Abstract
An impact resistant implantable antenna coil assembly comprising a flat antenna coil having a plurality of laterally separated turns of wire encapsulated with a non-orthogonal force absorbing coil reinforcement in a flexible biocompatible polymer and axially anchored with the reinforcement to a feedthrough case. Thus configured, non-orthogonal impact forces applied to the antenna coil assembly are absorbed and lateral components thereof that would otherwise be reflected as tensile forces in the plane of the coil are prevented from forming or from fracturing wire within the antenna coil.
