Abstract

A communications bridge device communicates between a consumer electronics device, such as a smart telephone, and an implantable medical device. The bridge forwards instructions and data between the consumer electronics device and the implantable medical device. The bridge contains a first transceiver that operates according to a communication protocol operating in the consumer electronics device (such as Bluetooth®), and second transceiver that operates according to a communications technique operating in the implantable medical device (e.g., Frequency Shift Keying). A software application is installed on the consumer electronics device, which provides a user interface for controlling and reading the implantable medical device. The software application is downloadable using standard cellular means. The bridge is preferably small, and easily and discreetly carried by the implantable medical device patient. The bridge is preferably also simple to operate, and may have only a simple user interface, or no user interface at all.

Claims

1. A communication bridge device for communicating with an implantable medical device and a consumer electronics device, comprising:

a housing, wherein the housing is portable for a patient;

first transceiver circuitry coupled to a first antenna in the housing configured for wirelessly receiving communications from the consumer electronics device in accordance with a first communications technique;
