Intravascularly implantable integrated circuits
First Claim
1. An implantable integrated circuit to control an electrode, the implantable integrated circuit comprising:
- a power recovery circuit configured to supply power;
a data/clock recovery circuit configured to derive and recover digital data signal to control the electrode, wherein the data/clock recovery circuit is further configured to implement a sleep state of the data/clock recovery circuit in response to a receipt of a sleep signal;
a command interpretation circuit configured to receive the digital data signal from the data/clock recovery circuit and to map the digital data signals into control commands; and
an electrode control circuit configured to receive the control commands from the command interpretation circuit and to identify and control the electrode based on the control commands.

Abstract
Techniques for controlling one or more modular circuits (“satellites”) that are intended for placement in a subject'"'"'s body. The one or more satellites are controlled by sending signals over a bus that includes first and second conduction paths. Also coupled to the bus in system embodiments is a device such as a pacemaker that provides power and includes control circuitry. Each satellite includes satellite circuitry and one or more effectors that interact with the tissue. The satellite circuitry is coupled to the bus, and thus interfaces the controller to the one or more effectors, which may function as actuators, sensors, or both. The effectors may be electrodes that are used to introduce analog electrical signals (e.g., one or more pacing pulses) into the tissue in the local areas where the electrodes are positioned (e.g., heart muscles) or to sense analog signals (e.g., a propagating depolarization signal) within the tissue.
