  • Another subgroup of medical leads are so-called electrodes.
  • These are insulated cables with one or more conductors, which are used for the derivation of electrical signals from the body for diagnostic purposes, or the introduction of electrical signals for therapeutic purposes.
  • conduits are precisely fixed so that they can perform their function permanently. A large part of such lines remains permanently in the brain.
  • the conduit is then routed down the skin from beneath the skin and connected to a unit that controls the delivery and removal of substances or signals.
  • the so-called hydrocephalus shunt system may be mentioned here.
  • the tip of the catheter is placed in one of the fluid-filled spaces of the brain.
  • the other end of the catheter is connected to a pressure relief valve, another catheter connects the pressure relief valve with the abdominal cavity, so that excess brain water is discharged into the abdomen.
  • the so-called deep-brain stimulation unit may be mentioned here.

  • the drill holes for the deep brain stimulation electrodes and for the hydrocephalus shunt valve catheters are typically attached to the forehead of the patient where they will be cosmetically conspicuous if not optimally occluded. Furthermore, if the closure device is applying too much space, the thin skin on the forehead can be irritated and, in the worst case, even punctured.
  • a cosmetically unsatisfactory borehole closure which is particularly noticeable on the forehead, and impressed possibly even crimson irritated, creates in such cases, a considerable suffering and reduces the success of the treatment considerably.

If the lead is an electrode, damage to the lead may occur.

  • an opening for the passage of the line is mounted between the insert and the lid.
