AI Technical Summary
Existing medical devices struggle to maintain consistent electrical stimulation therapy delivery as the distance between electrodes and target tissue changes due to patient movement or lead migration, leading to inconsistent therapy efficacy and potential side effects.
A medical device adjusts stimulation parameters based on evoked compound action potential (ECAP) signals to deliver sub-threshold stimulation therapy, maintaining consistent therapy levels by periodically determining stimulation thresholds and interleaving control and informed pulses to sense ECAPs without patient perception.
The solution ensures consistent therapy delivery by reducing side effects and maintaining therapeutic efficacy despite changes in electrode-tissue distance, providing relief for symptoms like chronic pain without patient perception of stimulation.
