1. A method for ablating a target tissue in a patient's body, the method comprising:
providing a device comprising an ablation catheter comprising an ablation element; and an immobilizer mechanism coupled to the ablation catheter, wherein the immobilizer mechanism is distal to the ablation element, and is configured such that a first portion of the immobilizer mechanism anchors the catheter and a second portion of the immobilizer mechanism axially pulls the ablation element after the first portion of the immobilizer mechanism is anchored to a tissue;
inserting the device into a patient's body
immobilizing the device within the patient's body;
axially pulling, via the immobilizer mechanism, the ablation element to contact to a target tissue while the immobilizer mechanism is engaged; and
ablating a surface of the target tissue.
