Device evaluated by manufacturer: the complaint device was received for analysis by the sfmd.The complaint sample received was already broached.Approximately half of the initial volume was left in the vial.A small dark particle was visible on the surface of the emulsion.The particle was isolated by filtering the emulsion through a filter.The isolated particle was microscopically evaluated and clearly proven to be a stopper-fragment, which has been poked out of the stopper when it was pierced.Stopper-coring is unfortunately an issue, which cannot be completely avoided, and which is not related to the quality of the product.A substance was found in the lubricant solution, however, it was determined to be a fragment of the device stopper, and not foreign matter.It has been comprehensibly evaluated that stopper coring during the application led to the occurrence of stopper fragmentation.
