Neural stimulation device, neural stimulation system, and control method

A neural stimulation system, comprising:

• a neural stimulation device and an electrode lead electrically connected to the neural stimulation device;
• wherein the neural stimulation device includes a neural stimulation controller, a pulse generator, and an evoked compound action potential (ECAP) sensor;
• and wherein the neural stimulation controller is configured to:
• instruct the ECAP sensor to turn on while instructing the pulse generator to generate a pulse;
• instruct the ECAP sensor to sense an evoked compound action potential after a sensing delay time has elapsed since instructing the pulse generator to generate the pulse;
• and
• instruct the ECAP sensor to turn off after an ECAP window time has elapsed since instructing the ECAP sensor to sense the evoked compound action potential;
• wherein the sensing delay time is determined based on whether a total duration of the pulse is greater than a predetermined time.

A control method, comprising:

• applied at a neural stimulation device, wherein the neural stimulation device includes a neural stimulation controller, a pulse generator, and an evoked compound action potential (ECAP) sensor, and wherein the neural stimulation controller is configured to:
• instruct the ECAP sensor to turn on while instructing the pulse generator to generate a pulse;
• instruct the ECAP sensor to sense an evoked compound action potential after a sensing delay time has elapsed since instructing the pulse generator to generate the pulse;
• and
• instruct the ECAP sensor to turn off after an ECAP window time has elapsed since instructing the ECAP sensor to sense the evoked compound action potential;
• wherein the sensing delay time is determined based on whether a total duration of the pulse is greater than a predetermined time.
