Tetrod

Tetrod

Essentially a standard steel tube electrode. The drainage points are arranged in two rows, 50 microns apart, in groups of four.

The electrode is suitable for piercing the dura.

Electrode materials:

• Steel needle: thin-walled stainless steel tube (ferromagnetic material!)

• Lead points: platinum-iridium wire

• Synthetic resin binder: implant quality synthetic resin

• Connector: Precidip 26-pin socket (for electrical and liquid connection, see connectors)
