摘要： An accessory device for an endoscope includes a cap attached to a shaft of the endoscope, the cap extending along a first axis, a first tip coupled to the cap and movable relative to the cap between a deployed configuration and a non-deployed configuration, and a first shaft defining a lumen and extending proximally from the first tip. In the deployed configuration, the first tip extends along a second axis that is offset from the first axis, and in the non-deployed configuration, the first tip extends along a third axis that is offset from the first axis.

摘要： The present disclosure relates generally to positioning elongate members at a target site within a body lumen, such as for acquiring a biopsy from a peripheral airway. Some embodiments are particularly directed to an elongate member with an embedded transducer positioned at a predefined rotational angle with respect to a projected position of an instrument extended out of a distal opening of a first lumen in the elongate member. In many such embodiments, a rotational transducer may be positioned within a second lumen in the elongate member to generate a radial image including indicia of the embedded transducer. Accordingly, an operator may determine a projected position of the instrument prior to extending the instrument out of the lumen. In several embodiments, the embedded transducer may include a forward imaging transducer, such as a fiber optic.

摘要： A device includes a handle, a shaft and a steering mechanism. The handle includes a first actuator for an end effector. The shaft extends from the handle and sized and shaped to pass through a working channel of an endoscope. A distal end of the shaft includes the end effector. A pull wire extends from the handle to the end effector for actuating the end effector. The mechanism includes a second actuator for bending the distal end relative to a longitudinal axis of the shaft. The mechanism includes a first steering wheel having a first steering wire extending therefrom to the distal end of the shaft. Rotating the second actuator rotates the first steering wheel and tensions the first steering wire to bend the shaft, the pull wire for the end effector remaining actuatable when the distal end is bent.

摘要： A device includes a housing having a first opening for receiving tissue therein and a distal head disposed at least partly within the housing. The distal head is configured to rotate about a longitudinal axis of the distal head. The device also includes a first holding member coupled to the housing and a second holding member coupled to the distal head. The first and second holding members are configured so that rotating the distal head stretches a first ligation band coupled to the first and second holding members, permitting tissue drawn into the first opening to pass through an opening of the first ligation band.
