Break-away extractable lead

An electrode arrangement comprising:

• an electrode line having an interior and a distal end, wherein the electrode line has closed casing for sealing off the interior of the electrode line and at least one electrically conducting surface region having at least one electrode at the distal end, wherein the electrode line with the electrode has a diameter which is one of a) uniform over its entire length and b) tapering toward the distal end of the electrode line;
• and
• means coupled to the electrode line for fixing the distal end of the electrode line in body tissue, said fixing means being adapted to be separated from the electrode line by forces acting axially within the electrode arrangement such that the interior of the electrode line remains sealed during separation;
• and
• a synthetic resin material in a separation location between the fixing means and the electrode line, the synthetic resin material being plastic when the fixing means are connected to the electrode line.
