First Claim
Patent Images
1. A communication system for an active implantable medical device comprising:
- an isolation transformer;
a coil coupled to said isolation transformer;
first and second communication components each coupled to said isolation transformer such that said first and second communication components are electrically isolated from said coil, and such that said isolation transformer enables said first and second communication components to communicate, via magnetic induction (MI) using said coil, with at least one external component.

Abstract
A communication system for an active implantable medical device. The communication system includes an isolation transformer a coil coupled to the isolation transformer, and first and second communication components each coupled to the isolation transformer such that the first and second communication components are electrically isolated from the coil, and such that the isolation transformer enables the first and second communication components to communicate, via magnetic induction (MI) using the coil, with at least one external component.
