Abstract
A method of navigating a catheter to a target location in an anatomical structure of a patient includes inserting a portion of a catheter into the patient. The catheter includes an elongate shaft having a proximal and a distal end, and a loop subassembly coupled to the distal end. The loop subassembly includes a loop coupled to the distal end and positioned parallel to the elongate shaft, and electrodes disposed on the loop. The method includes positioning one of a portion of the loop subassembly and a portion of the distal end of the elongate shaft in contact with a surface of the anatomical structure a distance from the target location, and translating the loop subassembly toward the target location with the one of the portion of the loop subassembly and the portion of the distal end of the elongate shaft in contact with the surface of the anatomical structure.
