1. A surgical device comprising:
a handheld enclosure configured to be maneuverable as a surgical instrument; and a blade extending from said enclosure, said blade for contacting tissue of a patient, said enclosure containing:
a differential amplifier circuit configured to provide an RF signal having a voltage and a current to said blade at a certain frequency and waveform; and
an input comprising a receiving antenna configured to receive a signal from a signal source comprising a transmitting antenna coupled to a pad in electrical contact with tissue of the patient, wherein said received signal contains frequency and amplitude data from said tissue associated with said RF signal and wherein said input is tunable to increase coupling with the signal source in response to changes in the RF signal or in the tissue with which the blade is brought into contact.
