摘要： An endoscopic deployment device includes a body mountable on an endoscopic device, a communication interface, and a motor. The body has a movable carrier couplable to an elongated end effector device. The effector device has an end effector shaft covered by an outer sheath and an end effector extending from a distal end of the shaft. The sheath is sized and shaped for insertion through a working channel of an endoscopic shaft of the endoscopic device. The body has a carrier channel sized for the carrier to slide therein. The end effecter is actuatable between open and closed positions by sliding the carrier in the carrier channel which in turn slides the sheath over the end effector shaft to uncover/cover the end effector. Rotation of a drive shaft of the motor is sliding the carrier in the carrier channel and actuating the end effector in response to a signal.

摘要： A medical device may include a plurality of branch members having moveable distal portions. The medical device also may include a first moveable member movably connected to the distal portion of one of the branch members at a first location along the branch member. The first moveable member may have first and second proximal portions extending from the first location and disposed within one or more lumens of one or more of the other branch members. The moveable distal portions of the plurality of branch members and the first moveable member may form a first snare movable between a collapsed configuration and an expanded configuration.

摘要： Systems are described, including a system that includes an insertion device with a shaft and a distribution adapter with a housing and a piston. The shaft includes irrigation and aspiration channels providing a fluid circulation through a target area of a body within which the shaft is inserted. The housing includes first and second pairs of diametrically opposed ports. A first port of the first pair is connected to an irrigation port and a second port of the first pair is connected to the irrigation channel. A first port of the second pair is connected to an aspiration port coupled to a negative pressure source and a second port of the second pair is connected to the aspiration channel. The piston is slidably received within a cavity of the housing to be movable between default and reverse configurations.

摘要： Aspects of stone identification methods and systems are described. According to one aspect, an exemplary method comprises: transmitting to a processing unit, with an imaging element mounted on a distal end of a scope, image data about a stone object inside a body cavity; generating from the image data, with the processing unit, a visual representation of the stone object and the body cavity; establishing from a user input, with the processing unit, a scale for the visual representation; determining from the visual representation, with the processing unit, a size of the stone object on the scale; comparing, with the processing unit, the size of the stone object with a predetermined maximum size to determine a removal status; and augmenting, with the processing unit, the visual representation to include an indicator responsive to the removal status. Associated systems are also described.

摘要： Several embodiments of the present invention are generally directed to medical visualization systems that comprise combinations of disposable and resuable components, such as catheters, functional handles, hubs, optical devices, etc. Other embodiments of the present invention are generally directed to features and aspects of an in-vivo visualization system that comprises an endoscope having a working channel through which a catheter having viewing capabilities is routed. the catheter may obtain viewing capabilities by being constructed as a vision catheter or by having a fiberscope or other viewing device selectively routed through one of its channels. The catheter is preferably of the steerable type so that the distal end of the catheter may be steered from its proximal end as it is advanced with the body. A suitable use for the in-vivo visualization system includes but is not limited to diagnosis and/or treatment of the duodenum, and particularly the biliary tree.
