1. An implantable device for lead offset determination, the device comprising:
a first electrode lead comprising a first plurality of electrodes;
a second electrode lead comprising a second plurality of electrodes;
a stimulus source for providing a stimulus to be delivered from one or more stimulus electrodes to tissue proximal to one or more stimulus electrodes, the one or more stimulus electrodes being selected from the first plurality of electrodes and the second plurality of electrodes;
measurement circuitry for recording from one or more sense electrodes a signal sensed from the tissue and resulting from the stimulus, the one or more sense electrodes being selected from the first plurality of electrodes and the second plurality of electrodes;
wherein at least one electrode of the first plurality of electrodes serves as either a stimulus electrode or as a sense electrode, and wherein at least one electrode of the second plurality of electrodes serves as either a stimulus electrode or as a sense electrode; and
a processor configured to process the signal from the measurement circuitry in order to produce a measure of a stimulus artefact present in the signal; and
the processor further configured to process the measure of the stimulus artefact to produce a measure of an offset between the first electrode lead and the second electrode lead.
