Manufacturer Narrative

Concomitant medical products: cook zimmon pancreatic stent, spsof-5-5.Initial reporter occupation: non-healthcare professional.Investigation evaluation: our evaluation of the product said to be involved confirmed the report.Approximately 3.9 cm to 4.5 cm from the distal end, the wire guide covering accordioned.Approximately 4.6 cm to 4.7 cm from the distal end was a section of bare core wire.Approximately 4.7 cm to 5.3 cm from the distal end, the coating was stretched thin along the wire.The wire guide was bent approximately 4.1 cm to 10.9 cm and 218.8 cm to 234.5 cm from the distal end.Multiple rough surfaces are found along the length of the wire guide, more noticeably at 10.6 cm to 10.9 cm, 175.2 cm to 176.9 cm, and 213.6 cm to 214.8 cm from the distal end.Due to the condition of the returned device, it could not be determined if any sections of the coating were missing.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.If additional pressure is applied to the wire guide and/or accessory device(s) while moving the wire guide inside the accessory device(s), this could contribute to wire guide coating damage.Prior to distribution, all cook acrobat 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.

Event Description

During an endoscopic retrograde cholangiopancreatography (ercp), the physician used a cook acrobat¿ calibrated tip wire guide.The wire guide was advanced to the desired position and was ready to place the stent.The user released the stent and meanwhile withdrew the wire guide but there was slight resistance.The stent was placed in the desired position, the user tried to withdraw the wire guide, but found that they could not withdraw the whole wire guide.The user withdrew the wire guide along with the stent from the patient, found out [that] the surface of the wire guide peeled off, and was tangled with the stent.The user changed to another of the same wire guide and stent to complete the procedure.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.
