Apparatus and methods enable robust, reliable control for implantable medical devices, including cardiac pacemakers, defibrillators and cardiac resynchronization devices. Integrated circuits in the devices have minimized interfaces, can derive power from the interface signals, and have high voltage and latch-up protection. A device lead has a power generation circuit and a switching circuit using cascaded PMOS transistors for operating with a stable voltage despite fluctuations in the supplied voltage. The lead has control electronics that provide a very low impedance between an electrode and a lead conductor during most of the duration of a pacing pulse, but during a brief initial portion of the pacing pulse, provide a very high impedance to permit charging up a power supply that is local to the control electronics. A method of stabilizing the external impedance and a system for fault detection and fault recovery for an implantable device are also provided.

Embodiments 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. Embodiments of the invention enable the required functionality for accurate long term control of effectors units, even ones present on multiplex carrier configurations, while provide for low power consumption. Aspects of the invention include implantable integrated circuits that have power extraction; energy storage; communication; and device configuration functional blocks, where these functional blocks are all present in a single integrated circuit on an intraluminal-sized support. 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.

Methods and systems for programming a plurality of leads under at least two distinct modalities are provided. The leads may be grouped within satellites and multiple satellites may be configured within a single lead. Each lead includes a power and communications bus providing commands, and information and pulses to the satellites. The leads may be connected to at least two different command and pulse sources, optionally a cardiac pacemaker and/or a cardiac pulse analyzer system. A command may include or be preceded by a wake-up pulse that facilitates identification of a modality applicable to the associated command and data. A command may further optionally include a reference pulse or series of reference pulses, whereby the satellite references data pulses in relation to one or more aspects of the associated reference pulse. A data pulse may deliver two bits of information.

Base station antennas include an externally accessible active antenna module releasably coupled to a recessed segment that is over a chamber in the base station antenna and that is longitudinally and laterally extending along and across a rear of a base station antenna housing. The base station antenna housing has a passive antenna assembly that cooperates with the active antenna module.
