1. A method of ablating a tissue surface, comprising:

  • providing an RF ablation device including, a delivery catheter, a first RF electrode at least partially positioned in a lumen of the delivery catheter, and a second RF electrode positioned at least partially in the first RF electrode, a distal end of the second RF electrode having a distal end that is substantially a groundpad; and

    moving a distal end of the first RF electrode in a direction away from the distal end of the second RF electrode to create an ablation line along a selected tissue site between the second RF electrode distal end and the first electrode distal end.
