TLDR
In this paper, an endoscope with a plurality of potential channels is described, where the tube is expanded by placing a tapered rod or fluid under pressure along the length of the insertion tube, or by elevating a flat coil into a cylindrical coil.Abstract:
An apparatus and method for providing an endoscope with a plurality of potential channels is disclosed. A tubing (54) having a radially flexible wall is positioned adjacent the endoscope insertion tube (34). The tubing (54) is collapsed prior to inserting the insertion tube (34) into the patient's body. After the insertion tube (34) is within the patient's body, the tubing (54) is expanded to create a channel. A medical apparatus may pass through the channel for performing a medical procedure. The tubing (54) is expanded by placing a tapered rod therethrough, by placing a fluid under pressure within the tubing (54), or by elevating a flat coiled wire into a cylindrical coil. A radially rigid tubing is placed within the expanded flexible tubing (54) to permit medical devices to extend from a position outside of the patient's body to the distal end of the insertion tube (34). A plurality of tubings (54) are provided circumferentially spaced from each other around the insertion tube (34) to permit a combination of medical devices to be used in cooperation with each other to perform a medical procedure. A stiffening member, such as a rod or fluid under pressure may extend partially along the length of the insertion tube (34) to vary the flexibility characteristics of the insertion tube (34) while it is within the patient's body.read more
