Abstract: Implantable lead having an electrode body with a free end and an inner part axially movable or rotatably movable with respect to it and an end on which means of fixation are extendable out of the free end by axially displacing the inner part, the inner periphery of the electrode body having an elastically deformable, peripheral, ring or ring segment-shaped, sealing/resistance element fixed to it. The outer periphery of the inner part having a section whose diameter changes (decreases) in the axial direction; this section passes the sealing/resistance element when the inner part is axially displaced. The inner periphery of the electrode body having a section whose diameter changes (decreases) in the axial direction; this section placed so that the sealing/resistance element passes this section when the inner part is axially displaced, the sealing/resistance element increasingly deformed during axial displacement of the inner part and counteracting movement thereof.

Abstract: An electrode contact for an electrode lead for neurostimulation comprises a contact body including a contact surface for contacting human or animal neural tissue. The electrode contact furthermore comprises an arm section for contacting at least one electrical supply lead, wherein the arm section, originating from the contact body, extends laterally in a first spatial direction which runs parallel to a main extension plane of the contact surface. The arm section includes at least one cut-out for guiding through the at least one electrical supply lead.

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: A guide wire for introducing an implantable electrode line, wherein the electrode line is particular a heart electrode line for intracardial sensing of cardiac actionpotentials and/or for electrical stimulation or defibrillation of the heart, and wherein the guide wire is adapted for interlocking with the electrode line, and wherein the guide wire comprises a deformation, in particular curved, wavy, V-shaped, zig-zag, or trapezoidal, enlarging the effective contact diameter of the guide wire to a value corresponding essentially to the inner diameter of a lumen of the electrode line or greater than this.

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.
