1. A system for navigating an elongated body on a surface of a tissue, comprising:
- an internal elongated body comprising a distal end and a first element positioned at or near the distal end of the internal elongated body, the internal elongated body devoid of an ablation contact; and
an external elongated body comprising a distal end and a second element and an ablation contact positioned at or near the distal end of the external elongated body, the ablation contact being configured to remove or destroy tissue, wherein the first element and the second element are magnetically attracted to each other;
wherein when a portion of the external elongated body is positioned on or adjacent to a first surface of a tissue and when a portion of the internal elongated body is positioned on or adjacent to an opposing surface of the tissue, manipulation of the internal elongated body directs movement of the external elongated body to a first location to facilitate removal or destruction of tissue at the first surface at a first location; and
wherein the external elongated body is further operable to remove or destroy tissue at the first surface at a second location directed by the internal elongated body without moving the internal elongated body.

15. A system for navigating an elongated body on a surface of a tissue, comprising:
-
an internal elongated body comprising a distal end and a first element positioned at or near the distal end of the internal elongated body, the internal elongated body devoid of an ablation contact; and an external elongated body comprising a distal end and a second element and an ablation contact positioned at or near the distal end of the external elongated body, the ablation contact being configured to remove or destroy tissue, wherein the first element and the second element are magnetically attracted to each other; wherein at least one of the first element and/or the second element comprises a magnet, and wherein the other of the first element and/or the second element comprises a magnetically-attractive non-magnet material if the first element and the second element do not both comprise magnets; wherein the internal elongated body and the external elongated body are each selected from the group consisting of a catheter and a wire; wherein when a portion of the external elongated body is positioned on or adjacent to a first surface of a tissue and when a portion of the internal elongated body is positioned on or adjacent to an opposing surface of the tissue, manipulation of the internal elongated body directs movement of the external elongated body to a first location to facilitate removal or destruction of tissue at the first surface at a first location; and wherein the external elongated body is further operable to remove or destroy tissue at the first surface at a second location and along the first surface between the first location and the second location directed by the internal elongated body without moving the internal elongated body.

16. A method of ablating a tissue, the method comprising the steps of:
-
positioning at least a portion of an internal elongated body adjacent to a first surface of a tissue, the internal elongated body comprising a distal end and a first element positioned at or near the distal end of the internal elongated body, the internal elongated body devoid of an ablation contact; positioning at least a portion of an external elongated body adjacent to an opposing surface of the tissue, the external elongated body comprising a distal end and a second element and an ablation contact positioned at or near the distal end of the external elongated body, the ablation contact being configured to remove or destroy tissue, wherein the first element and the second element are magnetically attracted to each other; manipulating the internal elongated body to direct the ablation contact of the external elongated body to a first location on the first surface of the tissue; first ablating the first location on the first surface of the tissue using the external elongated body; and second ablating a second location on the first surface of the tissue using the external elongated body directed by the internal elongated body without moving the internal elongated body. - View Dependent Claims (17, 18, 19, 20)
