Abstract
A guidable, or steerable, or deflectable catheter is provided that includes a proximal portion and a distal portion for insertion into a body cavity. A selectively deflectable segment having an anisotropic bending stiffness for deflection in individual planes is incorporated into the distal portion of the catheter shaft. The deflectable segment comprises a corrugate structure that provides smooth curvatures of desirable configurations, deflection planarity, and easiness.
