Flexible endoscopes are characterized by their design, which includes multiple internal channels. This feature is particularly important because each channel may be used for different functions, such as delivering air, water, or suction. The presence of these channels demands thorough cleaning and reprocessing to ensure that all potential contaminants are effectively removed. This is a significant consideration in the reprocessing cycle, as the complexity of these endoscopes increases the risk of biofilm formation and infection transmission if proper cleaning protocols are not followed.

The other options do not accurately represent the fundamental characteristics of flexible endoscopes. For instance, they do not require minimal cleaning due to their intricate design, and while they may be more lightweight than rigid endoscopes, this variation is not the primary point of focus in ST91:2021. Additionally, flexible endoscopes are generally designed for multiple uses with appropriate cleaning and disinfection protocols in place, rather than being limited to single use.
