Abstract

An electrosurgical system includes an electrosurgical generator, a power source configured to deliver power to at least one load connected to the generator, a master configured to generate an initial pulse, the initial pulse cooperating with a first floating power supply configured to create an electrical connection between at least one first load and the power source, and a plurality of slaves connected in series to the master, wherein a first slave is configured to generate a subsequent pulse based on the initial pulse, the subsequent pulse cooperating with a second floating power supply configured to create an electrical connection between at least one second load and the power source, the subsequent pulse configured to cause an ensuing slave to generate an additional pulse, the additional pulse cooperating with a corresponding floating power supply configured to create an electrical connection between at least one additional load and the power source.

First claim

What is claimed is:

1. An electrosurgical system, comprising:
an electrosurgical generator adapted to supply electrosurgical energy to tissue;
a power source operably coupled to the electrosurgical generator and configured to deliver power to at least one load connected to the electrosurgical generator;
a master device configured to generate an initial pulse signal, the initial pulse signal electrically cooperating with a first floating power supply configured to create an ele…
