Implantable cardiac electrode

Implantable cardiac electrode comprising an electrode lead and an electrode tip, wherein the electrode tip comprises a housing and a fixation screw received within the housing, wherein the fixation screw is electrically conductive connected to the electrode lead and serves for fixing the electrode tip within cardiac tissue,

• wherein
• the housing comprises a first element and a second element, wherein the first element has a sleeve-like shape and defines a receiving space for the fixation screw, wherein the second element is at least partially inserted into the receiving space so that the first element overlaps the second element in an overlapping area, wherein the first element and the second element are bonded together in the overlapping area, wherein the first element comprises at least in the overlapping area a first material being transparent for light having a first wavelength, wherein the second element comprises at least in the overlapping area a second material that is absorbing for light having the first wavelength,
• wherein a connecting sleeved is arrange around the electrode lead and the fixation screw is arranged around the connecting sleeve.
