Investigation summary: the manufacturing facility received the sample for evaluation.Upon examination a red/brown filament in fluid path was detected.The returned needle was examined under microscope without observing any damaged cannula point and well-deburred.Sample was tested (using different angles of penetration) using a lab vial with no difficulties and no particles from vials stopper fragmentation were found.A device history review was conducted and showed no abnormalities during the manufacturing process.Blunt fill needles are specially designed with unique 40° bevel to minimize coring effect and 1.5¿ long needle, to easily penetrate single and double septum barriers (rubber stoppers and iv bag septum¿s).When securing hub of needle to syringe, remove needle shield and ensure that needle punctures stopper at 90° to minimize risk of catching internal wall of vial stopper.Investigation conclusion: based on above results, available information, since review of dhr showed no indication or abnormalities of the alleged defect during needles manufacturing and taking into account the preventive measures and controls in place during the cannula manufacturing process, the coring effect (risk of catching internal wall of vial stopper) is unlikely to be caused by poor or insufficient de-burring process of the cannula.Nevertheless, the stopper conditions and the handling cannot be excluded to play a role which could have some potential implication in the coring effect issues.Needles blunt fill needle are specially designed with unique 40° bevel to minimize coring effect and 1.5¿ long, to easily penetrate single and double septum barriers (rubber stoppers and iv bag septum¿s).When secure hub of needle to syringe, remove needle shield and ensure that needle punctures stopper at 90° to minimize risk of catching internal wall of vial stopper.
