摘要： An electrosurgical instrument includes a conductive element in the form of a needle that is surrounded by an insulation layer except at a conductor tip portion of the conductive element. The conductor tip portion and insulation layer each have unique geometric shapes and composition of the parts to reduce or eliminate the production of smoke and eschar and reduce tissue damage. The electrosurgical needle electrode is configured to concentrate the flow of electrosurgical at the tip region.

摘要： An electrosurgical electrode having a distal end for transferring the energy to the tissue and a thermal reservoir spaced apart from the distal end. The materials and shape of the electrode promote the flow of heat away from the distal tip so as to reduce the temperature of the tip during electrosurgery, to reduce tissue damage and to prevent the tissue from sticking to the electrode tip. The electrode is composed of a bio-compatible and highly thermally conductive metal, such as silver or gold of high purity, or alloy of those two metals. The shape provides a cross-sectional area that is constant or increasing as the distance from the tip increases. The rounded distal end transitions into a cylindrical section which then transitions into the thermal reservoir. The thermal reservoir is also cylindrical, having a cross-sectional area that is larger than the cross-sectional area of the first cylindrical section.

摘要： A coating and devices using the coating are provided. The coating is applied in liquid form and dried or otherwise cured to form a durable adherent coating resistant to high temperatures and having optional hydrophobic properties. The coating formulation contains an aqueous formulation of silica, one or more fillers, and sufficient base, (e.g., potassium hydroxide), to have a pH exceeding about 10.5 during at least part of the formulation process. The formulation may contain a compound(s) that affects surface free energy, energy to make the cured coating hydrophobic. Such compounds include silanes containing halogens (e.g., fluorine or chlorine) and in particular silanes containing one or more hydrolyzable groups attached to at least one silicon atom and a group containing one or more halogens (e.g., chlorine or fluorine). A medical instrument (e.g., electrosurgical instrument) may be at least partially covered by a coating using the formulation.

摘要： A method for conducting electrosurgery using increased crest factors employs an electrosurgical instrument having at least one conductive element that is surrounded by an insulation layer except at a conductor edge portion of the conductive element. The conductor edge portion and insulation layer each having unique geometric shapes and composition of the parts concentrate the electrosurgical power, reduce or eliminate the production of smoke and eschar and reduce tissue damage.

摘要： An electrosurgical instrument blade includes a body having more than two electrodes with at least two electrodes having alternating current power supplied to them provide a bipolar alternating current configuration and employ a means other than electrode spacing for reducing or preventing accumulation of eschar. The electrodes are separated from each other using electrically insulating materials such that electric current does not flow between at least two of the bipolar alternating current electrodes unless they contact at least one other electrically conductive medium, such as patient tissue. The conductor edge portion and insulation layer each have geometric shapes and composition to reduce or eliminate the production of smoke and eschar and reduce tissue damage. The outer profile of the insulation layer and conductive element are configured to facilitate the flow of electrosurgical decomposition products away from the conductor edge where they are formed.
