Classification: CPC A | IPC A

Claim 12:
13. The method of claim 12, wherein the target tissue impedance It for a given time t following an initial time period is calculated according to a formula

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