1. An implantable device, comprising:
- a host subsystem includinga 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 includinga 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
whereinthe 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.

Abstract
Embodiments of the present invention relate to implantable sensors for obtaining hemodynamic data and/or physiologic data. More specifically, embodiments of the present invention enable additional sensing hardware to be added into implantable devices more quickly and less expensively. Additionally, embodiments of the present invention enable such adding of additional sensing hardware with little or no effect on the conventional functions of the implantable device to which the sensor hardware is being added.
