Claim 4:
5. The system of claim 4, wherein the target impedance of the endometrial lining tissue for the duration of the endometrial lining ablation procedure is determined according to a formula,

It=Imax−((Imax−Io))*S),, where
It is a target tissue impedance for a given time t during the endometrial lining ablation procedure,
Imax is a target maximum impedance of the endometrial lining tissue,
Io is a projected impedance of the endometrial lining tissue for the given time t during the endometrial lining ablation procedure derived from a function approximating the preexisting endometrial lining tissue ablation impedance curve, and
S is a scaling factor equal to (Imax−Imeas)/(Imax−Iio), where Imeas is the measured initial impedance of the endometrial lining tissue, and Iio is a projected initial impedance of the endometrial lining tissue derived from the function approximating the preexisting endometrial lining tissue ablation impedance curve.
