  • Publication number: 20260088197
    Abstract: One aspect relates to a method for producing a multipolar lead for a medical device. A hollow-cylindrical inner lining is provided having a length. Electrically conductive channels are formed by an insulated conductor with a conductor and an insulating layer of a first thermoplastic having a first melting point. The electrically conductive channels are spirally wound around the inner lining to provide a cable. A second thermoplastic is coaxially extruded having a second melting point around the cable as outer insulation. The insulated cable is cut to provide an insulated lead cable. A plurality of contact openings is created in a distal end. The outer insulation and the insulating layer are removed to contact the conductive channel. Electrodes are provided and contacted with the conductive channels via the contact openings. The first melting point and the second melting point have a temperature difference of greater than or equal to 30°C.

  • Publication number: 20240325729
    Abstract: One aspect refers to a lead for a medical device, including a cable comprising an outer insulation having at least one first opening near a distal end of the cable and an inner lumen. The inner lumen is arranged coaxially to the outer insulation. At least one conducting channel is arranged between the outer insulation and the inner lumen. The at least one conducting channel is formed by at least one insulated conductor. The insulation layer comprises a second opening, which is aligned with the at least one first opening. At least one ring electrode surrounds the cable at a position of the at least one aligned first and second opening of the cable. The at least one ring electrode is selectively connected to the conductor of the at least one insulated conductor via a bendable bridging element extending through the at least one aligned first and second opening.
