Abstract: A contacting device for electrical connections to flexible electrode lines insertable or implantable into a patient body, includes a line coil with a plurality of coradially bundled coil wires, an inner fixing sleeve for a partial bundle of the coil wires, the fixing sleeve has a through-slit running in the axial direction for the partial bundle of the coil wires, and a winding groove running in the peripheral direction for the partial bundle led through, an outer electrode sleeve sitting on the inner fixing sleeve and electrically contacted with the partial bundle, and a strain-resistant fixing between the fixing sleeve and the partial bundle guided through the through-slit via an application of force on the partial bundle by pressing the fixing sleeve onto the line coil to produce plastic deformation and by looping the led-out partial bundle around the fixing sleeve in the winding groove by a minimum looping angle.

Abstract: An electrode connection for an electrode catheter including an electrode, a line for electrical signals configured as a coil having an electrode end connected to the electrode, and a fixation device for the electrode end of the coil on the electrode, wherein the fixation device includes an inner sleeve, on which the electrode end of the coil sits, and a squeeze ring, which acts upon the electrode end of the coil, establishing an electrical contact with the electrode and mechanical clamping on the inner sleeve.

Abstract: An electrode catheter, in particular for cardiac therapy, includes an elongated, tube-type catheter body, a ring electrode before the distal end of the electrode catheter for delivery and/or measurement of an electrical signal, in particular an electrocardio signal, by way of the outer electrode contact surface thereof, and a supply lead for the electrical connection of the ring electrode. The ring electrode is mounted on the catheter body such that it can be displaced relative thereto in the longitudinal axial direction.

Abstract: A conductive coil arrangement, in particular for electrode catheters for cardiac therapy, including a multipolar conductive coil having a plurality of coradially interwoven individual coil wires and a contact zone in which at least one individual coil wire from the conductive coil can be connected to a contact element for electrical contacting. The at least one individual coil wire to be contacted is routed outwardly out of the wire interconnection of the conductive coil with a radial direction component. The remainder of the conductive coil is routed further centrally axially through the contact zone.

Abstract: An electrically active electrode element for an implantable electrode lead, having an electrode, which includes an electrically active electrode surface facing toward the outside, and an elongated electric feed line, which is capable of establishing an electric connection to an electrically active implant at the proximal end thereof, and which is embodied as an electrically conducting cable end-to-end, wherein the cable forms the electrode at the distal end thereof. A related electrode lead having such an electrode element is provided, and a method for the production of said electrode line utilizing the electrode element is also provided.

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.
