Apparatus for energy efficient stimulation

摘要

An apparatus is disclosed for providing efficient stimulation. As an example, a variable compliance regulator can be connected to supply a compliance voltage to a power supply rail, which compliance voltage can vary dynamically based on a stimulus waveform. A pulse generator can be configured to provide an output waveform to one or more output based on the stimulus waveform for delivery of electrical therapy.

1. An apparatus, comprising:
a variable compliance regulator connected to supply a compliance voltage to a power supply rail, the variable compliance regulator being configured to dynamically vary the compliance voltage over time to track a waveform shape and amplitude of a time-varying stimulus waveform; and a pulse generator coupled to receive power from the power supply rail and configured to provide an output waveform to at least one output port in response to the stimulus waveform provided to a control input thereof, the output waveform having a waveform shape and amplitude corresponding to the waveform shape and the amplitude of the time-varying stimulus waveform and having energy that varies as a function of the compliance voltage.
