Abstract: An electrode head of an implantable electrode line, the electrode head including an elongate housing which has a longitudinal axis. The elongate housing includes at least two housing parts, which are cylinder-segment-shaped at least in portions and are fixedly joined together to form the electrode head along the longitudinal axis.

Abstract: An implantable medical device including at least one elongate electrical line with a first electrical component as a functional conductor, and at least one second electrical component with an electrical length. The first electrical component includes a proximal end and a distal end, wherein the distal side is in electrical contact with tissue or blood. The first electrical component is in electrical contact with the at least one second electrical component, and wherein the electrical length of the at least one second component corresponds to at least a tenth of a wavelength (?/10) of electromagnetic waves in a radiofrequency range.

Abstract: An active fixation cardiac electrode lead having a fixation helix movably placed in a housing at the electrode lead's distal end so as to be extended out of the housing's distal end and retraced into an inner space enclosed by the housing. The housing has a wall and a protrusion formed in the wall that protrudes into the inner space into interspaces between windings of the fixation helix. The protrusion causes an axial movement of the helix when the helix is rotated around its longitudinal axis. The protrusion is an integral part of the housing's wall which is bent or embossed to form the protrusion.

Abstract: A screw-in electrode probe for cardiological application comprises an oblong electrode body (1), a supply line (10) running therein, and an electrode head (3) on the distal end (2). The latter is provided with housing (5), a shaft (6) mounted therein so it is rotatable and axially displaceable, and a corkscrew-like screw-in electrode (4) on the shaft (6). A contact spring in the form of an essentially planar spiral spring (11) is situated between these components, whose leg ends (12, 13) are in sliding contact with the housing (5) or the shaft (6), respectively, while exerting a radially directed spring force (F).

Abstract: An intravascular electrode arrangement 10 includes a first and a second electrode line 12, 14 adapted for placement in blood vessels such as veins or arteries, each having at least one stimulation and/or sensing electrode in the region of the distal end of the respective electrode line, wherein there are longitudinal guides 18, 18?, 18?, 18?? provided externally on the first electrode line 12, 12?, 12?, 12?? for the second electrode line 14.
