1. An implantable cochlear lead comprising:
- an insulating carrier adapted for placement in a cochlea; and
first and second stimulation electrodes, each electrode carried by the insulating carrier and bounded by external perimeter edges comprising a jagged edge having an edge length and a smooth edge opposite the jagged edge and having an edge length shorter than the edge length of the jagged edge;
wherein the jagged edge of the second electrode is disposed facing the jagged edge of the first electrode, and the smooth edge of the second electrode is disposed away from the smooth edge of the first electrode.

Abstract
An implantable lead may include an insulating substrate and a first asymmetric electrode formed on the insulating substrate. The first asymmetric electrode may have external perimeter edges defining a boundary between an exposed portion of the first electrode and the insulating substrate, wherein the external perimeter edges of the first electrode have asymmetric edge lengths.
