Abstract:
1. Medical treatment apparatus, comprising: an elongated tube having a proximal end and a distal end adapted to be inserted into a cavity within a living body having a biofilm coating so that the distal end of the tube is disposed within the cavity and its proximal end is exterior of the body, the tube containing a first lumen for introducing fluid into the cavity and a second lumen for suctioning fluid from the cavity; a first port for introducing fluid containing biofilm treatment reducing agents into the proximal end of the first lumen; a second port at the proximal end of the tube for applying a suction force to the second lumen to suction fluid from the cavity; and an ultrasonic generator physically separate from the elongated tube, disposed externally of the body and operative to introduce ultrasonic energy through an external wall of the body and into the biofilm at a power level below the level which will destroy the tissue underlying the biofilm.
