Abstract: An electrosurgical device includes a distal portion having a first electrode extending distally from an elongated shaft, wherein the first electrode is configured to provide a delivered electrical current to a target treatment site within a patient, and wherein the first electrode defines a first irrigation port configured to release a surgical fluid into the target treatment site; and a second electrode extending distally from the elongated shaft, wherein the second electrode is configured to receive a return electrical current from the target treatment site, and wherein the second electrode defines a second irrigation port configured to release the surgical fluid into the target treatment site; wherein the distal portion of the electrosurgical device defines at least one aspiration port configured to proximally aspirate the surgical fluid from the target treatment site.

Abstract: The technology is generally directed towards wireless power charging of one or more receiver devices within a container that is electromagnetically shielded with respect to the frequency or frequencies used for the wireless charging. A controller determines, via signaling from one or more sensors, that the container is in the electromagnetically shielded state with respect to emitting external radiation at the charging frequency or frequencies. When electromagnetically shielded, the controller controls the output power state of a wireless power transmitter device to charge the one or more receiver devices. The controller can determine when to stop the charging of a receiver device, such as when sufficiently charged. The controller and wireless power transmitter device can charge the one or more receiver devices selectively, e.g., based on which one needs more charge or other criterion. The controller can obtain and externally communicate the state of charge of the receiver device(s).
