Zusammenfassung:A method and apparatus are disclosed for providing forward fluid delivery through an electrosurgical device, while avoiding coring when energy is delivered to the electrosurgical device. The device has a distal face defining an opening, with the distal face including at least one cutting portion and at least one non-cutting portion. An embodiment of the electrosurgical device for puncturing tissue includes an elongate member defining a lumen for fluid; a distal portion including an electrode and the distal face which defines at least one aperture. The portion of the at least one cutting portion defines a leading portion partially surrounding a circumference of the at least one aperture wherein the outer diameter of the at least one of the distal portion of the electrosurgical device or the electrode decreases towards a distal tip of the electrosurgical device.
