Abstract
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.
Claims13
An implantable electric lead arrangement for a medical implant system, the arrangement comprising:
- an implantable electric lead having a desired bending flexibility and containing a plurality of parallel lead wires wound in an elongated helix about a central longitudinal axis;
- and
- i. a lead core fixed and enclosed within the wire helix in a portion of the electric lead without altering the desired bending flexibility of the electric lead and configured for providing impact strain relief to the portion of the electric lead by resisting radial and/or axial deformation from external impact force.
