Abstract
A steerable catheter comprising a hollow outer tube, a pair of coaxially aligned inner tubes disposed within a distal end portion of the outer tube, an actuating mechanism disposed at a proximal end of the outer tube, and a pull wire extending through the inner tubes from the distal end portion of the outer tube to the proximal end of the catheter. The actuating means includes a bushing slidable in the axial direction of the outer tube for tensioning the pull wire to thereby bend the distal end portion of the outer tube. A flat wire is disposed within the outer tube and is secured to the outer surface of the inner tubes to limit the direction of bending of the distal end portion. The catheter further includes a plurality of electrodes disposed at the distal end portion and connected by wires to an external monitor.
