Abstract
A multi-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 catheter body may have a central lumen, and four off-axis lumens symmetrically positioned about the central lumen. A puller wire extends from the central handle through each off-axis lumen and is anchored to the tip section at a selected location. Within each off-axis lumen in the catheter body, there is provided a compression coil in surrounding relation to the puller wire. The compression coil is fixedly attached to the catheter body at its distal and proximal ends. At its proximal end, each puller wire is attached to a movable piston in the control handle. Moreover, each piston is controlled by an operator using a slidable button fixedly attached to each piston. Movement of a selected button results in movement of a selected puller wire and deflection of the tip section in the direction that puller wire.
