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.

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.

Certain aspects relate to systems and techniques for an endoscopic system to access, visualize, and treat pathologies in various organs via natural orifices and lumens of various organs. In one aspect, the system includes an elongate shaft configured for insertion into a urinary tract of a patient. The elongate shaft can include a proximal section, a distal section, a tip portion, and a plurality of pull wires extending along the elongate shaft and terminating at the tip portion of the elongate shaft. The plurality of pull wires may include a first and second pull wire. The first pull wire may be configured to articulate each of the proximal section and the distal section in a first direction. The second pull wire may be configured to articulate the distal section in a second direction independently of the proximal section, the second direction being transverse to the first direction.

A basket device for an endoscope includes a base tube attached to an end of an endoscope tube and including at least one channel through which an endoscopic camera or a surgical instrument passes, a plurality of baskets provided at locations separate from each other in a radial direction along an edge of an end of the base tube and formed to protrude in a direction in which each of the baskets is to be expanded, and an operator formed to surround the plurality of baskets at the end of the base tube and being slidable in a longitudinal direction of the base tube.

An adaptor may include a shell and a plunger positioned at a first end of the shell and moveable between an undepressed state and a depressed state. The adaptor may further include a ramp extending from a second end of the shell and a carrier coupled to the ramp. In the undepressed state, the carrier may be located at a first position along the ramp, and wherein, in the depressed state, the carrier may be located at a second position along the ramp, wherein the second position may be closer to the second end of the shell than the first position.

A tool for use by a surgeon for operating a basket device for capturing an object to be removed from a body of an animal. The tool includes a first controller and a second controller. The first controller is adapted to be coupled to the basket device for selectively controlling the basket device and moving the basket device between a first, closed position and a second, open position. The first controller includes a plunger and cylinder mechanism; and a handle coupled to the plunger for operating the relative position of the plunger with respect to the cylinder. The second controller is positioned adjacent to the first controller and adapted to be coupled to the basket device for selectively independently controlling the rotation of the relative to the first controller.

According to an embodiment, an autonomous endoscopic system capable of controlling movement of an endoscope inserted into a protective sheath installed in the body of a patient may comprise: an endoscope operating device capable of operating a relative position of the endoscope with respect to the protective sheath, a rolling angle of the endoscope, and a bending angle of a bending portion which is located at the end of the endoscope and is bendable; and a control unit for controlling the endoscope operating device, wherein the control unit controls the endoscope operating device on the basis of a driving record of the endoscope.

A device for distending a body lumen for enhanced visualization with a capsule endoscope that includes a camera lens includes an attachment element configured to attach to the capsule endoscope and a plurality of struts extending from the attachment element and meeting at an apex. The plurality of struts are configured to extend both axially and radially away from the camera lens so as to form a frame therearound.

A robotic assembly comprises a deployment catheter including a steerable distal region and further comprises a balloon assembly coupled to the steerable distal region.
