Remote Control of Implantable Device Through Medical Implant Communication Service Band
First Claim
1. A system for detecting and monitoring congestive heart failure in a patient, comprising:
- a body-implantable device comprising a circuit module having surface electrodes on the device arranged and adapted, when the device is implanted, for exposure to tissue in a portion of the patient'"'"'s body generally occupied by the lungs, to perform ongoing measurements of impedance of said body portion;
a radio-frequency transceiver within the body-implantable device in data communication with the circuit module for transmitting the measurements of impedance; and
, a base station comprising a radio-frequency transceiver for receiving data from the body-implantable device and sending instructions to the body-implantable device, and an interface for sending data received from the body-implantable device to a remote location and for receiving instructions from a remote location.

Abstract
A system and method for communicating data and signals through the Medical Implant Communication Service Band using a repeater or base station in the proximity to an implantable device within a patient is disclosed. In a preferred embodiment, the device is capable for early detection and monitoring of congestive heart failure in a patient. Impedance measurements, or other health parameters depending on the type of implantable device or sensor used, are sent using a bi-directional low-power radio operating in the MICS band to a nearby base station which may provide signal processing and analysis. The base station may have an interface to one or more communications networks to connect to a remote location. The system and method of the present invention permits a healthcare professional to monitor an ambulatory patient'"'"'s condition at a remote location and to program the implanted device.

13. A system for monitoring the condition of a patient suffering from congestive heart failure, comprising:
-
a body-implantable medical device having circuitry including plural surface electrodes on the device for measuring impedance between a measurement pair of said electrodes from a predetermined electrical parameter injected in a circuit path between an excitation pair of said electrodes, such that when said device is implanted at a site where said circuit path includes the patient'"'"'s heart and lungs said impedance measurement is indicative of lung congestion;
