    摘要： Systems and methods for forming a lesion on an endocardial tissue of a patient's heart involve placing an ablation assembly inside of the heart and adjacent to the endocardial tissue, and placing a guiding assembly outside of the heart. An ablation assembly includes an ablation element and a first attraction element, and a guiding assembly includes a second attraction element. First and second attraction elements can be attracted via magnetism. Techniques involve forming an ablation on the cardiac tissue of a patient's heart with an ablation element of the ablation assembly. Optionally, techniques may include moving the second attraction element of the guiding assembly relative to the patient's heart, so as to effect a corresponding movement of the ablation element of the ablation assembly.

    摘要： A medical probe includes an elongate member having a proximal end and a distal end, an ablative element mounted to the distal end of the elongate member, and a cage assembly mounted to the distal end of the elongate member, the cage assembly at least partially covers the ablative element. A method of treating tissue in a body includes inserting an ablative element in the body, placing the ablative element adjacent the tissue, and maintaining a distance between the ablative element and the tissue using a protective catheter element that circumscribes at least a portion of the ablative element.
