Abstract: Medical devices and related methods are discussed, including a medical device that includes a handle with a housing and an actuator mechanism disposed within the housing. The actuator mechanism may include a biasing member and a disk rotatable between a first position and a second position, e.g., the biasing member having a first length and exerting a first distal force on the disk in the first position, and having a second length different from the first length and exerting a second distal force on the disk less than the first distal force in the second position.

Abstract: A scope adapter system includes an adapter body coupled to a handle of a scope device, a rigid shaft, and a mounting mechanism removably coupled to the shaft. The shaft includes a shaft lumen which is sized and shaped to slidably receive a flexible elongated member of the device. A distal end of the lumen is sized so that, when a distal end of the member is received therein, the distal end of the member is snugly held so that an aim of the shaft aims the distal end of the member. The mechanism mounts a proximal end of the shaft to the body so that, when the body is coupled to the handle, the mechanism is mounted on the body and coupled to the shaft and the member is inserted into the lumen so that movement of the handle effects corresponding movements of the distal end of the member.

Abstract: A medical accessory mounting system may include a medical device having a handle and an elongate shaft extending distally from the handle. The handle may include at least one connecting structure formed in an outer surface of the handle, the at least one connecting structure comprising a plurality of ridges. The at least one connecting structure may be configured to engage with an accessory connecting structure formed on an outer surface of an accessory device.

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: Systems and methods for treating a patient may include accessing an anatomical structure with a single use visualization device, using the imaging capabilities of the single use visualization device within the anatomical structure, and in some cases, advancing the single use visualization device beyond the anatomical structure to and toward another anatomical structure within the patient. Disposable elements may be used with or added to the single use visualization device to accomplish tasks normally performed with reusable devices.
