1. An implantable medical lead comprising:
- at least first and second electrode nodes, the first electrode node comprising a first electrode and the second electrode node comprising a second electrode; and
at least a first wire connecting the first electrode node to the second electrode node, wherein the first wire is electrically connected to the second electrode, the first wire defining a deformable sigma segment whereby the deformable sigma segment of the first wire allows the position of the first and second electrode nodes to change relative to each other.

Abstract
An apparatus and method for relative movement of electrodes in a medical lead are provided. The apparatus includes first and second electrode nodes and a wire connecting the electrode nodes. The wire includes a deformable sigma segment that allows movement of one or both of the first and second electrode nodes relative to each other. The method includes placing the medical lead adjacent tissue. The method further includes moving one of the electrode nodes relative to the other of the electrode nodes.
