A medical device in one embodiment includes an electrode which is connected to a flexible, tubular, movable member, such as a catheter shaft or an outer sheath, which is slidably extended over a guide wire, flexible shaft, or other tubular member. A displacement mechanism is connected to the movable member, and may be actuated one or more times to displace the movable member in successive, predetermined increments, for creating a linear lesion or for performing diagnostic functions. |
