Abstract
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.
Claims35
An apparatus, comprising:
- a variable compliance regulator connected to supply a compliance voltage to a power supply rail, the variable compliance regulator configured to dynamically vary the compliance voltage based on a stimulus waveform;
- and
- a pulse generator configured to provide an output waveform, corresponding to the stimulus waveform, to at least one output for delivery of electrical therapy based on the compliance voltage.
An implantable pulse generation system, 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 according to the shape of the stimulus waveform;
- and
- a stimulation apparatus coupled to the power supply rail, comprising:
- a controller configured to generate a stimulus waveform comprising a non-rectangular pulse shape;
- a pulse generator configured to provide an output waveform, corresponding to the stimulus waveform, to at least one output for delivery of electrical therapy based on the compliance voltage.
