Magnetic induction communication system for an implantable medical device

摘要

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.

1. An implantable communication system for an active implantable medical device comprising:
an isolation transformer; a coil coupled to said isolation transformer; a first communication component coupled to said isolation transformer so as to receive power and data from a first external component over a closely coupled magnetic induction (MI) link operating at a first frequency and formed between the coil and the first external component; and a second communication component coupled to said isolation transformer so as to receive data from a second external component over a weakly coupled MI link formed between the coil and the second external component, wherein the weakly coupled MI link operates at a second frequency that is different from the first frequency of the closely coupled MI link.
