Methods and apparatus for surgical cutting

TLDR
An electrosurgical probe comprises a shaft having an electrode array (12) at its distal end and a connector at its proximal end as mentioned in this paper, which is used to cut or ablate target tissue while heat dissipation through low impedance paths.
Abstract
An electrosurgical probe comprises a shaft having an electrode array (12) at its distal end and a connector at its proximal end. The array (12) includes a plurality of isolated electrode terminals, and an electrosurgical power supply (28) is provided with a multiplicity of independently limited or controlled current sources and a connector. The electrosurgical probe and the power supply may be connected through their respective connectors so that the independent current sources are connected to individual electrode terminals. By applying very high frequency electrical energy to the electrode array, target tissue may be cut or ablated while heat dissipation through low impedance paths, such as blood and normal saline, will be minimized.

Electrosurgical generator and system

TL;DR: In this article, the authors present a controller that can cause the generator to supply a blended output signal alternating constantly between a first output signal across the output connections in which the radio frequency output voltage developed across output connections is limited to at least a first predetermined threshold value for cutting or vaporization of tissue, and a second output signal with a power supply coupled to the output stage for supplying power to output stage.
