A bi-directional electrode catheter comprising an elongated tubular catheter body, a catheter tip section at the distal end of the catheter body and a control handle at the proximal end of the catheter. The tip section comprises two pair of generally diametrically opposed off-axis lumens. Two pair of puller wires extend from the handle, through the catheter body, and into the off-axis pair of lumens of the tip section, where they are anchored in the tip section at different locations along the length of the tip section. Compression coils extend through the catheter body in surrounding relation to the puller wires. At their proximal ends, the puller wires are attached to movable pistons in the control handle. Each piston is controlled by an operator using a slidable button fixedly attached to each piston. Movement of selected buttons results in deflection of the tip section into a generally planar “U”- or “S”-shaped curve.
