TL;DR: An electrosurgical instrument is provided for cauterization and/or welding of tissue of varying impedances, thicknesses and vascularity especially in the performance of endoscopic procedures as discussed by the authors.

TL;DR: In this article, an impedance monitoring device is provided for monitoring the electrical impedance of tissue as it is treated with electrosurgical energy, based on a predicted model of tissue impedance and a number of initial impedance readings, the impedance at which tissue treatment is completed is predicted.

TL;DR: A hemostatic surgical instrument is provided for coagulation, cauterization and/or welding of tissue especially in the performance of endoscopic procedures as mentioned in this paper, which compresses the tissue between interfacing surfaces of first and second elements.

TL;DR: In this paper, a motor-driven surgical cutting and fastening instrument consisting of an end effector, an electric motor, and a motor control circuit is used for monitoring a parameter of the electric motor that is indicative of movement of a moveable member of the end-effector.

TL;DR: An electrosurgical instrument is provided for cauterization and/or welding of tissue of varying impedances, thicknesses and vascularity especially in the performance of endoscopic procedures as mentioned in this paper.
