Patent ID: 7653434

Claim:
An implantable device, comprising: a host subsystem including a host controller; a host sensor circuit configured to sense cardiac signals; and a host power supply to provide power for the host controller and host sensor circuit; a sensor subsystem coupled to the host subsystem, wherein the sensor subsystem is configured to obtain at least one of hemodynamic and physiologic data, the sensor subsystem including a sensor module; a sensor controller to interact with the sensor module, the sensor controller separate from the host controller; and a sensor power supply to provide power for the sensor module and the sensor controller, the sensor power supply separate from the host power supply; a hermetically sealed container defining an interior region within which are located both the host subsystem and the sensor subsystem, wherein the container includes a first container half and a second container half configured to be sealed to one another; and wherein the first container half is designed for the host subsystem; the second container half is designed to allow the sensor subsystem to be placed within the interior region of the container without altering a layout of the host subsystem; and the second container half comprises a sensor window.
