Abstract: An insertable cardiac monitor (ICM) with induction-based recharging capabilities and a transmitting coil for recharging the same are disclosed. The length of the monitoring performed by the ICM is extended and the functionality of the ICM enhanced, by including an internal energy harvesting module that allows for charging the ICM at a high speed without burning the patient or overheating components of the ICM. Internally, the energy harvesting module includes at least two overlapping receiving coils that are spaced to be orthogonal to each other and that have a tilt angle of substantially 45°. Such overlapping wire combination allows to minimize mutual inductance of the solenoid coils and increase the rate at which energy can be provided to the energy harvesting module. Further, the rate at which the energy is transmitted from the outside can be increased by defining in a transmitting coil a substantially triangular gap.

Abstract: A circuit with low voltage energy storage for use in generating a defibrillation waveform is described. A charging circuit includes a pulse capacitor that stores defibrillation energy, a high voltage generator circuit that includes a transformer and a rectification circuit through which the pulse capacitor is charged with the defibrillation energy, and a discharge and polarity control circuit electrically connected to the pulse capacitor and switchable to receive the defibrillation energy, which is output as a defibrillation waveform. A low voltage energy supplementing circuit is electrically connected to the pulse capacitor in line with the high voltage generator circuit and stores supplemental defibrillation energy. A microcontroller is adapted to enable the low voltage energy supplementing circuit to modulate the delivery of the stored supplemental energy to the pulse capacitor to augment the defibrillation energy derived from\the initial defibrillation waveform.

Abstract: A subcutaneous insertable cardiac monitor (ICM) for use in performing long term electrocardiographic (ECG) monitoring is disclosed. The length of the monitoring performed by the ICM is extended, potentially for a life time of the patient, and the functionality of the ICM is enhanced, including enhancing the rate at which data can be offloaded from the ICM, by including an internal energy harvesting module in the ICM. The energy harvesting module harvests energy from outside the ICM, and provides the harvested energy for powering the circuitry of the ICM, either directly or by recharging a power cell within the ICM. As the circuitry of the ICM requires a low amount of electrical power, the harvested energy can be sufficient to support the functioning of the ICM even when the electrical power stored on the ICM at the time of implantation runs out.
