Investigation has been performed in our laboratory.In the visual examination of the cannula,it was determined that it is not straight but wavy in the sterile bag.After unpacking from the sterile bag,a damage was detected approximately 4cm before the end of the cannula.Also,complaint has been investigated by mcp tr.During production and packaging steps,the claimed products are checked visually,based on the basic operation procedures.The packaging design of the product is reviewed,so that the product cannot move within the package.Also,the samples have been tested by applying excessive force,and cannot be damaged similar to the complaint.Therefore,assembly and packaging failures can be eliminated.A review of the device history record was performed with no abnormality found.The pictures of the complaint have been reviewed,and it is realized that the sterile bag is not a product used in the production.Therefore,it could be possible that the claimed cannula can be used more than once.Based on this situation the complaint is not related to our production.A trend search has been performed which came to following results:no additional complaints were recorded.This is the failure was determined to be the first of its kind.Due to this information no systemic issue could be determined.Although the failure was confirmed,the most probable root cause could be determined as an user failure.Since the reported failure did not contribute to a death or serious injury no corrective action is needed.This data will be handled through a designated maquet trending process.If at trend occurs,it will be escalated to qa management for review and determination if further investigation is necessary.Due to this no further action will be completed at this time.
