Claim:
1. A method for RF surgical removal of pathological tissue in hollow organs of a patient, comprising the steps of: providing an RF generator configured to generate an RF current, wherein the RF generator has a first output and an antipolar second output; providing a bipolar loop having first and second mutually insulated loop sections which can be brought electrically in contact with the patient; providing a switchover device operable to switch the RF generator between a bipolar mode and a monopolar mode; operating the assembly in the bipolar mode, in which the first output is connected to the first loop section, and the second output is connected to the second loop section such that the RF current flows through the first output and the first loop section, through the patient, and through the second loop section to the second output; operating the assembly in the monopolar mode, in which the first output is connected to at least one of the first loop section and the second loop section; and the second output is connected to a neutral electrode which is configured to be attached to the patient, such that the current flows through the first output and the at least one of the first loop section and the second loop section, through the patient, and out the neutral electrode to the second output; and switching the operation of the RF generator between the bipolar and the monopolar mode at least temporarily.
