Abstract
A method for controlling a medical device for treating a biological tissue includes controlling the treatment procedure based on the heat capacity of the biological tissue being treated as observed by the medical device. A change in the rate of change of heat capacity from a decreasing rate to an increasing rate or exceeding a maximum threshold value of rate of change of the heat capacity indicates completion, e.g., cutting or sealing. The heat capacity of the biological tissue may be estimated by determining a ratio of energy input to an end-effector of the medical device over a sampling interval to a change in temperature of the biological tissue over that sampling interval. The method may be incorporated into a controller for a medical device for treating a biological tissue.
