Abstract
Abstract Deflection mechanisms are disclosed that are positionable to deflecting portions of a flexible body, such as a catheter, in more than one direction in a single plane, as well as in more than one plane. The invention allows a distal portion of a catheter to be deflected more than 360 degrees to provide a loop.
