Appeal No. 96-0879
Application 08/101,228
Yamanashi discloses
a surgical tool comprising:
(a) a radio frequency source means for creating
an electromagnetic field in the vicinity of tissue
to be surgically treated; and
(b) an electromagnetic field focusing probe
means for focusing the radio frequency energy
produced by the radio frequency source means at the
region of the tissue making contact with the tip of
the electromagnetic field focusing probe such that
the tissue being contacted is instantaneously
vaporized, producing simultaneously a cutting and
cauterizing effect [column 1, line 67 through column
2, line 10].
The radio frequency source means includes a signal
generator 10 for producing an oscillating electrical signal of
pre-selected frequency, an amplifier 12 for amplifying the
signal, a meter 16 for monitoring the amplified signal, an
impedance matcher 18 for adjusting the impedance between the
signal generator/amplifier and an inductive applicator, and an
inductive applicator in the form of a solenoid coil 14 for
inducing an electromagnetic field in the vicinity of the
tissue to be surgically treated. These components are
connected to one another as shown in Figure 1.
The electromagnetic field focusing probe means consists
