Abstract:
1. A system for treating a gastrointestinal lesion endoscopically using a multidirectional and multiangular approach to the lesion, the system comprising: an endoscope for identifying a lesion in a gastrointestinal lumen of a subject; a multi-luminal tube for use after the identifying of the lesion, the multi-luminal tube having (i) at least one tool channel for an independently manipulable-and-articulable scope to be used in viewing the lesion, (ii) at least one additional tool channel for at least one independently manipulable-and-articulable tool to be used in the treating of the lesion, and (iii) an asymmetrically expandable structure for expanding into an asymmetrical working area distal to the tool channels; wherein, the asymmetrically expandable structure is configured to expand asymmetrically in the direction of the lesion, and push on tissue surrounding the lesion during the expansion, to increase the asymmetrical working area and facilitate an entry of the lesion into the working area for the treating; and, the asymmetrical working area is substantially rigid and stable relative to the independently manipulable-and-articulable scope and the at least one tool to facilitate the treating of the lesion; and, the independently manipulable-and-articulable scope and the at least one tool; wherein, the portion of the asymmetrically expanded structure pushing on the tissue surrounding the lesion is expanded further from the multi-luminal tube than other portions of the structure to provide a larger working area for the treating when compared to a second such structure that merely expands symmetrically around the multi-luminal tube; and, the independently manipulable-and-articulable scope and the at least one tool are independently movable axially in the working area, independently rotatable in the working area, and independently bendable in at least one direction in the working area.
