    摘要： Methods and devices are provided for controlling movement of a working end of a surgical device. In one embodiment, methods and devices are provided for moving an end effector on a distal end of a surgical fastening device. Movement can include rotational movement of the end effector about an axis of the shaft, articulation of the end effector relative to the shaft, and actuation of an end effector, e.g., closing, firing, and/or cutting. In other embodiments, a single cable actuator is provided and is movable between a first position, in which it is effective to rotate an end effector without actuating (i.e., closing and firing) the end effector, and a second position, in which it is effective to actuate the end effector without rotating the end effector. In other aspects, methods and devices are provided for moving a flexible neck formed on a distal end of an accessory channel for use with an endoscope. Movement of the flexible neck can be used to control positioning of a tool extending through the flexible neck.

    摘要： An exemplary anastomosis device comprises a proximal ring, a distal ring, and a middle ring. The middle ring has apertures configured to communicate a fluid such as an adhesive. The exemplary anastomosis device also has arms joining the proximal ring to the center member and arms joining the distal ring to the center member. The anastomosis device is configured to move from an unactuated position, where it has a generally cylindraceous configuration, to an actuated position, where it has a generally rivet-like configuration. The anastomosis device may be used to provide and secure an anastomosis between adjacent tissue walls. Adhesive may be communicated through the apertures of the middle ring of the anastomosis device to seal or strengthen the anastomosis. An applier may be used to deploy the anastomosis device and to communicate the adhesive through the apertures.

    摘要： Methods and devices are provided for regulating a restriction system. In one exemplary embodiment, a restriction system is provided having a restriction device coupled to a port with a fluid disposed in the device, such that the restriction device is adapted to form a restriction in a pathway corresponding to an amount of fluid contained in the device, and a pressure adjustment unit in communication with the port and effective to maintain a substantially constant equilibrium pressure between the pressure adjustment unit and the restriction device. The pressure adjustment unit is configured to regulate an amount of fluid in the restriction device in response to a fluid pressure acting on the device.

    摘要： A gastric reduction apparatus endoscopically draws stomach walls into apposition. The apparatus includes an applicator body having a proximal end and a distal end. The applicator body also includes a suction slot shaped and dimensioned for housing a corkscrew anchor. A firing mechanism is associated with the corkscrew anchor for rotation of the corkscrew anchor in a manner causing the corkscrew anchor to penetrate and engage tissue brought adjacent the suction slot. A method for gastric reduction is achieved by introducing a gastric reduction apparatus as disclosed above within the stomach of an individual, applying the corkscrew anchor to a stomach wall and drawing stomach walls together to create a cavity within the stomach.

    摘要： An anchorable cannula adapted for positioning within an opening formed in tissue includes a cannula body having a proximal portion and distal portion. The proximal portion and the distal portion are linked by a circumferential ring positioned therebetween. The proximal portion includes a series of foldable arms extending upwardly from the circumferential ring and ending at a circumferential seal ring formed at a free end of the proximal portion. The distal portion includes a series of foldable arms extending downwardly from the circumferential ring and ending at a circumferential seal ring formed at a free end of the distal portion.
