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. At least one support wire is parallel to the lead wires and has a higher strain energy absorption capacity than the lead wires to mechanically strengthen the lead wires against external impact force.

Impact protection for implantable electric lead

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.

A novel implantable electric lead arrangement is described for medical implant systems such as middle ear implants (MEI), cochlear implants (CI) and vestibular implants (VI). An electric lead contains parallel lead wires wound in an elongated helix about a central longitudinal axis. A lead core is fixed and enclosed within the wire helix for providing impact strain relief to the lead wires by resisting radial and/or axial deformation from external impact force.

A cochlear implant electrode is described. A basal electrode lead carries electrical stimulation signals from an implant housing to a cochleostomy opening, and a portion of the electrode lead has a periodically recurring lead shape. An apical electrode array at the cochleostomy end of the electrode lead passes into a cochlea scala and includes electrode contacts for applying the electrical stimulation signals to target neural tissue. A portion of the electrode array has a periodically recurring array shape different from the lead shape.
