IMPLANTABLE ELECTRODE DEVICE

An implantable electrode device, particularly a cardiological electrode device, comprises an oblong, hose-like electrode body ( 1 ) and a helical screw-in electrode ( 8 ), which is displaceable on the distal end ( 3 ) of the electrode body ( 1 ) between a retracted passive position inside the electrode body ( 1 ) and an extended, active fixing position outside the electrode body ( 1 ), which is displaceable by a rotational movement of its electrode line ( 7 ), with the aid of a spindle-type cam controller ( 13, 13', 13'' ), between the retracted passive position and the extended fixing position. The cam controller ( 13, 13', 13'' ) is formed by a separate cam coil ( 16, 16', 16'' ), which is fixedly mounted in the electrode body ( 1 ) and coaxially to the electrode supply line ( 7 ) and, in addition, by a cam body ( 17, 25 ), which is mounted on the electrode supply line ( 7 ) rotationally fixed thereto and engages in the cam coil ( 16, 16', 16'' ).
