1. A ureteral stent comprising:
a tubular member; and
a retaining end, adapted to be placed inside a kidney or a bladder of a patient, comprising a plurality of loops centered about respective loop axes extending in different directions relative to each other,
wherein the retaining end defines a curved path forming the loops, the curved path extending from a generally linear portion of the tubular member to a terminal end of the retaining end, and
wherein, when viewed looking from a location distal to the terminal end and looking toward the generally linear portion, the retaining end crosses over or under itself only once along the curved path from the generally linear portion of the tubular member to the terminal end of the retaining end.
