Abstract:
An improved assembly (10) for steering and orienting a functional element (20) at the distal end of a catheter tube (30) which holds the functional element (20) with its major axis (24) aligned with the axis of the catheter tube (30) for convenient steering to a tissue site (28). The mechanism can also pivot the functional element (20) in response to an external force to orient the major axis (24) of the functional element (20) generally parallel to the plane of the tissue site (28), without bending the catheter tube (30).
