Abstract

Various aspects of the present invention enable robust, reliable control functionality for effectors present on intraluminal, e.g., vascular leads, as well as other types of implantable devices. Aspects of the invention include implantable integrated circuits that have self-referencing and self-clocking signal encoding, and are capable of bidirectional communication. Also provided by the invention are effector assemblies that include the integrated circuits, as well as implantable medical devices, e.g., pulse generators that include the same, as well as systems and kits thereof and methods of using the same, e.g., in pacing applications, including cardiac resynchronization therapy (CRT) applications.
