Concomitant medical devices: cook fusion omni-tome sphincterotome, fs-omni.Investigation evaluation: our evaluation of the product said to be involved determined that there was resistance and damage to the wire guide, but did not confirm the wire guide popping out of the duct.At approximately 12.5 cm, the distal tip of the wire guide was bent.A rough surface was felt from 151.4 cm to 162.7 cm, and kinks were seen at 155.4 cm and 159.6 cm.Slight discoloration was seen in and near the rough surface.Functional testing was conducted between the wire guide and sphincterotome.During functional testing the sphincterotome was advanced into an olympus (3.2 mm channel) endoscope which was placed in an upper gi position.The wire guide advanced out the distal tip of the sphincterotome with some resistance.The sphincterotome was removed from the endoscope and the wire guide had not popped out of the wire guide lumen.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.The instructions for use instruct the user to do the following: "prior to removing wire guide from holder, flush with 30 cc of sterile water." failure to flush the wire guide can result in damage to the wire guide.Prior to distribution, all acrobat 2 calibrated tip wire guides 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: 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.As reported to customer relations, "during the procedure, the guide wire was locked on the cook locking device and the wire kept popping out.Because of this, the physician was losing access [to the duct].The district manager was present for the case to help the physician and staff.The district manager was able to indicate to the physician a technique to use to remove the sphincterotome.The physician used a sweeping device (cook extraction balloon) to complete the procedure successfully.".
