Concomitant medical product: ultrathin endoscope, unknown make/model (2.8 mm channel).Investigation evaluation: our laboratory evaluation of the product said to be involved confirmed the report.The user did cut the device; however, due to the returned condition of the device we cannot confirm why the forceps cups could not close.The device was returned in three different pieces: the handle stem, the drive wire that was still attached to the handle spool, and the forceps cups attached to the catheter.A portion of the handle spool was missing during the return.The drive wire was returned outside of the handle, but still seated in the other half of the handle spool.A visual inspection was performed on the returned device.It appears that the user cut the catheter at 8.4 cm from the handle of the device.The length of the drive wire returned was measured at 165.6 cm from the end of the handle spool.The length of the catheter returned with the forceps housing still attached was measured at 153.7 cm.The device was assembled together by pieces.The drive wire was placed through the handle stem and through the catheter that is still attached to the forceps cups.The half of the handle spool was seated in the handle stem.The handle was then manipulated to see if the cups would open and close, but they would not.The device will be sent back to the supplier for further evaluation.Investigation conclusion: the product was returned to the approved supplier for evaluation and the investigation is on-going.Once additional information has been received a follow-up emdr report will be provided.

Event Description
|
During an endoscopic biopsy in the stomach, the physician used a cook captura mini biopsy forceps w/o spike.The cups could not be closed at the stomach during procedure.To perform first biopsy, the user opened the cups, however, it was impossible to manipulate when she attempted to close [the cups].She felt that she heard a snapping sound when the cups opened.To remove the device, the user cut the proximal side of the sheath, but the cups would not close, therefore the device and endoscope were removed from the patient's body together.Another device of the same lot number was used to complete the procedure without problems.There have been no adverse effects to the patient reported.

Investigation evaluation: our laboratory evaluation of the product said to be involved confirmed the report.The user did cut the device; however, due to the returned condition of the device we cannot confirm why the forceps cups could not close.The device was returned in three different pieces: the handle stem, the drive wire that was still attached to the handle spool and the forceps cups attached to the catheter.A portion of the handle spool was missing during the return.The drive wire was returned outside of the handle, but still seated in the other half of the handle spool.A visual inspection was performed on the returned device.It appears that the user cut the catheter at 8.4 cm from the handle of the device.The length of the drive wire returned was measured at 165.6 cm from the end of the handle spool.The length of the catheter returned with the forceps housing still attached was measured at 153.7 cm.The distal end of the drive wire that was returned appears to be near the solder joint location.It is possible that an incorrect solder joint contributed to the user's encounter of not being able to close the device since the cut the user made is in a different section than the solder joint.In an effort to perform a functional test, the device was reassembled together by pieces.The drive wire was placed through the handle stem and through the catheter that is still attached to the forceps cups.The half of the handle spool was seated in the handle stem.The handle was then manipulated to see if the cups would open and close, but they would not.The device was sent back to the supplier.The supplier provided the following evaluation: one device from the reported event was returned in a zip type bag with proof of decontamination.Evaluation of the device determined that the customer experienced issue of "would not close" could not be confirmed.The handle spool was dislodged from the handle stem and a portion of the catheter was removed by the end user and the device could not be functionally tested to determine if the cups opened and closed as intended.Root cause cannot be confirmed due to the condition of the device when received.Unable to determine whether the solder joint broke during assembly or during use.The device history record for the lot number said to be involved was reviewed.A discrepancy or anomaly was not observed with the product that was released for distribution.Investigation conclusion: the 'forceps cups would not close' issue experienced by the customer could not be confirmed.Although a root cause was not conclusively determined due to the condition of the device when received, the reported defect is consistent with a broken solder joint.The instructions for use state the following in regards to product inspection: "beginning at the handle and moving toward the cups, uncoil the forceps making sure not to stretch the cable.Open and close the cups to verify smooth handle operation and appropriate cup action.Become familiar with the amount of handle movement required to operate the cups.If any irregularities are noted, do not use.Note: exercising the handle while the forceps is coiled may result in damage to the performance characteristics of the forceps." prior to distribution, all captura mini biopsy forceps w/o spike are subjected to a visual inspection and functional test to ensure proper workability.A review of the device history record confirmed that the lot said to be involved met all manufacturing requirements prior to shipment.Corrective action: a review of the complaint history was conducted.The likelihood of occurrence is considered rare.Corrective action is not warranted at this time based on the quality engineering risk assessment.Quality assurance will continue to monitor for complaint trends and reassess the risk assessment results as post market feedback continues to become available.
