Title:
ELECTROSURGERY WITH IMPROVED CONTROL APPARATUS AND METHOD
Document Type and Number:
WIPO Patent Application WO2003063716
Kind Code:
A3
Abstract:
An electrosurgical system includes an electrosurgical generator (32) providing power through an electrode (76), and a laser (25) providing laser energy through an optical fiber. The electrode optical fiber and a source of environmental gas can all be included in a handpiece (36), catheter or other delivery device. In operation, the environmental gas can be released into the vicinity of an operative site and the laser activated to energize atoms along a pathway. Electrosurgical power can then be applied to ionize the items of the atoms of the pathway and create a path of least resistance for an electrosurgical arc. A reduction in the laser power required can be achieved by matching the photon frequency of the lawer with the excitation frequency of the environmental gas. In a laparoscopic procedure, the insufflation gas may be used as the environmental gas.
