A device (10) and method for cleaning and sterilizing tubular structures (94, 96) particularly narrow tubular structures (94, 96) such as lumens (14) of a medical device such as an endoscope (12) by reversing the flow of fluid in interconnected tubular structures (94, 96). The device comprises a first (80) and second (82) valve in fluid communication with a first (94) and second (96) tubular structure. The valves (80, 82) selectively switch between a first and second flow path within the tubular structures (94, 96), at least a part of the second flow path opposite the first flow path. |
