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: A valve may have a fluid inlet and a fluid outlet. The valve may include a valve stem having a lumen extending from a first opening at a proximal portion of the valve stem to a second opening at a distal end of the valve stem. A plurality of seals may be positioned relative to the valve stem. The valve stem and seals may be configured so that a fluid entering the inlet is prevented from flowing to the outlet in a first position of the valve stem and relative to the inlet and the outlet. The valve stem and the seals may be configured so that a fluid entering the inlet flows to the outlet in a second position of the valve stem relative to the inlet and the outlet, the second position being more distal than the first position relative to the inlet and the outlet.

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 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.
