Event Description

During an endoscopic retrograde cholangiopancreatography (ercp) procedure, the physician used a cook fusion omni-tome.It was initially reported that the physician stated that he had to take a needle knife doing the ercp procedure , and when he wanted to take the fs-omni back, the cutting wire was broken.Two photos of the device were provided which show the cutting wire broken.There was no reportable information at this time.Our evaluation of the returned device on 3/16/2022 determined that the cutting wire securing component (anchor) separates from catheter (w/ detachment) resulting in tip will not bow.According to the initial reporter, a section of the device did not remain inside the patient¿s body, but a portion of the cutting wire measuring approximately 3.0mm in length and 0.5mm in diameter is missing and was not included in the return of the device.No further information was provided by the initial reporter, and it was stated that the patient did not require any additional procedures and the patient did not experience any adverse effects due to this occurrence.

Manufacturer Narrative

Pma/510(k) # k172288.Investigation evaluation: the product said to be involved was returned in an open pouch from the lot number provided in the report.The label matches the product returned.Photos were also provided.The pictures provided shows the cutting wire no longer attached at the tip, it is unclear if this is due to cutting wire breakage or cutting wire separation.The lot number was not provided.Our laboratory evaluation of the product said to be involved determined the cutting wire securing component located near the distal end of the sphincterotome has disconnected from the catheter.However, the cutting wire is intact and remains securely attached to the sphincterotome at the proximal end.A section of the cutting wire securing component has broken and detached from the device.The broken section is estimated to be 3.0mm in length and 0.5mm in diameter.The broken section was not included in the return.The cutting wire exhibits slight evidence of a cautery application (blackening of the cutting wire was noted).A product discrepancy or anomaly that could have contributed to this reported occurrence was not observed.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: a definitive cause for this observation could not be determined because the actual use conditions could not be duplicated in the laboratory setting.Due to a variety of clinical conditions such as patient anatomy, endoscope position or progression of disease state, we could not reproduce the actual conditions of product usage during our laboratory analysis.This limits our ability to conclusively determine a cause.Separation of the cutting wire securing component and the catheter can occur if the tip of the sphincterotome is over flexed.The instructions for use caution the user: "do not over flex or bow tip beyond 90 degrees, as this may damage or cause cutting wire to break." other factors that can contribute to separation of the cutting wire securing component and the catheter include manipulating the handle with the catheter in a coiled position or with the precurved stylet inside the cannulating tip.The instructions for use advise the user: "upon removing device from package, uncoil and straighten sphincterotome.Carefully remove precurved stylet from cannulating tip." the instructions for use contain the following comment: "note: do not exercise handle while device is coiled or precurved stylet is in place, as this may cause damage to sphincterotome and render it inoperable." prior to distribution, all fusion omni-tomes are subjected to a visual inspection and functional test to ensure device integrity.The functional test includes bowing the sphincterotome to ensure the distal end responds to handle manipulation.A review of the device history record confirmed that the lot said to be involved met all manufacturing requirements prior to shipment.Corrective action: 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.
