Ambulatory repeater for use in automated patient care
First Claim
1. A system for applying an ambulatory repeater to secure information exchange in automated patient care, comprising:
- an implantable medical device implanted into a patient and having a memory, the memory comprising;
a cryptographic key uniquely assigned prior to implant;
sensitive information preencrypted under the cryptographic key; and
physiological measures measured on an ad hoc basis by a sensor;
an ambulatory repeater, comprising;
a storage comprising the cryptographic key; and
a processor comprising;
a permissions module to confirm authorization of an external data processing device against the cryptographic key, anda decryption module to decrypt the sensitive information with the cryptographic key into decrypted information; and
an external data processing device, comprising;
an interrogator to receive the decrypted information and the physiological measures from the ambulatory repeater over a wireless interface contingent upon the authorization confirmation.

Abstract
An ambulatory repeater for use in automated patient care is presented. A local memory store includes a cryptographic key, sensitive information, and physiological measures. The cryptographic key is uniquely assigned to the implantable medical device prior to implant of the implantable medical device into a patient. The sensitive information is preencrypted under the cryptographic key and physiological measures are measured by the implantable medical device. An authentication module is in receipt of the cryptographic key. A permissions module confirms authorization of an external data processing device against the cryptographic key. A decryption module decrypts the sensitive information with the cryptographic key into decrypted information. A processor is operatively coupled to the local memory store. A communications module exchanges the decrypted information and the physiological measures with the external data processing device over a wireless interface contingent upon the authorization confirmation. An internal power supply supplies power to the foregoing components.
