1. A device comprising:
- a lead extending between a proximal end and a distal end, the lead comprising, at its proximal end portion, an electrode element configured for fixing in a first body tissue, the lead further comprising;
an anchoring element disposed between the proximal and the distal end for anchoring the device to a second tissue; and
an elastic element disposed between the anchoring element and the distal end and configured so as to permit the pulling of the distal end away from the anchoring element against the biasing force of the elastic element.

15. An implantable device comprising:
a lead extending between a proximal end and a distal end, the lead comprising, at its proximal end portion, an electrode configured for fixing onto a subject'"'"'s heart or into a cardiac tissue, a distal end of said lead being configured to be inserted through a chest wall and skin from interior to exterior, the lead further comprising;
an anchoring element disposed between the proximal and the distal end for anchoring the device to the patient'"'"'s diaphragm, and an elastic element disposed between the anchoring element and the distal end and configured so as to permit the pulling of the distal end away from the anchoring element against the biasing force of the elastic element.
