the cap.This finding is further supported by visible marks inside the needle cap, consistent with the generation of the debris.Based on all available evidence, the debris did not originate from the cannula itself nor from the manufacturing process.The most likely root cause is that the fragment was generated during removal of the needle from the cap, causing the cannula to scrape against the inner cap surface.It is recommended that the customer remove the cap in an axial direction without tilting it, to prevent the cannula from scraping against the walls of the cap and generating debris.Our evaluation of the risk, which follows guidance from iso 14971, indicates that the overall risk for the reported failure is low.This evaluation is based on our track and trend analysis and risk management files which are evaluated and updated constantly based on post market surveillance.As part of our continued commitment to our customers, sol millennium will continue to monitor the complaints trend for the reported failure mode and take any corrective action based on our procedures, if a significant pattern emerges.
