An insertion assist tube for an endoscope includes an insertion assist tube body and a fluid suppression member. The insertion assist tube body has a pipe line through which an insertion part is inserted, and an opening portion. The fluid suppression member is provided in the opening portion to suppress passage of a fluid. The fluid suppression member has a first porous member on which a first slit is formed, and a second porous member on which a second slit intersecting the first slit is formed.

An endoscope system includes an endoscope and a processor device that includes a system controller formed of an image control processor. The system controller determines whether or not the endoscope is a length measurement-compatible endoscope in a case where the endoscope is connected to the processor device, and enables switching of a mode to a length measurement mode in a case where the endoscope is the length measurement-compatible endoscope.

Technologies are generally provided for a tissue removal device for removing tissue protrusions extending from a wall of intestines. The tissue removal device may be a bell shaped tube configured to slide over an inflamed diverticulum that has been inverted to extend into interior space of the colon. The tissue removal device run be slid over the inverted diverticulum with a portion of the tissue removal device having a widest diameter oriented near the colon wall and a portion having a narrowest diameter oriented near a tip of the diverticulum. A pressure gradient may be induced along the walls of the tissue removal device such that the point of highest pressure at the narrowest opening may cause the walls of the diverticulum to be pinched together to induce necrosis and removal of the diverticulum, while promoting healing of the colon walls over the region of decreasing pressure.

A gas supply apparatus includes: a gas supply conduit for supplying a gas to a digestive tract; a pressure detecting device which detects a pressure in the digestive tract; a flow regulating device which regulates a gas amount supplied from the gas supply source to the digestive tract via the gas supply conduit; a first control device which controls the flow regulating device according to a result detected by the pressure detecting device to supply the gas into the digestive tract so that the pressure inside the digestive tract becomes a set pressure; a second control device which controls the flow regulating device to supply a fixed gas amount into the digestive tract; and a gas supply mode switching device which switches between gas supply modes including a mode for executing control by the first control device and a mode for executing control by the second control device.

An endoscopy support system, including an extendable primary wrap comprising a band of elastic material sized for placement around a lower abdomen of a subject and at least one elastic, secondary strap having a first end fixed to the primary wrap and a second end comprising a coupling mechanism for removably coupling the second end to the primary wrap, wherein the at least one elastic strap is configured to extend in a left to right direction across a front abdomen portion of the primary wrap in order to exert an additional targeted force to a portion of the abdomen of the subject. The system further includes at least one extension piece having an attachment mechanism to removably couple to the primary wrap or the at least one secondary strap.
