Abstract:
1. A sheath for receiving a plurality of endoscopic instruments within separate channels thereof, comprising: a cross-sectional outer diameter and an inner diameter; terminally opposed proximal and distal ends, wherein the cross-sectional outer diameter of the distal end is adapted to be inserted into a working channel of an endoscopic device and wherein the cross-sectional outer diameter of the sheath defines an approximately hyperbolic shape that permits gas or fluid flow between an outer surface of the sheath and an inner surface of the working channel of the endoscopic device when the sheath is positioned therein; a length that is the distance between the proximal end and the distal end along a central axis between the proximal end and the distal end; a first channel and a second channel disposed longitudinally within the sheath, the each one of the first channel and the second channel having: wherein at least one of the first channel or the second channel comprises an open edge open along at least part of the length of the respective channel, and wherein the sheath is adapted to be positioned within, and removable from, a working channel of an endoscopic device before, during and after deployment of the endoscopic device to a procedure site.
