<p>A locating device (2) comprising a tip section (4) provided at a distal end of a wire means (6) and a regulation unit (8) provided at a proximal end of said wire means. The locating device is adapted to be inserted into an interior channel within an elongated flexible component, such as a hollow electrode cable, to stiffen the flexible component and bend a distal end section thereof, preferably into a J-shape. The tip section (4) includes a bendable insulating polymer element (20) containing a number of bending actuators (22) connected in series. Each bending actuator comprises silicon plate sections (24) interconnected by polyimide filled V-groove joints (26) provided with heating means (34) allowing the binding angles of said V-groove joints to be controlled by thermal expansion of the polyimide filling (28) thereof by heating this filling (28).</p> |
