1. An implantable medical device system, comprising:
- implantable first and second inductively coupled elements each comprising an inductive coil disposed about a magnetically permeable core;
a first hermetically sealed casing that is at least partially electrically-conductive, wherein the casing is formed from a non-magnetic, low electrical conductive material relative to the core; and
wherein the first element is disposed in the casing, and the second element is disposed external to the casing, and wherein the first and second elements are operable to transfer power across the at least partially conductive casing.

Abstract
A power transfer system for an implanted device, such as an implanted medical device. The implanted device and a power transfer device each include a coil with a magnetically permeable core, so that operatively the coils are magnetically coupled, so as to improve the efficiency of power transfer. The coil resides in an electrically conductive implant case.
