Abstract

An implantable electric lead arrangement for a medical implant system includes an implantable electric lead with parallel lead wires wound in an elongated helix about a central longitudinal axis. A conical shape lead core is fixed and enclosed within the wire helix for providing impact strain relief to the electric lead by resisting radial and/or axial deformation from external impact force. The conical shape of the lead core is configured for a smooth transition between a lead core portion of the electric lead that is protected against external impact force and a non-lead core portion of the electric lead that is unprotected from external impact force.
