Abstract: 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 selectively asymmetric to maximize space for a tool and an endoscope to visualize a target tissue and treat the target tissue from outside the patient in a minimally invasive manner.

Abstract: A medical device may include a shaft, and a first tool extending from a distal end of the shaft. The medical device also may include a control assembly coupled to the shaft. The control assembly may include a console, a first grip extending proximally from the console, and a second grip extending proximally from the console. The control assembly also may include a first deflection actuator configured to deflect the first tool about a longitudinal axis of the first tool, a first rotation actuator configured to rotate the first tool about the longitudinal axis of the first tool, and a first longitudinal actuator configured to move the first tool along the longitudinal axis of the first tool.

Abstract: This invention is directed to a flexible device having a longitudinal axis, a first elongate member configured to move the flexible device in a first direction relative to the longitudinal axis, and a second elongate member configured to move the flexible device in a second direction relative to the longitudinal axis that is different to the first direction. The flexible device can also have an articulation section including a plurality of articulation links, wherein at least one of the plurality of articulation links can include a body configured to receive the first elongate member and the second elongate member. The flexible device can also include a cinching element configured to engage the first elongate member to substantially limit movement between the plurality of articulation links when a tensile force is applied to the first elongate member and configured to disengage the first elongate member to permit movement between the plurality of articulation links when a tensile force is applied to the second elongate member.

Abstract: A device for treating a tissue opening includes a capsule extending longitudinally from a proximal end to a distal end and including a lumen extending therethrough; a pair of arms movably housed within the lumen of the capsule such that the pair of arms are movable between an open configuration and a closed configuration, the pair of arms being biased toward the open configuration such that when the pair of arms are moved distally with respect to the capsule, distal ends of the pair of arms are separated from one another to receive target tissue therebetween; a needle releasably connected to a first one of the pair of arms, the needle extending laterally inward toward a second one of the pair of arms and including a connecting structure extending along a portion thereof, the second one of the pair of arms including an opening located so that, when the pair of arms are moved to the closed configuration, the connecting structure of the needle engages the opening; and a suture extending from a portion of the needle proximally through the capsule.

Abstract: A medical/surgical device for performing tissue resection can include an endoscope with proximal and distal ends, defining working channels, and a snare assembly located in one of the working channels. The working channel may include a bend near the distal end and towards the outward radial wall of the endoscope. The snare assembly may include a snare loop and an actuation element imparted with the pre-formed angular bends and an actuation control handle. The bends of the actuation element and the working channel may be the same. The rotational manipulation of the actuation element may synchronize the pre-formed bend of the actuation element with the bend of the working channel to concentrically (or otherwise) align the deployed snare loop with the endoscope or endoscope attachments.

Abstract: A tissue closure device includes a needle and a suture extending therefrom, a proximal head including a proximal slot and a proximal locking mechanism for releasably engaging a first end of the needle in the proximal slot in a first configuration, and a distal head movably coupled to the proximal head so that the proximal and distal heads are movable relative to one another between an open configuration, in which a target tissue is received therebetween, and a closed configuration, in which the target tissue gripped therebetween. The distal head includes a distal slot and a distal locking mechanism for releasably engaging a second end of the needle in the distal slot in a second configuration, the needle movable between the first and second configurations by rotating the needle, the needle alternatingly passed between the proximal and distal heads to thread the suture through the target tissue.

Abstract: A device for treating tissue includes a capsule extending longitudinally from a proximal end to a distal end and including a lumen extending therein and a clip slidably received within the lumen of the capsule. The clip includes a middle prong, a first outer prong and a second outer prong. The first prong is coupled to the middle prong so that the first prong is movable relative to the middle prong between a first open configuration and a first closed configuration. The second outer prong coupled to the middle prong so that the second prong is movable relative to the middle prong between a second open configuration and a second closed configuration. The first and second outer prongs are independently movable relative to the middle prong to be moved between the first and second open configurations to the first and second open configurations and the first and second closed configurations.
