摘要：
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 receiving a fluid； a distal face defining at least one aperture； and the distal face including at least one cutting portion and at least one non-cutting portion cooperating to produce an elongated cut in a tissue when electrical energy is delivered to the distal face while avoiding coring of the tissue.
