A bi-directional endoscope comprising a catheter body having a tubular spring frame attached to and extending axially from the distal end thereof. The spring frame comprises a spring body which includes a tip member positioned on the distal end thereof, and a plurality of relief slots disposed therein for allowing the deflection of the spring frame within a first deflection plane. The relief slots are formed in the spring body in a manner defining first and second longitudinally extending stiffening portions which are oriented substantially diametrically opposite each other therewithin. Extending longitudinally through the catheter body and spring frame is a pair of activation wires which are encased by a pair of support sleeves. The spring frame is deflected by stressing the activation wires by subjecting either of the wires to a tensile force. Stressing the wires as operable to transmit the tensile force from the stressed wire to the tip member thus causing the spring body to deflect in the first deflection plane toward the stressed wire.
