1. A bi-directional deflectable catheter comprising:

  • an outer tubular member having a proximal end, a distal end and a first lumen;

    an inner tubular member having a proximal end and a distal end, the inner member positioned within the first lumen of the outer member, the inner member and outer member being relatively movable, and a distal region of the inner member extending distally of the distal end of the outer member;

    an elongated column member having a proximal end and a distal end, the column member fixed at the distal end of the inner member and fixed at the distal end of the outer member, wherein the column member is configured to bend in a region between the proximal end and the distal end to form an arc having a first height; and

    a restriction member positioned over the column member and distal region of the inner member to restrict the bend of the column member to less than the first height;

    wherein a distal tip portion of the catheter is deflectable in first and second opposing directions from a longitudinal axis of the catheter.
