Abstract: A medical device includes a shaft including a distal end including a passive electrode that defines a central opening extending through the passive electrode, and an active electrode within the central opening. The active electrode is movable between at least an extended position in which the active electrode does not contact the passive electrode, and a retracted position in which the active electrode contacts the passive electrode.

Abstract: According to one aspect, a medical system may include an instrument including an end effector for acting as a monopolar electrode. The end effector may be configured to be positioned in a body of a subject and emit radiofrequency energy towards a target area in the body. The medical system may further include a return electrode. The return electrode may be deliverable within the body proximate the target area and separately from the instrument and the monopolar electrode. The return electrode may be configured to contact tissue in the body proximate the target area and receive radiofrequency energy emitted from the end effector.

Abstract: A medical system having a medical tool, including a handle, a shaft extending from the handle and defining a lumen, a wire attached to and extending from the handle through the lumen, expandable elements at a distal end of the wire. An electrical generator is coupled to a proximal end of the wire and supplies a first waveform to the wire and the expandable elements as the expandable elements expand from an unexpanded state to an expanded state within a tissue. The electrical generator supplies a second waveform to the wire and the expandable elements when the expandable elements are in the expanded state within the tissue. The first waveform cuts tissue, the second waveform ablates tissue using radiofrequency ablation or irreversible electroporation.

Abstract: According to one aspect, an instrument may include a sheath having a distal end. The instrument also may include a fluid cannula at the distal end of the sheath. The instrument also may include a cutting electrode at the distal end of the sheath. At least one of: (i) an exterior surface of the fluid cannula, and (ii) a cutting electrode surface that faces the exterior surface, is longitudinally slidable along the other of the exterior surface and the cutting electrode surface during movement of at least one of the cutting electrode and the fluid cannula relative to the other of the cutting electrode and the fluid cannula.

Abstract: A medical device includes a shaft including a central lumen configured to direct a flow of fluid through the shaft, and an electrode positioned at a distal portion of the shaft. The electrode includes an electrode lumen in fluid communication with the central lumen, and the electrode lumen is configured to receive the flow of fluid from the central lumen. The electrode also includes one or more channels angled relative to the electrode lumen, and the one or more channels are in fluid communication with the electrode lumen to receive the flow of fluid from the electrode lumen. The one or more channels are configured to divert the flow of fluid from the electrode lumen toward one or more outlets laterally offset from the electrode lumen.

Abstract: A system for controlling the flow of fluid through a medical device may include a medical device having a lumen that extends to a distal end of the medical device; a fluid source configured to supply fluid having a positive pressure to the lumen of the medical device; and a flow controller configured to apply a negative pressure to the fluid within the lumen, wherein the flow controller is triggered to apply the negative pressure upon a lowering of the positive pressure from the fluid source.

Abstract: A medical device includes a shaft including a lumen configured to direct a flow of fluid through the shaft and an electrode. A proximal end of the electrode and a distal end of the shaft form a coupling configured to releasably couple the proximal end of the electrode with the distal end of the shaft. When the proximal end of the electrode is coupled to the distal end of the shaft, fluid delivered through the lumen is emitted from the electrode.
