Supplemental report is being submitted due to the completion of the investigation on 13-aug-2026._____________________________________________
investigation - evaluation
device evaluation:
the blb-024115 device of lot c2211496 was returned for evaluation.With the information provided, a physical examination and document-based investigation was conducted.The devices related to this occurrence underwent a laboratory evaluation on the 06th july 2026.The lab evaluation notes and lab attendance can be viewed in the ¿examination of returned device¿ section.On evaluation of the devices the following observations were made:
visual inspection:
spool device and coiled wire returned separately.Device examined and no issues observed.Wire examined and no issues observed.Jaws returned open.Functional inspection:
wire loaded onto the device.Jaws open and close as expected.The reported failure was not observed.Manufacturing records:
prior to distribution all devices are subjected to a visual inspection and functional inspection to ensure device integrity.A review of the manufacturing records of lot number did not reveal any discrepancies that could have contributed to this complaint issue.Review historical data:
the review of relevant manufacturing records of lot number confirms the failure mode has not previously occurred for this work order.Instructions for use and/label review:
it should be noted that the instructions for use (ifu0034) states the following:
¿after the handle is attached, ensure the operation of the biopsy cups before surgical introduction.Biopsy cups default to the closed position.To open the biopsy cups pull the finger spool towards the thumb ring.To close, push the finger spool forward.Note: biopsy cups need to be in the closed position before surgical introduction.¿
"visually inspect the product to ensure no damage is occurred.If the package is opened or damaged when received, do not use.If abnormality is detected that would prohibit working condition, do not use".There is no evidence to suggest that the customer did not follow the instructions for use.Image review:
an image was not returned for evaluation.Root cause analysis:
a definitive root cause could not be determined based on the investigation.The returned device functioned as intended during laboratory evaluation, and the reported failure could not be replicated.According to the customer, the biopsy cups were stiff and opened intermittently during use before the device was replaced.However, during evaluation, the biopsy cups opened and closed as expected.Based on the available information, a possible root cause may be attributed to a temporary increase in friction within the device during clinical use, which may have prevented the biopsy cups from fully closing.The exact cause of the increased friction could not be determined.Confirmation of complaint:
complaint is confirmed based on customer and/or rep testimony.Corrective action/correction:
complaints of this nature will continue to be monitored for similar events.Summary of investigation:
according to the customer, the device would not close.Confirmed quantity of 1 device, confirmed used.According to the initial reporter, no adverse effects on patient have been reported.A possible root cause may be attributed to a temporary increase in friction within the device during clinical use, which may have prevented the biopsy cups from fully closing.
