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.

Ablator with improved cutting tip

A high efficiency electrosurgical electrode with an advanced electrically conductive tip and advanced design tube, and a method of conducting an electrosurgical procedure with such electrode. The tube design is provided with a swaged one-piece metal tube that fits in small cannulas (as small as a 5.5 mm cannula). The electrode has a scalloped configuration that provides decreased surface area with more edges. The handle is provided with an ergonomic design that utilizes a bend with a cut at the end of the tube (for example, a 30 degree bend with a 15 degree cut).

Ablator with scalloped electrode and swaged tube

A suction flow regulator including an adapter and a grommet fixed inside the adapter for permitting air to access a vacuum flow path according to a vacuum level. The grommet is fixed inside an adapter by a securing mechanism (for example, a compression plate). The grommet may be used with an additional elastomeric element (for example, a smaller grommet) that provides flexibility during vacuum exposure and deflects to expose holes in the grommet under vacuum. Alternatively, the grommet may be a single unit grommet with a cantilever configuration.

Suction flow regulator

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 &#x201c;self-cleaning&#x201d; and/or &#x201c;self-clearing&#x201d; 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 &#x201c;star-shaped&#x201d; or partial &#x201c;star-shaped&#x201d; pattern.
