Abstract: 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).

Abstract: 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.

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 electrosurgical coagulating and cutting instrument employing pairs of clamping arms having wrist portions proximal to closing ramps and jaws and configured to close at their wrists first, then their distal tips and lastly, their heels. The instrument includes mechanisms for preventing the advancement of a cutting blade when the jaws are not closed. An actuator for closing the jaws includes an actuator handle and a drive head having teeth formed therein and a pawl mounted in the handle for engaging the teeth, these latter structures forming a ratcheting mechanism. Said mechanism is controllably releaseable.
