This invention describes a universal device designed to communicate with various types of implantable medical devices (IMDs) from different manufacturers. It works by receiving a signal from an IMD, identifying its specific communication method, and then configuring itself using a digital signal processing (DSP) circuit to talk back to that particular device. The claims specify it includes an antenna, receiver, and transmitter, and is designed to conserve battery life.
Why it matters: Filed before modern software-defined radio and advanced DSPs made multi-protocol medical device communication more feasible and power-efficient. Security for medical devices has also become a critical, evolving field since 2003.
