  • a core wire having a shaped distal portion with a predetermined non-linear shape;

    a catheter having a lumen proportioned to slidably receive the core wire, the catheter including a proximal section and a distal section, the core wire slidably receivable within the lumen such that when the core wire is advanced so that at least a portion of the shaped portion is within the distal section of the catheter, the catheter is deformed to approximate the non-linear shape of the portion of the shaped portion of the core wire that is within the distal section of the catheter; and

    a pull wire within the catheter, the pull wire slidable to cause deflection of the distal section of the catheter.
