Abstract
A steerable catheter comprises an elongated catheter body and a tip portion. First and second lumens extend through the catheter body and tip portion. The first lumen is open at the distal end of the catheter. The second lumen is off-axis. A tightly wound coil spring is disposed in the second lumen and extends the length of the catheter body. The coil spring is fixed at the ends of the catheter body. A puller wire is slidably disposed within the coil spring, its distal end extending into and fixed at the distal end of the tip portion. The proximal end of the puller wire is attached to a control handle. Manipulation of the control handle results in deflection of the tip portion without deflection of the catheter body.
