An endoscopic examination supporting apparatus includes at least one processor including hardware. The processor acquires insertion shape information indicating an insertion shape of an insertion section of an endoscope inserted into a subject, evaluates, based on the insertion shape information, a procedure including inserting operation for the insertion section performed by a user who operates the endoscope during an endoscopic examination, and generates procedure evaluation information.

Improved methods and devices for performing an endoscopic surgery including a system for performing minimally invasive procedures including a flexible catheter having a working space expanding system positioned at a distal portion, the working space expanding system movable from a non-expanded insertion position to an expanded position forming an expanded region to expand the working space within the body lumen. A tissue retractor having an inner member positioned within an outer member has a plurality of closed loops at a distal portion forming a petal-like structure. The loops are positioned in a collapsed position within the outer member and are movable to an expanded position when exposed from the outer member.

A system and method for delivering irreversible electroporation treatment to a selected tissue includes introducing an endoscope into a position adjacent the selected tissue, and advancing first and second probes having electrodes at their distal ends. One probe may be inserted into the lesion or tumor and remain in place while the other probe is moved around the tumor, with activation of the electrodes occurring at each location of the probes.

A removal tool for removing a hood having a hollow cylindrical shape mounted to a distal tip of an endoscope from the distal tip is constituted from a flexible member including a hole-shaped recess capable of housing the hood in its inside. An outer surface of the hood is provided with a step portion that extends along a circumferential direction of the hood. An inner wall surface of the recess is provided with an engaging portion at a position opposing to the step portion when the hood is housed in the recess, the engaging portion being shaped to grip the hood by being engaged with the step portion as a result of deformation of the flexible member.

A device includes an anoscope including an elongated hollow member with a longitudinal slot configured to receive tissue in an interior of the hollow member. The device also includes a clip applicator. The clip applicator includes a body slidably received in the slot and jaws at a distal end of the body configured to hold a ligation clip. The clip applicator further includes a plunger slidably coupled to the body configured to actuate the jaws. When the clip applicator is inserted into the slot and the plunger is moved relative to the body, the jaws close and deform the ligation clip from an open position into a closed position around tissue received in the slot.

A system for closing a blood vessel includes a housing having a proximal end and a distal end and configured to be held in the hand of a user, an elongate body extending from the distal end of the housing, a distal housing having a proximal end coupled to a distal end of the elongate body and having a cavity including an opening on a side of the distal housing, a lumen passing through the elongate body and terminating at the cavity of the distal housing and configured to couple to a vacuum source, a sensor carried by the distal housing adjacent the cavity and configured for identifying a blood vessel, wherein the lumen is configured to maintain a vacuum within the cavity when a probe having a vessel closure module is inserted within the lumen and the vessel closure module is within the cavity.

Provided is a scope that can comprise a tubular casing, a proximal end, a distal end, an internal volume, a longitudinal axis of extension extending from the distal end to the proximal end, a vertical axis extending perpendicularly to the longitudinal axis of extension and one or more apertures along a length L of the longitudinal axis of extension; a handle having a proximal end and a distal end; and image capture devices each located within the internal volume of the tubular casing.
