Disclosed embodiments include apparatuses, systems, and methods for positioning electrodes within a body. In an illustrative embodiment, an apparatus for slidably moving multiple features relative to a sheath insertable into a body and positionable relative to a reference point includes a primary actuator configured to move a primary electrode to a first position. A secondary actuator is configured to move a secondary electrode to a second position. A shrouding device is configured to selectively prevent access to the secondary actuator until the primary actuator has been manipulated to extend the primary electrode to the first position.

User interface and lock features for positioning multiple components within a body

Disclosed embodiments include apparatuses, systems, and methods for positioning electrodes within a body. In an illustrative embodiment, an apparatus for slidably moving multiple features relative to a sheath inserted into a body and positioned relative to a reference point includes a primary actuator configured to move a primary electrode, a secondary actuator configured to move a secondary electrode, and a control mechanism. The control mechanism is configured to selectively prevent movement of at least one of the primary actuator based on a position of the secondary actuator and of the secondary actuator based on a position of the primary actuator and lock positions of the primary actuator and the secondary actuator.

An apparatus for controlling advancement of a sheath or a catheter at a distal end of an endoscope. An exemplary apparatus includes a flexible sheath that receives a medical device within an internal lumen and is received within a working channel of an endoscope. The apparatus also includes a component that is at least one of external or internal to the sheath. The component causes a change in longitudinal motion friction of the sheath above a predefined threshold amount as the sheath moves relative to an exit ramp of the endoscope.

Sheath location indicator and overextension preventer

Disclosed embodiments include apparatuses for holding an endoscope handle and locking out an angulation lever of an endoscope handle. Given by way of illustration only and not of limitation, in an embodiment an illustrative apparatus includes: a frame; a support mechanism attached to the frame and configured to hold thereon an endoscope handle having an angulation lever; an attachment device configured to hold an endoscope handle in place on the support mechanism; and an angulation lever engagement mechanism configured to prevent an angulation lever of an endoscope handle from returning to a neutral position.

Endoscope handle holder with angulation lever lock-out

An electrosurgical device includes a needle with an interior surface defining a lumen and a first electrode positioned within the lumen of the needle in a first position. The first electrode is movable within the needle between the first position and a plurality of other positions. The first electrode extends beyond a distal end of the needle in the plurality of other positions and includes one or more anchors that pierce into a predetermined portion of tissue in an anatomy of a patient. The first electrode is energized to ablate the predetermined portion of tissue with the first electrode.
