A method and apparatus for ultrasonically cleaning the interior of a flexible, elongate, tubular medical instrument, such as an endoscope, laparoscope, or the like involves the generation of both longitudinal and transverse ultrasonic waves in a fluid medium within the interior channel or lumen of the instrument. The ultrasonic waves are generated within the instrument by a flexible wire resonator coupled to and responsive to an ultrasonic transducer and generator.
