    Abstract: A multi-dimensional loop tip structure is provided that is capable of navigating through a tortuous body lumen. The multi-dimensional loop tip structure includes two or more loops or partial loops at the distal end of the structure. The structure may alternatively include three or more legs at the distal end of the structure. The loops or legs allow the structure to continuously realign itself to the center of a body lumen that it is being navigated through when encountering impediments therein.
