1. A method for retrieving information from an implantable medical device, comprising:
- activating an ambulatory repeater;
securely obtaining a cryptographic key uniquely assigned to an implantable device from the implantable device to the ambulatory repeater;
interrogating the implantable medical device with the ambulatory repeater to access patient health information, wherein the patient health information comprise sensitive information and physiological measures;
securely receiving sensitive information from the implantable medical device with the ambulatory repeater, wherein the sensitive information is preencrypted under the cryptographic key;
non-securely receiving physiological measures retrieved from the implantable medical device via the ambulatory repeater;
interfacing a base repeater with the ambulatory repeater through far field telemetric communication;
opening a secure connection between the ambulatory repeater and the base repeater;
securely exchanging the sensitive information from the ambulatory repeater with the base repeater;
closing the secure connection between the ambulatory repeater and the base repeater; and
transmitting the patient health information from the base repeater to a server.

Abstract
An external data processing device to interface with an ambulatory repeater and method thereof is presented. An external data processing device is interfaced in far field telemetric communication with an ambulatory repeater. The external data processing device receives sensitive information preencrypted prior to implant under a cryptographic key uniquely assigned to an implantable medical device over a secure connection from the ambulatory repeater. Physiological measures retrieved from the implantable medical device by the ambulatory repeater are received by the external data processing device over a non-secure connection.
