Manufacturer Narrative

Block a2 (date of birth): the patient was born in 1932.Block h6 (device codes): problem code 2979 captures the reportable event of working channel sleeve protrusion.Block h10: visual assessment was performed after disinfection.As received, the black distal cap was pulled slightly off the catheter, likely a result of disinfection, handling, or shipping.Because of the condition of the device, the working channel sleeve protrusion amount could not be measured with the distal tip in neutral or when articulated.The distal tip was cut.The distal cap was removed.The catheter was cut open using the cutting fixture.The working channel sleeve was removed.Witness marks were noted on the pebax.The white and clear areas along bond a appear to show evidence of adhesion.These observations indicate that this device was manufactured correctly.However, the investigation of similar devices revealed a manufacturing issue related to bond b.Manufacturing process improvements have been implemented to address this issue.The complaint was consistent with the reported event of working channel sleeve protruding.Based on all gathered information, the probable cause selected for the working channel sleeve protrusion issue is manufacturing deficiency, which indicates that problems were traced to the manufacturing process.A dhr (device history record) review was performed, and did not identify evidence of deviations or non-conformances in the manufacturing processes that could contribute to the complaint.The dhr review confirms that the accepted device met all manufacturing specifications.
