Abstract:
An impedance matching circuit may be used to adjust for manufacturing and design tolerances in a surgical instrument. The matching circuit may match the load of a thermal element with the impedance of a power source used to deliver electrical energy to the surgical instrument. The matching circuit may include capacitors, inductors, coaxial cables, varactors, transformers, resistors, and/or combinations thereof. The matching circuit may also comprise a circuit board or flex board layers which may be modified to adjust the impedance of the load.
