Electrosurgical Device having a distal aperture

摘要

A method and apparatus are disclosed for providing forward fluid delivery through an energy delivery device that avoids coring when it delivers energy to a tissue. 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 includes an electrically exposed conductive portion and an electrically insulated portion. The electrically exposed conductive portion is configured such that the energy it delivers 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.

1. An energy delivery device comprising:
an elongate member defining a lumen for receiving a fluid, a distal face of the elongate member defining an aperture in communication with the lumen, the distal face including at least one electrically exposed conductive portion and at least one electrically insulated portion, the distal face being thereby configured to avoid creation of emboli upon delivery of energy via the electrically exposed conductive portion.
