Abstract: Techniques for controlling charging of a high voltage therapy energy storage component are provided to reduce any undesirable impact from charging during unusual operating conditions. Unusual operating conditions may be caused by any of a number of external factors, including saturation of charging transformer core, circuit failures, capacitor mismatches, or the like, which may result in an unexpected power supply voltage drop or abnormally high currents through device components. An implantable medical device may comprise a power source, a therapy module that includes at least one energy storage component, and a charging module coupled between the power source and the therapy module. The charging module is configured to obtain a measurement representative of an average power drawn from the power source and to terminate charging of the at least one energy storage component based at least on the measurement representative of an average power drawn from the power source.

Abstract: System, implantable medical device and method for communicating between an implantable medical device and an external communication device. The implantable medical device has a physical connector, a medical module and a communication module. The medical module is configured to at least one of deliver a therapeutic output by way of the physical connector and/or sense data indicative of a physiologic condition of a patient by way of the physical connector. The external communication device is configured to communicate with the communication module by way of the physical connector. In an embodiment, electronic communication may be by way of a differential pair of connectors.

Abstract: This disclosure provides an implantable medical device comprising a power source a therapy module that includes at least one energy storage component, and a charging module coupled between the power source and the therapy module. The charging module is configured to control charging of the at least one energy storage component of the therapy module. The charging module may be further configured to detect a condition indicative of improper charging, to detect a condition indicative of the implantable medical device being subjected to fields generated by an magnetic resonance imaging (MRI) device, and to terminate charging of the at least one energy storage component when both the condition indicative of improper charging and the condition indicative of the implantable medical device being subjected to fields generated by the MRI device are detected.

Abstract: A system with a medical device, an interface device and a communication controller. A medical device has a medical device communication module. The interface device has an interface device communication module and a user interface operatively coupled to the interface device communication module and configured to communicate with a user of the system. The communication controller has a communication controller module configured to communicate with the medical device communication module and with the interface device communication module and an information server operatively coupled to the communication controller module and configured to drive the user interface of the interface device. The system is configured so that a user of the system may communicate with the medical device using the user interface of the interface device with the user interface of the interface being driven by the information server of the communication module.

Abstract: System and method for providing medical information concerning a patient having first patient physiological data and second patient physiological data. The system has a medical device and a handheld device. The medical device is configured to be implanted in the patient and has a sensor configured to obtain the first patient physiological data and a communication module. The handheld device has a communication module, a processor and a user interface. The device communication module is configured to communicate with the medical device communication module, the device communication module being configured to transfer the first patient physiological data to the handheld device via the communication module. The processor is configured to combine the first patient physiological data and the second patient physiological data and generate feedback having a recommended course of action based, at least in part, on the first patient physiological data and the second patient physiological data.
