Abstract
An electrophysiology catheter assembly having a deflection mechanism rotatably disposed within an inner lumen of the catheter so that deflection of the deflection mechanism within the inner lumen results in a deflection of the distal portion of the catheter. Rotation of the deflection mechanism within the inner lumen of the catheter allows universal deflection of the distal portion of the catheter about its longitudinal axis. The deflection mechanism may be first rotated and then deflected or it may be first deflected and then rotated in a deflected condition. The catheter shaft does not need to be rotated to change the shape of its distal portion.
