    Abstract: An implantable device and associated is disclosed. The device comprises a set of electrodes spatially separated from one another and all coupled to an implantable pulse generator. The device comprises a processor configured for forming a first pacing vector and a second pacing vector. The pulse generator is configured to deliver first pacing pulses to the first pacing vector and delivering second pacing pulses to the second pacing vector. The pulse generator generates a recharging current for recharging a first coupling capacitor over a first recharge time period and another recharging current for recharging a first coupling capacitor over a second recharging time period. An order of recharging the first and second coupling capacitors is dependent upon one of ventricular pacing mode, left ventricle to right ventricle delay (V-V) pace delay, multiple point LV delay and latest delivered pacing pulses to one of the first and second pacing vectors.

    Abstract: A medical device and associated method control the delivery of a cardiac pacing therapy by selecting first and second pacing sites along a first ventricle of a patient's heart and delivering the pacing therapy by pacing the first ventricle using the first pacing site during the periods of a first ventricular pacing mode and using the second pacing site during periods of a second ventricular pacing mode. In one embodiment, the device determines activation times at multiple sites along a ventricle in response to pacing pulses being delivered to the opposite ventricle. A first pacing site is selected in response to the activation time determination. The device delivers the pacing therapy by pacing the first ventricle using the first pacing site during periods of the first ventricular pacing mode.

    Abstract: The disclosure describes circuits for providing therapy in an implantable medical device. The illustrative circuits include features that provide fault tolerance with graceful degradation as well as switching control methods that reduce component count and improves reliability. Fault detection circuit 130 functions to monitor the components of output circuits (such as hold capacitors 102, or tip capacitors 106) in order to detect any abnormalities associated with the operation of the components. In response to detecting a component abnormally, fault detection circuitry 130 transmits a signal to a controller/timer circuit, with the signal being utilized in one embodiment to reconfigure the coupling of the components in the output circuits such that the component (s) that are determined to exhibit an abnormality are switched out of the output circuits.
