Event or Problem Description
During an endoscopic retrograde cholangiopancreatography to remove bile duct stones, the physician used a cook memory hard wire basket.It was reported that the basket could not be retracted into the sheath.Despite repeated attempts to push and pull, the sheath became deformed.Subsequently, the basket was removed and a stone retrieval balloon was used to extract the stones.A section of the device did not remain inside the patient¿s body.The patient did not require any additional procedures due to this occurrence.According to the initial reporter, the patient did not experience any adverse effects due to this occurrence.
Additional Manufacturer Narrative
Investigation evaluation: the product said to be involved was returned in a white plastic bag.Provided with the return was an open pouch from the lot number provided in the report.The label matches the product returned.Our laboratory evaluation of the product said to be involved confirmed the report.The device returned with the basket fully advanced.Buckling was observed in the clear catheter distal to the white shrink tubing.While the device was relaxed on the tabletop, the basket was not able to retract.The basket would retract to the point before it would begin to fold into the catheter and then reach resistance which exacerbated the catheter buckling and prevented retraction.When the device was fully straightened retraction became possible with minor friction as the drive wire passed through the buckled portion of the catheter.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: our evaluation of the returned device confirmed the report.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.Prior to distribution, all memory hard wire baskets are subjected to a visual inspection and functional testing to ensure device integrity.A review of the device history record confirmed that the lot said to be involved met all manufacturing requirements prior to shipment.Corrective action: based on the quality engineering risk assessment no corrective action is warranted at this time.A review of the complaint history was conducted.Based on this review, the likelihood of this type of report is rare.Quality assurance will continue to monitor for complaint trends.
