IMPACT PROTECTION FOR IMPLANTABLE ELECTRIC LEAD

摘要

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.
