A device for configuring a body insert, such as an electrode lead for a stimulation device, has a wire arrangement adapted to be inserted into the interior of the body insert for stiffening and bending the body insert. The wire arrangement has a tip section which, when the wire arrangement is inserted in the body insert, resides at the distal end thereof. The tip section has a bendable insulating polymer element which contains a number of bending actuators connected in series. The bending actuators are formed by successive silicon sections interconnected by polyimide-filled V-groove joints in thermal communication with a heating element. The operation of the heating element from a regulation unit adapted for access at a proximal end of the body insert controls expansion of the polyimide filling the joints, thereby producing a selected amount of bending at the tip section and the distal end section of the body insert. |
