Abstract
Official abstract text for this publication.
An electrosurgical energy delivery apparatus includes an energy delivery circuit, a control circuit and an energy-harvesting system with a plurality of energy-harvesting circuits and a voltage regulator that provides a regulated DC voltage to the energy delivery circuit and/or the control circuit. The energy delivery circuit receives an electrosurgical energy signal having a primary frequency and selectively provides the electrosurgical energy signal to an energy delivery element. The control circuit connects to the energy delivery circuit and selectively enables the flow of electrosurgical energy to the energy delivery element. The plurality of energy-harvesting circuits each include an energy-harvesting antenna tuned to a particular frequency, a matched circuit configured to receive an RF signal from the energy-harvesting antenna, rectify the RF signal and generate a DC signal, and an energy storage device that connects to the voltage regulator to receive and store the DC signal.
First claim
Opening claim text (preview).
What is claimed is: 1. An electrosurgical energy delivery apparatus, comprising: an energy delivery circuit configured to receive an electrosurgical energy signal via a transmission line from an electrosurgical energy source; a control circuit powered by the received electrosurgical energy signal and operatively connected to the energy delivery circuit, the control circuit configured to receive a control signal from an electrosurgical energy source and selectively enable a flow…
