Appeal No. 96-0879
Application 08/101,228
The invention relates to “an electroconvergent cautery
system employing forceps or probes which produce sharply
localized heating for cutting, vaporizing tissue and
coagulating blood vessels when brought into contact with the
same” (specification, page 1). Claim 1 is illustrative and
reads as follows:
1. A surgical tool for surgically treating tissue in a
patient, comprising:
a radio frequency power generator for creating an
alternating current of a pre-selected frequency;
said radio frequency generator including an oscillator, a
buffer amplifier and a power amplifier;
said buffer amplifier and said power amplifier being
series connected;
an impedance matching means connected to said power
amplifier for matching the impedance of a probe with the radio
frequency generator;
a watts/ampere meter connected to said impedance matching
means;
a loading and tuning coil connected to said watts/ampere
meter;
a probe for contact with the tissue;
said loading and tuning coil being connected to said
probe,
