Abstract:
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.
