    Abstract: An endoscopic device includes a handle body operatively couplable to a shaft housing. The handle body includes an actuator for controlling a distal end of an endoscopic shaft extending from the shaft housing. The device also includes a pull wire attachment configured to operatively couple to a pull wire extending through the shaft housing and the endoscopic shaft to the distal end. Applying tension to the pull wire deflects the distal end of the endoscopic shaft. In addition, the device includes a pulling mechanism coupled to the actuator and having the pull wire attachment extending therefrom. When the pull wire attachment is operatively coupled to the pull wire, actuation of the actuator applies tension to the pull wire and deflects the distal end of the endoscopic shaft.

    Abstract: Single use medical devices and mechanisms for preventing the re-use thereof. A single use medical device may include a housing defining an insertion slot and a lockout mechanism. The lockout mechanism may comprise a biasing mechanism and a movable slide element positioned adjacent to the insertion slot and the biasing mechanism, the slide element movable between a pre-use configuration, an in-use configuration, and a post-use configuration. The slide element may be actuated via an insertion member removably inserted into the insertion slot.

    Abstract: A medical device configured to be actuated using a first hand may include a handle comprising a proximal handle portion and a distal handle portion, an elongate shaft extending distally from the distal handle portion, wherein the elongate shaft includes a distal tip that is deflectable using a first actuation mechanism secured to the proximal handle portion, wherein the handle includes a port in communication with the elongate shaft, and an actuatable medical instrument configured to be slidably disposed within the elongate shaft and the port. A proximal end of the actuatable medical instrument may be operably connected to a second actuation mechanism secured to the proximal handle portion. The first actuation mechanism may be configured to be actuated by a thumb of the first hand. The second actuation mechanism may be configured to be actuated by the thumb of the first hand.

    Abstract: According to an example of the present disclosure, a retrieval device having a contracted state and an expanded state may include at least three support members each having a lumen, a fixed proximal end, and a movable distal end, and at least two members movable relative to the support members. Each movable member may include a first end and a second end and extending distally through a lumen of a support member and proximally through a lumen of a different support member. The device may include a stop located at the second end of at least one movable member to restrict movement of the second end after moving a distance distally during movement of the retrieval device toward the expanded state.

    Abstract: Aspects of a device are described herein. The device may comprise: a housing including a track with a plurality of segments; a plunger including a pin located in the track; a sheath extending distally from the housing; a wire extending distally from the plunger into the sheath; and an end effector on a distal end of the wire, wherein the housing is movable relative to the plunger to move the pin between the plurality of segments, and each of the plurality of segments corresponds with a position of the end effector relative to the sheath. Related devices, kits, and methods also are disclosed.

    Abstract: A medical device may include a luminal body defining a working channel extending between a proximal end of the luminal body and a distal end of the luminal body. The device may also include a carrier defining a pusher thereon. The carrier may be configured to transition between a first state and a second state. In the first state, a distal portion of the carrier may extend within the working channel along a central longitudinal axis thereof. In the second state, the distal portion of the carrier may extend distally of the luminal body. The device may also include a plurality of anchors which may be disposed about the carrier. Also, at least a distal-most anchor of the plurality of anchors may define a surface configured to cooperate with the pusher and further defines a curved wall configured to cooperate with the pusher to rotate the plurality of anchors.
