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: An ultrasonic surgical instrument and method of limiting an ultrasonic blade temperature includes adjusting at least one power parameter of the ultrasonic energy in response to reaching a predetermined frequency parameter change threshold in the ultrasonic blade limiting the temperature of the ultrasonic blade to an upper temperature limit. The ultrasonic surgical instrument further includes an end effector having an ultrasonic blade, a jaw, and a controller. The jaw is movably positioned relative to the ultrasonic blade and configured to move between an open position and a closed position. The controller operatively connects to the ultrasonic blade and is configured to measure an ultrasonic frequency of the ultrasonic blade. The controller has a memory including a plurality of predetermined data correlations that correlate changes in measured ultrasonic frequency of the ultrasonic blade to a blade temperature of the ultrasonic blade.

Abstract: The inventive device (10) can be used for tissue coagulation and/or tissue ablation. It comprises at least one electrode (16) that serves for generating a spark or plasma jet and is connectable to an electric source (20) for this purpose. The probe (11) is assigned to a measuring device (24) that emits and/or receives light in the proximity of the electrode (16) and determines the distance of the probe (11) from the tissue (36) and/or the tissue temperature and/or the composition of the influenced tissue (36). Preferably the measuring device (24) is operated synchronized with pulses or pauses of the pulse-pause-modulated radio frequency voltage (UHF) of the electrode (16) in order to simultaneously carry out the desired measurements during the operation of the instrument (11) and to feedback control the operation of the instrument (11) based on the gained measurement results.

Abstract: Systems, methods, and devices allow percutaneous mapping, orientation and/or ablation in bodily cavities or lumens. Such may include a structure that is percutaneously positionable in a cavity, such as an intra-cardiac cavity of a heart. Transducers carried by the structure are responsive to blood flow. For example, the transducers may sense temperature, temperature being related to convective cooling caused by blood flow. A controller discerns positional information or location, based on signals from the transducers. For example, blood flow may be greater and/or faster proximate a port in cardiac tissue than proximate tissue spaced from the port. Position information may allow precise ablation of selected tissue, for example tissue surround a port in the intra-cardiac cavity.
