Abstract: Improved devices, circuits and methods of operation in implantable stimulus systems. An implantable defibrillator may comprise a charging circuit using a transformer to store and build up energy on an HV capacitor or capacitor stack, with the HV capacitor in turn coupled to an H-bridge output circuit having low and high sides for issuing therapy. A current monitoring circuitry is provided on the low side of the H-Bridge and used to form a feedback loop to control current into a transformer that converts battery voltage to a signal that charges the HV capacitor to control current through the H-bridge.

Abstract: Systems and methods for managing communication strategies between implanted medical devices. Methods include temporal optimization relative to one or more identified conditions in the body. A selected characteristic, such as a signal representative or linked to a biological function, is assessed to determine its likely impact on communication capabilities, and one or more communication strategies may be developed to optimize intra-body communication.

Abstract: An implantable pulse generator includes a device housing containing pulse generator circuitry and a header connected to the device housing. The header includes a core assembly defining first and second lead bore cavities sized for receiving terminal pins of leads, first and second labels, and an outer layer. The first label is printed onto a surface of the core assembly proximate the first lead bore cavity and includes a first color. The second label is printed onto the surface of the core assembly proximate the second lead bore cavity and includes a second color different from the first color. The outer layer is overmolded over the core assembly so as to encapsulate the first and second labels and to allow access to the first and second lead bore cavities.
