Abstract: 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.

Abstract: A device includes a capsule along with first and second clip arms, proximal ends of which are received within the channel so that the first and second clip arms are movable relative to one another between an open configuration and a closed configuration. A deployment mechanism includes a tension member connected to a proximal end of the first and second arms, a yoke releasably coupled to the tension member and longitudinally movable relative to the capsule to move the first and second arms between the open and closed configurations. The tension member and yoke are configured to separate from one another in response to a predetermined proximal force relative to the tension member. A locking mechanism is coupled to the deployment mechanism and is configured to engage the capsule to lock the one-piece clipping element in the closed configuration, when the yoke is separated from the tension member.

Abstract: A device includes a flexible insertion section extending from a distal end which, during use is inserted to a target site to a proximal end which remains outside the body; an end effector coupled to a distal end of the insertion section; and a control wire received within the insertion section and extending from a proximal end coupled to an actuator to a distal end coupled to the end effector. The control wire is movable within the insertion section to operate the end effector. The control wire and the insertion section include a bend in a distal portion thereof configured so that, in a resting state, the control wire and the insertion section bend through a predetermined arc at a selected bending radius. A distal portion of the control passes into and through a working channel of an insertion device without plastic deformation of the control wire.

Abstract: 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.
