Abstract
A device for sterilizing human females by transuterine fallopian tube coagulation wherein the substantial increase in impedance of the tissues during coagulation is used to signal for termination of treatment.
Claims6
A device for sterilizing human females by transuterine tube coagulation, comprising:
- means for generating a high frequency voltage;
- flexible catheter probe means having an electrode end portion dimensioned to completely contact the wall area of a fallopian tube for transuterine placement of said electrode end portion thereof into said fallopian tube of a human female, means including said probe means for coupling said voltage from said means for generating to said electrode end portion, thereby delivering high frequency voltage from said generating means to said fallopian tube;
- means for making a common ground connection between said generating means and the human female;
- means responsive to the impedance of the tissues adjacent said electrode end portion for signalling when the substantial increase therein occurs indicative of the substantial completion of the dessication phase of the destruction of said tissues;
- and
- means for interrupting delivery of high frequency voltage to said electrode end portion in response to said signalling thereupon.
