Devices, systems and methods using low frequency ultrasound to emulsify, disintegrate, cut and/or coagulate tissue in a narrow space such as the nasal passages and paranasal sinuses. The devices may comprise a low frequency generator, a functionally active handle, an ultrasound emitter, a concentrator, a waveguide and distal functional tips. The devices and methods are configured to safely and efficiently carry out surgical procedures within the nose and sinuses, among other soft tissues within the body.

To treat body surfaces, such as the sinuses, which are coated with biofilms, the surface is irrigated and suctioned with a fluid which may contain a biocide or other chemical agent for disrupting the biofilm while ultrasonic energy is applied to either the fluid barrier formed over the biofilm or a body surface proximal to the biofilm. Action of the fluid enhanced by the ultrasonic energy tends to remove sections of biofilm which are suctioned out of the site. An electrical field may also be applied to the biofilm to enhance the disruptive action. Apparatus for practicing this method to treat chronic rhinosinusitis comprises an elongated tube adapted to be inserted into sinus cavities through the nose or mouth. The tube includes a first lumen which feeds an irrigating fluid containing biocides and/or biofilm-disruptive chemicals to the treatment site and a second lumen which suctions fluid from the site. An ultrasound horn extends through the tube and its distal end introduces ultrasonic energy into the fluid layer overlying the biofilm. Alternatively, an ultrasound probe may be applied to an adjacent body surface, such as the face over a sinus cavity. In an alternative embodiment, the tube includes a pair of electrodes which establish an electric field across the biofilm, accelerating degradation.

An endoscope for visualizing and operating upon a surgical site within a human body employs an elongated tubular body adapted to be inserted through bodily passages so that the distal end is adjacent the surgical site. The body has a flexible section, at least proximal to the distal end, and manually adjustable bending controls at the proximal end may be manipulated to impose bending forces on the distal end to steer the distal end to the surgical site. A fluid turbine supported for rotation adjacent the distal end is powered by fluids pumped through a passage so as to rotate the turbine. The various cutters and debriding tools may be attached to the distal ends so that they are rotated by the turbine.

Chronic sinusitis is treated by the application of cold plasma or plasma-activated species to the infected mucosal surfaces through use of an endoscope having a steerable end which may be projected into the sinus cavities through the nasal cavity. The cold plasma is generated at either the distal end of the endoscope with a power source by application of a power, or at the distal end by gas and electrical connections extending through the endoscope. The cold plasma or plasma-activated species act to destroy bacterial cells but not eukaryotic cells.
