H10: as this malfunction is considered one event identified by the dealer; only one mdr report will be submitted for the reported quantity affected of thirteen for this event.Two lot numbers were provided (refv0321 and refr1982) with unclear information on the number of occurrences for each lot.Hence, d4(medical device lot number) has been updated as unknown.Additional unused lot samples of quantity 10 (five for refv0321 and five for refr1928) from the same lot/product catalog numbers were returned from the customer for evaluation and investigation of this event.H10: manufacturing review: the device history records have been reviewed and this lot met all release criteria.There was nothing found to indicate there was a manufacturing related cause for this event.Investigation summary: the physical device was not returned for evaluation but ten lot samples (five for refv0321 and five for refr1928) were returned for evaluation.One sample from refv0321 and one sample from refr1928 were opened and evaluated.The needles were loaded into the in-house driver and functionally tested in a chicken breast.The devices were tested 10 times on the 22mm setting, and 10 times on the 15mm settings, for a total of 20 tests.The devices fired and collected a sample each time with no issues.On dimensional observations, the devices were within the specifications for both the needle bent and notch thickness evaluation.Therefore, the investigation for the reported needle bent and difficult to remove for the lot sample is unconfirmed as the devices were working in fine condition.However, the investigation for the reported needle bent and difficult to remove for the original sample is kept as inconclusive as the original sample was not returned for evaluation.A definitive root cause for the alleged needle bent and difficult to remove could not be determined based upon the provided information.Labeling review: a review of product labeling documentation (e.G., procedural instructions, indications, warnings, precautions, cautions, possible complications, contraindications, nursing guide, and unit label) did not find any product labeling inadequacy.H11: section a through f - the information provided by bd represents all of the known information at this time.Despite good faith efforts to obtain additional information, the complainant / reporter was unable or unwilling to provide any further patient, product, or procedural details to bd.
