Abstract: In accordance with various embodiments, methods for controlling electrical power provided to tissue via a surgical device may comprise providing a drive signal. A power of the drive signal may be proportional to a power provided to the tissue via the surgical device. The methods may also comprise periodically receiving indications of an impedance of the tissue and applying a first composite power curve to the tissue, wherein applying the first composite power curve to the tissue comprises. Applying the first composite power curve to the tissue may comprise modulating a first predetermined number of first composite power curve pulses on the drive signal; and for each of the first composite power curve pulses, determining a pulse power and a pulse width according to a first function of the impedance of the tissue The methods may also comprise applying a second composite power curve to the tissue.

Abstract: In accordance with various embodiments, methods to control electrical power provided to tissue via first and second electrodes may comprise providing a drive signal to the tissue via the first and second electrodes and modulating a power provided to the tissue via the drive signal based on a sensed tissue impedance according to a first power curve. The first power curve may define, for each of a plurality of potential sensed tissue impedances, a first corresponding power. The methods may also comprise monitoring a total energy provided to the tissue via the first and second electrodes. When the total energy reaches a first energy threshold, the methods may comprise determining whether an impedance of the tissue has reached a first impedance threshold.

Abstract: An endoscopic surgical apparatus capable of ligation and division. The apparatus has a frame and a tubular shaft attached to said frame. Also attached to the frame is a handle. The apparatus has ligating means and cutting means. Actuation means are mounted to the apparatus for actuating both the ligating means and the cutting means. The apparatus has a clutch means capable of enabling the actuating means to switch between a first mode for actuating the ligating means and a second mode for actuating the cutting means. The cutting means is preferably an extendable J-hook and blade assembly. The cutting means and ligating means are preferably rotatable with respect to the frame. The ligation and division apparatus may be used to ligate and cut blood vessels or tissue in a mammalian body cavity during a surgical procedure.
