1. A method of performing a medical procedure on tissue adjacent an ostium of an anatomical vessel, comprising: providing a catheter having an elongated flexible catheter body including a proximal shaft portion and a distal shaft portion having a proximal section pre-shaped to form a simple curve having an apex sized to be inserted into the vessel ostium, a medial section pre-shaped to form a complex curve, and a distal section configured to contact the adjacent tissue when the curve apex is inserted within the vessel ostium, the catheter including at least one tracking element carried by the distal shaft portion; inserting the catheter into the vessel with the simple curve inserted into the ostium and the distal section in contact with a first tissue site; and rotating the simple curve within the vessel about the curve apex to place the distal section in contact with a second tissue site.
