Abstract: The present disclosure relates to feedthrough contacts for electronic components of the type used in implantable stimulators such as, for example, cardiac pacemakers, ICDs, CRT-Ds, and/or neurostimulators. A feedthrough conductor includes a metallic electrode, wherein a part of the metallic electrode (2) has a locally enlarged diameter in the region of the passage through an opening (3) in the component housing (4). The ridge (5) formed as a result exerts pressure onto the elastic sealing material (6) disposed around the electrode (2) in a tubular shape, thereby producing a hermetic seal between the electrode surface and the sealing material (6), and between the sealing material (6) and the wall (4) of the housing opening (3). The feedthrough conductor is sealed using an adhesive material (7) on the outer side of the electronic component.
