    Abstract: A retrieval device may include a sheath including a distal end and a proximal end, and an end effector at the distal end. At least a portion of the end effector may be movable relative to the sheath between extended and retracted states. The end effector may include a support member extending from the distal end of the sheath, and a movable member extending from the distal end of the support member. The device may include a handle assembly at the proximal end of the sheath, having an actuation member for transitioning the end effector between the extended and retracted states. The device may include a biasing member coupled to at least one of the actuation member and the sheath that may control a force, exerted by one of the movable members and the support member on the other, generated by relative movement between the movable and support members.

    Abstract: A medical device may include an introducer sheath, having a distal and a proximal end and a lumen extending from the distal end to the proximal end. The introducer sheath may also include a tab formed at the distal end and extending distal to the lumen, and a frangible portion extending between the distal end and the proximal end.

    Abstract: A retrieval device attachable to a scope includes a handle which has an attachment portion configured to couple the handle to the scope; a shaft coupled to the handle having a wire immovably coupled to the handle; and a sheath movable relative to the handle over the wire between a distal position and a proximal position via an actuator of the handle. The actuator actuates a slider assembly of the handle. The slider assembly is coupled to the sheath and movable relative to the attachment portion to move the sheath and an expandable end effector coupled to the distal end of the wire. The end effector is movable between a collapsed configuration when the sheath is moved distally to the distal position to cover the end effector and an expanded configuration when the sheath is moved proximally to the proximal position, uncovering the end effector.

    Abstract: A ureteroscope system includes a handle; an elongated shaft extends from the handle to a distal end and includes a working channel which is opened at the distal end; an external member extends from a proximal end to a distal end and is coupled to the shaft, the member includes a hub and a tube defining a first external channel; and a coupling mechanism defines first and second tubes and is coupled the distal end of the member to the distal end of the shaft. The first tube defines a first lumen and the second tube defines a second lumen which is sized and shaped to receive a distal end of the member. A proximal portion of the first tube is sized and shaped to be inserted into a distal portion of the shaft such that the first lumen is opened to the working channel.

    Abstract: A system for modularly assembling a scope device includes an optical module which has an optical housing and a longitudinal member extending distally therefrom. A distal end of the member includes a camera for visualizing a target area, electric wires and a light source extending from the camera to the optical housing. The system also includes a deflector module coupleable with the optical module. The deflector module includes a deflector housing and a deflector shaft extending distally therefrom. The shaft includes a first channel sized, shaped and configured to receive the member therein and a deflectable portion extending along a distal portion of the shaft. The deflector housing includes an actuator for deflecting the deflectable portion, the optical and deflector housings including corresponding connecting elements to engage one another when the member is inserted through the first channel and the deflector and optical housings are coupled.

    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.
