1. An ablation apparatus comprising:

  • (a) a delivery catheter with a distal section, a distal end, a proximal end, and a lumen extending therebetween, wherein a wire having a distal end and a proximal end is located within the lumen of the delivery catheter;

    (b) a handle attached to the proximal end of said delivery catheter, wherein a push-pull mechanism is located within the handle, and wherein the proximal end of the wire is attached to the push-pull mechanism;

    (c) an electrode deployment means positioned at the proximal end of the wire, wherein the wire comprises a retractable tip section;

    the catheter, handle, wire, and deployment means being adapted to cooperate to house non-deploy and deploy the tip section;

    (d) an electrode mounted on the retractable tip section, wherein the electrode has a front side adapted to contact the tissue when the retractable tip section is deployed; and

    (e) ultrasonically visible markers mounted on the distal catheter tip on the electrode.
