1. A method of ablation comprising:

  • advancing a catheter carrying a distal tip electrode having a distal facing surface provided with at least one depression formed therein having edges with a small radius of curvature to prevent slippage of the distal facing surface, to a desired location within the body and from a proximal end of the catheter and manipulating the distal facing surface of the tip electrode into contact with body tissue at the desired location; and

    ablating tissue at the desired location by application of electrical energy to the tip electrode while the distal facing surface is located in contact with tissue at the desired location.
