Implanted pulse generators with reduced power consumption via signal strength/duration characteristics, and associated systems and methods

A system for providing stimulation therapy to a patient, the system comprising:

• a signal generator programmed to deliver an electrical signal to the patient;
• a processor;
• and
• a memory storing instructions that, when executed by the processor, cause the signal generator to:
• increase a signal delivery parameter of the electrical signal in response to a decrease in an available voltage,
• wherein the increase is based on a correlation between the signal delivery parameter and signal delivery amplitudes, and
• wherein the signal delivery parameter is a pulse width and/or a duty cycle.

A system for providing stimulation therapy to a patient, the system comprising:

• a signal generator programmed to deliver an electrical signal to the patient;
• a processor;
• and
• a memory storing instructions that, when executed by the processor, cause the signal generator to:
• identify, in response to a determination that an available voltage is insufficient to deliver the electrical signal at a target therapy amplitude and a target signal delivery parameter, (a) an updated therapy amplitude that is less than the target therapy amplitude, and (b) an updated signal delivery parameter that is greater than the target signal delivery parameter, wherein the signal delivery parameter includes a pulse width and/or a duty cycle;
• and
• deliver the electrical signal at the updated therapy amplitude and with the updated signal delivery parameter.
