An endoscope system includes: a first endoscope including a first endoscope connector; a second endoscope including a second endoscope connector; an external apparatus including an apparatus-side receptacle to which the first endoscope connector and the second endoscope connector are connectable; and a converter including a plug connectable to the apparatus-side receptacle, a first receptacle to which the first endoscope connector is connectable, and a second receptacle to which the second endoscope connector is connectable.

Systems and methods are provided for injecting one or more agents into tissue within a patient's body that includes a catheter. A needle guide extends from a distal end of the catheter and terminates at a distal tip, e.g., including a foot with an atraumatic contact surface, the needle guide having a cross-section smaller than the distal end and being biased to a curved shape. The needle guide includes a passage communicating from a lumen of the catheter to an outlet at the distal tip, and a needle device is disposed within the passage that may be deployed from the outlet to inject one or more agents into tissue. The catheter also includes an imaging assembly on the distal end configured to acquire images of tissue adjacent the needle guide distal tip.

In some embodiments, an insertion device for a robotic surgery apparatus can include a first portion with a plurality of instrument channels configured to removably house a plurality of surgical instruments and first and second camera channels positioned in an interior of the first portion and extending along substantially the entire length of the first portion. The first camera channel can removably house a primary camera tube, and the second camera channel can include a secondary camera. The device can include a second portion with an insertion channel terminating at a first end with a first opening permitting the primary camera tube to pass through and terminating at a second end opposite the first end with a second opening aligned with the first camera channel of the first portion. The insertion channel can permit the primary camera tube to pass through the insertion channel and enter the first camera channel.

Improved methods and devices for performing an endoscopic surgery are provided. Systems are taught for operatively treating gastrointestinal disorders endoscopically in a stable, yet dynamic operative environment, and in a minimally-invasive manner. Such systems include, for example, an endoscopic surgical suite. The surgical suite can have a reversibly-expandable retractor that expands to provide a stable, operative environment within a subject. The expansion can be asymmetric around a stabilizer subsystem to maximize space for a tool and an endoscope to each be maneuvered independently to visualize a target tissue and treat the target tissue from outside the patient in a minimally invasive manner.

Devices, tools and methods for performing minimally invasive surgical procedures. Methods of performing minimally invasive ablation procedures. Methods of performing rapid exchange of tools in a device while the device remains in a reduced-access surgical space.

An endoscope aid attachably and detachably attached to a treatment tool insertion channel of an endoscope includes a flexible tubular-member longer than a total length of the treatment tool insertion channel. The tubular-member has a treatment tool insertion pipe line and a suction pipe line. A distal end part of the tubular-member has a sliding contact part that has an outer periphery coming in sliding contact with an inner peripheral surface of an outlet portion of the treatment tool insertion channel maintained in the shape of a straight pipe irrespective of bending of a bending part of the endoscope and is disposed in the outlet portion, and an extending part that extends from the sliding contact part to a distal end side and is disposed to protrude from an outlet of the treatment tool insertion channel. A distal-end-side opening of the suction pipe line is provided in the extending part.

The present disclosure is directed to a medical device. Systems and methods are provided for accessing and visualizing the pancreatico-biliary system. The medical device may include a guide catheter with a first lumen and a second lumen. A first elevator may be disposed in the first lumen, wherein the first elevator is movable relative to the first lumen for elevating a first tool insertable into the first lumen. A second elevator may be disposed in the second lumen, wherein the second elevator is movable relative to the second lumen for elevating a second tool insertable into the second lumen.

Exemplary embodiments of devices and method for affecting at least one anatomical tissue can be provided. A configuration can be provided that includes a structure which is expandable (i) having and/or (ii) forming at least one opening or a working space through which the anatomical tissue(s) is placed in the structure. For example, the structure, prior to being expanding, can have at least one partially rigid portion. In addition, or as an alternative, upon a partial or complete expansion thereof, the structure can be controllable to have a plurality of shapes. Further, the structure can be controllable to provide the working space with multiple shapes and/or multiple sizes.

An endoscope or exoscope having a shaft and at least one objective and at least one electronic image recorder for recording an image of an object field, wherein the objective and image recorder are arranged in a distal end region of the endoscope or exoscope, and includes at least one cable, routed within the endoscope or exoscope, for supply of and/or image transmission from the electronic image recorder, wherein the electronic image recorder includes an optical unit, which is rotatable about a first axis of rotation identical or approximately parallel to a direction of view of the scope, and on which the cable is connected and can be wound on a circumferential surface of the optical unit, and wherein the distal end region includes a cavity, in which storage for holding a section of the cable is held.
