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, devices, and methods for monitoring and assessing blood glucose level in a patient are discussed. An exemplary system receives physiologic information from a patient using an ambulatory medical device. The physiologic information is correlated to, and different from, a direct glucose level measurement. The system determines a glucose index indicative of an abnormal blood glucose level using the received physiologic information by the two or more physiologic sensors. The system may use the glucose index to initiate or adjust a therapy, or to trigger a glucose sensor, separate from the two or more physiologic sensors, to directly measure blood glucose concentration.

Abstract: Embodiments herein relate to devices and methods for assessing pulmonary congestion using optical sensing techniques. In an embodiment, a pulmonary congestion monitoring device can be included having a first optical emitter, wherein the first optical emitter can be configured to emit light at a first wavelength, such as at a near-infrared wavelength or an ultraviolet wavelength. The monitoring device can also include a first optical detector configured to detect incident light. The first optical emitter and the first optical detector can be separated by a distance of 1 centimeters (cm) to 10 cm. The monitoring device can be configured so that the light from the first optical emitter propagates through at least one of a lung tissue and an airway tissue. The monitoring device can also be configured to use detected incident light to determine a congestion status of the lung tissue. Other embodiments are also included herein.

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: Systems and methods for monitoring patients with a chronic disease such as heart failure are disclosed. The system may include a physiological sensor circuit to sense physiological signals and generate signal metrics from the physiological signals. The system may include a health status analyzer circuit to use the signal metrics to generate one or more stability indicators of patient health status, such as stability of heart failure status. The system may additionally generate one or more health status indicators indicating patient health status such as heart failure progression. A patient disposition decision may be generated using the health status indicators and the stability indicators to provide an indication of readiness for patient discharge from or a risk of admission to a hospital.
