Paper Abstract

We have developed a unique electrode catheter which combines a deflectable tip with a high torque shaft. The control handle is at the proximal end of the catheter. The control handle and the electrical connector which extends out the back of it are symmetrical about the catheter axis for optimum control. The tip deflects to the desired curve when a piston at the distal end of the handle is pushed forward by a thumb ring, and straightens again when the piston is pulled back. I will talk today about how we have developed this catheter. Although this may seem far afield from an SPIE subject, remember that any catheter used for transferring electrical or laser energy inside the body must have some rather unique properties. The tip or delivery end of the catheter must be placed and controlled correctly from outside the body two or three feet proximal from the tip. This catheter is used by cardiac electrophysiologists to study the electrical conduction system of the heart. During the past ten years the science of electrophysiology (EP) has seen major advances. But the tools of the trade, the catheters for performing the studies, have not significantly improved. Our deflectable tip catheter is indeed a significant advancement.
