    摘要： The invention discloses a device for collection of tiny charges in the Nano-Coulomb-range and below, comprising at least one capacitor stack build by n capacitors and 2n switches (nϵN), at least one further capacitor outside the capacitor stack as buffer capacity, at least two additional switches and a DC input source. The n capacitors are dedicated to be sequentially charged by the DC input source one after the other, wherein the 2n switches in the capacitor stack couple the n capacitors sequentially to the DC input source. The at least one further capacitor is dedicated to be charged from the n capacitors of the capacitor stack at once. Furthermore, the invention discloses a method for small charge collection, comprising the steps of sequentially charging the n capacitors of the at least one capacitor stack by coupling one capacitor after the other to the DC input source by selectively closing the switches and discharging the n capacitors of the capacitor stack into at least one further capacitor outside the capacitor stack (nϵN). Additionally, the usage of the device or the method according to the invention to collect charges from sources with electrical potentials of a few millivolts is disclosed.

    摘要： For use by an implantable system including a first and second leadless pacemakers (LPs) implanted, respectively, in first and second cardiac chambers, a method comprises storing, within memory of the first LP, a paced activation morphology template corresponding to far-field signal components expected to be present in an EGM sensed by the first LP when a pacing pulse delivered to the second cardiac chamber by the second LP captures the second cardiac chamber. The method also includes the first LP comparing a morphology of a portion of an EGM sensed by the first LP to the paced activation morphology template to determine whether a match therebetween is detected, and determining whether capture of the second cardiac chamber occurred or failed to occur, based on whether the first LP detects a match between the morphology of the portion of the EGM and the paced activation morphology template.

    摘要： A system includes a controller module, which includes a storage device, a controller, a modulator, and one or more antennas. The storage device is stored with parameters defining a stimulation waveform. The controller is configured to generate, based on the stored parameters, an output signal that includes the stimulation waveform, wherein the output signal additionally includes polarity assignments for electrodes in an implantable, passive stimulation device. The modulator modulates a stimulus carrier signal with the output signal to generate a transmission signal. The one or more antennas transmit the transmission signal to the implantable, passive stimulation device such that the implantable, passive stimulation device uses energy in the transmission signal for operation, sets the polarities for the electrodes in the implantable, passive stimulation device based on the encoded polarity assignments, generates electrical pulses using the stimulation waveform, and applies the electrical pulses to excitable tissue.
