A visual assessment was performed after disinfection.The catheter was kinked in several locations, beginning near the distal end.As received, the working channel sleeve protruded.The tips of the protruding sleeve were frayed.A functional assessment was performed and maximum protrusion was observed when the distal tip was articulated by turning the large knob in the clockwise direction.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 areas along bond a appear to show evidence of adhesion.The complaint was consistent with the reported event of working channel sleeve protruding.Based on the investigation results, the underlying cause of working channel sleeve protrusion is an insufficient bond, particularly the second heat cycle of the working channel sleeve bonding process [bond b]. therefore, the complaint investigation conclusion code selected for the working channel sleeve protrusion issue is manufacturing process design.An investigation is underway to address this issue.A dhr (device history record) review was performed and no deviation was found.
