Abstract
The present invention relates to a medical device (2) for electrical stimulation. The device comprising an implantable elongated lead system (20) having a distal end (21) and a proximal end (22), the lead system comprises one or more electrical conductors (23) for connection to one or more electrodes (24). The one or more electrical conductors are wound along a length axis (25) of the lead system with a plurality of windings, and wherein the density of windings is non-uniformly distributed along the length axis. In an embodiment, the medical device is in the form of a deep brain stimulation (DBS) device.
