Abstract: A cryotherapy system, including: an endoscope including: an elongated insertion tube having a distal tip shaped and sized to penetrate into a hollow organ; a working channel within the elongated insertion tube including a proximal opening and a distal opening at the distal tip; a cryocatheter including: at least one cryofluid channel with at least one distal opening positioned to release cryofluid into the hollow organ; at least one washing fluid channel with at least one washing fluid distal opening; wherein the cryocatheter is shaped and sized to controllably move within the working channel and to extend at least partly from the working channel distal opening, to position the at least one washing fluid distal opening in a selected distance and/or orientation relative to the elongated insertion tube distal tip.

Abstract: According to some embodiments of the invention there is provided a colon cleaning system comprising: a working channel, a vacuum source, a separate vacuum pipe provided alongside the working channel, and a sensor positioned at a conduit connected externally to the working channel, the sensor configured for providing an indication related to pressure within at least a segment of the working channel. In some embodiments, the system comprises a controller configured for controlling one or more parameters of a vacuum induced in the separate vacuum pipe, the parameter determined according to the pressure related indication provided by the sensor.

Abstract: Systems and methods for cleaning a colon or other portion of an intestine include optional use of sensors to detect conditions of blockage of flow of materials within an evacuation channel used to remove fecal material from the body; and devices and methods for purging such blockages from the evacuation channel.

Abstract: Methods of colon cleansing and/or inspection are described which safely maintain a colon in an uncollapsed state. Balanced replacement of a volume of fluid, gas and/or solids evacuated during cleansing of the colon is described. Replacement volume comprises, for example, cleansing fluid, jetting gas, and/or inflation gas. In some embodiments, balancing of evacuated and replacement volume is achieved under automatic control, based on monitored volume of material exchange, and/or measurement of resulting pressures.

Abstract: Methods for clearing of fecal matter the wall of a colon or other body lumen for diagnostic inspection, the methods being adapted to clearing of fecal matter comprised of particles of various sizes and compositions. Methods are further adapted for application in patients who have undergone a restricted scope of preparation to reduce and/or remediate the particle structure of colon contents, or no preparation at all, before diagnostic inspection.

Abstract: An integrated endoscope cleansing system (IECS) comprises both an independent cleansing system (ICS) evacuation conduit in communication with an independent cleansing system working station (IWS), and an endoscope insertion tube with a working channel functionally coupled to a vacuum source, under control of an endoscope working station (EWS). In some embodiments, the ICS evacuation conduit is located within the insertion tube, while being functionally coupled to an ICS vacuum source, controlled by the IWS.

Abstract: Devices for joining an endoscope with a system for cleaning a colon or other body lumen are presented. Embodiments include variable placement of distal portions of suction components with respect to the endoscope, multiple suction tubes and/or suction portals, and devices for protecting colon walls from suction damage.

Abstract: A sleeve assembly is described for coupling a colonoscope insertion tube to an add-on tube. In some embodiments, the sleeve assembly defines an elongated lumen and comprises an inner sleeve sized to receive an insertion tube of a colonoscope, an outer sleeve encircling the inner sleeve, and one or more add-on tubes positioned between the inner sleeve and the outer sleeve. In some embodiments, at least the inner sleeve is collapsible to fit tightly over a colonoscope insertion tube received within the inner sleeve. In some embodiments, the inner sleeve is coupled to the outer sleeve at one or more locations along the length of the inner sleeve so that collapsing of the inner sleeve brings the outer sleeve radially closer to the inner sleeve, approximating the one or more add-on tubes to a colonoscope insertion tube received within the inner sleeve.
