Abstract: A system for performing minimally invasive procedures in a working space within a body lumen of a patient including a flexible catheter configured to receive a working instrument therethrough. The flexible catheter has a working space expanding system positioned at the distal portion, the working space expanding system including first and second flexible elements movable from a non-expanded insertion position to an expanded position forming an expanded region to expand the working space within the body. The first and second flexible elements are connected at a distal region by a coupling structure. A stabilizing member stabilizes the distal portion of the flexible catheter.

Abstract: An endoscopic treatment method includes: inserting an endoscope into a digestive tract; forming a damaged area in at least a portion of the digestive tract along a circumferential direction by performing cauterizing while keeping a mucosal layer by observing with the endoscope; and forming an incomplete stenosis in the digestive tract, while restoring the damaged area, wherein the damaged area is formed by causing damage to a mucosal base layer, the mucosal base layer having an interface that contacts a submucosal layer.

Abstract: Exemplary embodiments of the present disclosure relate to devices, systems, and methods for tissue resection in a body lumen of a patient, and may include an endoscope and a backstop delivery device extendable through the endoscope. The backstop delivery device may deliver a backstop to a location of selected tissue for resection. A backstop may include a covering being deployable in a patient. The covering may have one or more anchoring mechanisms disposed on an edge of the covering. A tissue resecting device may be extendable through the endoscope for resecting the selected tissue for resection. The covering may be deployable to an outer surface of the body lumen, such that the anchoring mechanism may secure the covering to the outer surface of the body lumen and the covering may expand to cover the selected tissue for resection.

Abstract: An auxiliary apparatus for MIS including an in vivo device and an in vitro device to stretch a surgery target is provided. The in vitro device comprises an in vitro magnet field-generating element. The in vivo device comprises an in vivo magnet-anchoring element to the surgery target. The in vivo magnet moves and/or rotates according to the direction change of the external magnetic field, which is generated by the in vitro magnet field-generating element, and thereby the surgery target can move in a controlled speed and/or rotate in a controlled angle according to the direction change of the external magnetic field. A method to control the auxiliary apparatus is also provided.
