Concomitant medical products: olympus sphincterotome, kd-v411m-0730.Investigation evaluation: our evaluation of the product said to be involved confirmed the report.The returned device is kinked which may have contributed to the resistance felt by the user.Kinks are approximately 1.9 cm, 3.3 cm, and 16.2 cm from the distal end.No damage to the wire guide coating was observed.A product-specific discrepancy that could have caused or contributed to this observation was not observed during our laboratory analysis.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.Instructions for use state the following: "flush endoscope accessory channel and/or lumen of device with sterile water, then insert wire guide floppy end first.Note: for best results, wire guide should be kept wet." prior to distribution, all acrobat® 2 calibrated tip wire guides are subjected to a visual inspection 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: 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.

During an endoscopic retrograde cholangiopancreatography (ercp), the physician used a cook acrobat 2 calibrated tip wire guide.The sphincterotome exchange was difficult because of resistance with the wire guide.Wire guide [access] was lost from the pancreatic duct due to this resistance.The following additional information was received on 05/16/2018: after wirsum [pancreatic duct] cannulation, the sphincterotome was being exchanged from a wire guide (locking elevator of duodenoscope v system), but a lot of resistance was encountered when performing the wire guide exchange from the sphincterotome.Because of this, the wire guide was pulled out from the wirsum.This caused a lot of extra time in the operating room (or).
