    摘要： An electrosurgery medical device is enhanced with unique solution-assistance, and comprises, in combination, co-operating device jaws including jaw portions for manipulating tissue, and a plurality of solution infusion openings defined and spaced along each of the jaw portions, for receiving electrolytic solution and infusing the solution onto and into tissue to be manipulated, along said jaw portions. As preferred, the device further comprises at least one, and most preferably, many, longitudinal groove(s) along at least one and most preferably, both, of the jaw portions, with the solution infusion openings located in the groove or grooves. The solution is energized with RF energy and contributes to the functions and beneficial effects of the instrument. The solution exits the openings in the grooves at sufficient flow rates to separate substantially all the operative surfaces of the device from tissue, thereby substantially completely preventing adherence between the operative surfaces and tissue. The solution is further energized to a range of energy densities such that tissues to be affected are sealed against flow of blood, lymphatic fluids, air, and other bodily fluids and gases.

    摘要： Apparatuses and methods are disclosed for introducing a conductive fluid and delivering an electrical current to the fluid at a target site in a body lumen. The electrical current is delivered to the site by a conductive electrode through the conductive fluid, causing the tissues in the lumen walls, or peripheral to the lumen walls, to heat and contract. Application of the current can be discontinued when the lumen wall has contracted or been reduced to the desired extent, which will often be complete occlusion. Alternatively, the current can be applied until tissues peripheral to the lumen are effected.
