1. An overtube assembly for use with an elongate medical tool, the overtube assembly comprising:
an overtube comprising a flexible tubular body having a proximal end and a distal end, the flexible tubular body including:
a split extending from the proximal end to the distal end; and
circumferentially extending bands distributed along the flexible tubular body, the circumferentially extending bands reinforcing portions of the flexible tubular body;
a longitudinally extending strip; and
a rod adjacent the split and extending along the split, wherein each of the circumferentially extending bands extends from the longitudinally extending strip and each of the circumferentially extending bands is coupled to the rod; and
an inflatable balloon coupled to a distal portion of the flexible tubular body,
wherein the flexible tubular body is disposable over a section of the elongate medical tool by inserting the elongate medical tool through the split.
 
9. An overtube for use with an elongate medical tool, the overtube comprising:
a flexible tubular body having a proximal end and a distal end, the flexible tubular body including:
a split extending from the proximal end to the distal end; and
circumferentially extending bands distributed along the flexible tubular body, the circumferentially extending bands reinforcing portions of the flexible tubular body;
a longitudinally extending strip; and
a rod adjacent the split and extending along the split, wherein each of the circumferentially extending bands extends from the longitudinally extending strip and each of the circumferentially extending bands is coupled to the rod,
wherein the flexible tubular body is disposable over a section of the elongate medical tool by inserting the elongate medical tool through the split.
 
15. An overtube assembly for use with an elongate medical tool, the overtube assembly comprising:
an overtube comprising a flexible tubular body having a proximal end and a distal end, the flexible tubular body defining a first air supply lumen extending from the proximal end to a first overtube port and a second air supply lumen extending from the proximal end to a second overtube port, the flexible tubular body further including:
a split extending from the proximal end to the distal end;
circumferentially extending bands distributed along the flexible tubular body, the circumferentially extending bands reinforcing portions of the flexible tubular body;
a longitudinally extending strip; and
a rod adjacent the split and extending along the split, wherein each of the circumferentially extending bands extends from the longitudinally extending strip and each of the circumferentially extending bands is coupled to the rod;
a first inflatable balloon coupled to an exterior surface of the flexible tubular body on a first side of a distal portion of the flexible tubular body, the first inflatable balloon having a first internal volume and defining a first balloon port, the first balloon port in communication with the first overtube port; and
a second inflatable balloon coupled to the exterior surface of the flexible tubular body on a second side of the distal portion of the flexible tubular body, the second inflatable balloon having a second internal volume and defining a second balloon port, the second balloon port in communication with the second overtube port,
wherein the flexible tubular body is disposable over a section of the elongate medical tool by inserting the elongate medical tool through the split.
