Abstract: Disclosed embodiments include an apparatus, a system and a method for shunting current between first and second electrodes to temporarily reduce current applied through first and second electrodes. In a nonlimiting embodiment, an illustrative apparatus includes first and second electrode couplings configured to electrically engage proximal ends of the first and second electrodes, respectively, the first and second electrodes each having a distal end configured to conduct electrical current generated by a switchable current source therebetween and through an electrically conductive target. A current inrush regulator is configured to temporarily shunt at least a portion of the electrical current generated by the switchable current source to temporarily reduce the electrical current passing between the distal ends of the first and second electrodes through the electrically conductive target.

Abstract: Apparatus and associated methods relate to controlling electrical power of an electrotherapeutic signal that is provided to a biological tissue engaged by an electrosurgical instrument during a medical procedure. Electrical power—a product of a voltage difference across and an electrical current conducted by the engaged biological tissue—is controlled according to a therapeutic schedule. The electrotherapeutic schedule can be reduced or terminated in response to a termination criterion being met. In some examples, the termination criterion is a current characteristic, such as, for example, a decrease in current conducted by the engaged biological tissue. In some examples, the termination criterion is a biological tissue resistance characteristic, such as, for example, an increase in the biological tissue resistance that exceeds a predetermined delta resistance value.

Abstract: Systems, devices, and methods for delivering laser energy directed toward target tissue using a spectroscopic feedback. An exemplary laser feedback control system comprises a feedback analyzer to receive a signal from a target tissue using a spectroscopic sensor, and a laser controller to determine whether the received signal generally equals a first preset. If the received signal meets the first preset, the laser controller can send a control signal to a laser system to change from a first state to a second state of the first laser system. The laser system can deliver laser energy via an optical fiber towards the target tissue.
