Abstract
An electrode tip assembly for a catheter is bendable under the control of the user. The distal tip portion of the assembly is progressively less resistant to bending than the remaining portions. The variable stiffness is provided by tapering the width or thickness of a bendable spring component or otherwise providing a progressive change in bending characteristics by notching, dimpling or stepping the thickness of the spring.
