Abstract
An implantable stimulation device is described which includes a flexible carrier member for implantation adjacent to target neural tissue. Carrier wires are embedded within the carrier member for conducting electrical signals. At least one active interface device also is within the carrier member and includes a hermetically sealed device housing without penetration by any electrical conductor, an active interface element within the device housing, an inductive link arrangement providing an electrical connection between the active interface element and a terminal end of one of the carrier wires, and an outer interface surface adjacent to the target neural tissue that provides a communication link between the adjacent target neural tissue and the active interface element.
