Abstract:
1. An advancing system, comprising: an endoscope having a proximal portion, a distal portion, a working channel extending from the proximal portion to the distal portion, an endoscope aperture disposed at the distal portion and in communication with the working channel, and a port disposed at the proximal portion and in communication with the working channel; an endoscope sheath having a first lumen extending along a first length from a first proximal end to a first distal end, wherein the endoscope is disposed through the first lumen, a second lumen extending along a second length from a second proximal end to a second distal end and configured to receive an elongate medical device, the second lumen being coupled to the first lumen along a majority of the second length of the second lumen, and a first aperture and a second aperture in fluid communication with the second lumen, wherein the first aperture is disposed at the second proximal end of the second lumen, wherein the first aperture is disposed along the proximal portion of the endoscope, wherein the second aperture is disposed at the second distal end of the second lumen, and wherein the second aperture is spaced proximally of a distal end of the endoscope; and further comprising an endoscope cap coupled to the endoscope sheath, the endoscope cap enclosing the distal end portion of the endoscope there within and having a distal end that is spaced distally of the endoscope aperture, the endoscope cap comprising a non-movable ramp disposed on an outer surface thereof, the ramp being configured to deflect an elongate medical device delivered through the second lumen along an angled pathway that extends outwardly and away from a longitudinal axis of the endoscope.
