Digitally adjustable phrenic nerve stimulator system

A system for electrical ventilation stimulation of a patient, comprising:

• an implantable nerve stimulator including:
• a battery,
• a central processing unit,
• a plurality of hardware peripherals including a first timer, a second timer, a third timer, a digital-to-analog converter, and a direct memory access controller,
• a near field communication memory tag including an adjustable setting, and
• a stimulation circuit electrically coupled to the battery, wherein an output of the stimulation circuit stimulates a phrenic nerve and is controlled by the central processing unit based on the adjustable setting and the plurality of hardware peripherals;
• and
• an external digital programming device having near field communication transmission and a digital interface, wherein the external digital programming device is configured to change the adjustable setting of the implantable nerve stimulator;
• and
• wherein the first timer is used to control pulse timing, the second timer is used to control pulse polarity, the third timer is used to trigger digital-to-analog conversions, the digital-to-analog converter is used to control pulse magnitude, and the direct memory access controller is used to update peripheral memory registers.
