Abstract (en)
[origin: WO9006717A1] A method of inserting an instrument into the gastrointestinal tract of a mammal, by emplacing at least a portion of a flexible liner (50) to form within the intestine an inner tube within an outer tube, the inner tube defining a lumen lying within the intestine and having a distal end accessible via the anal opening from outside the body of the mammal, and thereafter passing the insrument to the lumen via its distal end. Another aspect is the combination of an elongatge evertible liner (50), a liner support chamber (12) having a proximal port (18) and a distal port (22), the liner having its two ends attached respectively at the ports, and a pressurizer for increasing the pressure within the chamber to cause the liner to be everted.
