Filed:

Dec 11, 2006

Appl. No.:

11/636548

Inventors:

David Gallo - Naples FL, US

International Classification:

A61B 18/14

US Classification:

606041000

Abstract:

A high efficiency electrosurgical electrode with an advanced electrically conductive tip and aspiration port, and a method of conducting an electrosurgical procedure with such electrode. The electrosurgical electrode comprises an electrically conductive tip with a central lumen or “chimney” surrounded by a plurality of protuberances. The central lumen or “chimney” is “self-cleaning” and/or “self-clearing” in that any tissue passing through the central lumen that might cause a clog is quickly denatured by the surrounding electrode and aspirated from the ablation site, so that the probe does not require special consideration by the user (for example, replacement due to total loss of suction). The plurality of protuberances have various forms and geometries that define a plurality of recesses and that, in one embodiment, are provided in a “star-shaped” or partial “star-shaped” pattern.

Abstract:

An ablator having an electrode positioned at a distal end is disclosed. The ablator may be configured such that the ablator includes an inner shaft having a plurality of distal slots therein and contained within an outer hollow shaft. The inner shaft may extend distally from a distal end of the outer, hollow shaft. The configuration of the distal end of the ablator may increase the operating efficiency of the ablator by reducing the power requirements.
