ENDOSCOPE WITH SHARED WORKING CHANNEL

摘要

Multiple tasks may be performed in a lumen of a living creature accessible via a path. One or more guides are optionally supplied. Optionally the guides communicate with a working channel of an endoscope. A tool may be conveyed along a guide through the working channel of the endoscope. For example a first tool may be conveyed to the lumen unblocking the working channel for a second tool. Optionally the second tool may subsequently be conveyed along a second guide. In some embodiments the guides may include thin channels in communication with the working channel via a longitudinal slit. Optionally the working channel may include a slit. For example large objects may be conveyed along the working channel partially protruding from the longitudinal slit.

1. A catheter for transporting material between outside a living creature and a region inside the living creature comprising:
a sleeve including:
a working channel including a proximal opening for access from outside of the living creature and a distal opening for positioning inside the region of the living creature;a plurality of elongated guides extending along at least a portion of a length of said working channel, each of said guides in communication with said working channel along at least 5 cm of a length thereof;a tool transportable between a first location outside said proximal opening, a second location inside said working channel and a third location outside said distal opening; anda carriage mating to at least one guide of said plurality of elongated guides; said carriage connected to said tool off center of a cross section of said tool, traveling along said at least one guide from a proximal position to a distal position thereby conveying said tool from said second location to said third location, and rotating around an axis of said at least one guide in said distal position thereby moving said tool to a fourth location away from an axis of said working channel.
