摘要:
A method and apparatus are disclosed for providing forward fluid delivery through an energy delivery device, while avoiding coring when energy is delivered to the energy delivery device. The device has a distal face defining an opening, with the distal face including at least one electrically exposed portion and at least one electrically insulated portion. An embodiment of the energy delivery device includes an elongate member defining a lumen structured to receive a fluid and a distal face defining an aperture in communication with the lumen, the distal face including an electrically exposed conductive portion and an electrically insulated portion, where the electrically exposed conductive portion is configured such that energy delivered by the electrically exposed conductive portion, while the energy delivery device is advanced into a tissue, punctures the tissue without the tissue substantially occluding the lumen and without creating embolic particles.
