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, 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) determine an updated therapy amplitude and an updated signal delivery parameter based on pre-established correlations for similarly situated patients, and (b) deliver therapy to the patient using the updated amplitude and signal delivery parameter, wherein the signal delivery parameter includes a pulse width and/or a duty cycle.

A method of establishing a correlation between an amplitude and another signal delivery parameter for a particular patient, the method comprising:

• identifying at least one amplitude/parameter pair that produces a detectable result in the patient;
• and
• comparing the identified amplitude/parameter pair to a plurality of pre-established amplitude/parameter curves generated using data from a pool of other patients to identify a particular amplitude/parameter curve for the patient,
• wherein the signal delivery parameter includes a pulse width and/or a duty cycle.
