Neuromodulation Dose Tracking for Controlled Stimulation Therapy
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Current spinal cord stimulation (SCS) treatment paradigms lack effective mechanisms for managing patient self-administration of therapy, leading to potential overuse and reduced effectiveness due to tolerance development and lack of scheduled follow-ups for optimization.
Innovation Solution
Implementing a system that allows clinicians to prescribe a set amount of stimulation, track usage, and provide reminders for follow-up appointments, using external controllers to manage stimulation delivery and inform patients when limits are reached or nearing.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of operation
If patients self-administer stimulation therapy without prescribed limits, then therapy accessibility and convenience are improved, but overuse and tolerance development occur leading to reduced effectiveness
Solution Approach 1:
The system implements feedback by tracking cumulative stimulation dose delivered to the patient and providing real-time information through the external controller. The controller monitors total charge delivered and compares it against prescribed limits, alerting patients when approaching maximum dosage. This feedback mechanism enables patients to self-regulate stimulation usage while maintaining convenience of self-administration, preventing tolerance development and maintaining therapy effectiveness.
2Ease of operation
If continuous stimulation is provided without scheduled follow-ups, then patient convenience is improved, but lack of optimization and potential overuse occur
Solution Approach 1:
The system applies preliminary action by pre-establishing prescribed stimulation limits and scheduling follow-up appointments before the patient begins self-administration. The external controller is programmed with maximum dose parameters and reminder settings, automatically initiating follow-up reminders at predetermined intervals. This preliminary configuration maintains patient convenience while ensuring structured optimization opportunities through scheduled clinician reviews.
3Device complexity
If stimulation dose is not tracked and managed, then device simplicity is maintained, but overuse and reduced effectiveness occur
Solution Approach 1:
The system implements self-service by enabling the external controller to autonomously track cumulative stimulation dose and manage prescribing limits without requiring complex clinical monitoring infrastructure. The controller automatically integrates dose information from each stimulation event, maintains running totals, and enforces prescribed limits. This self-service capability maintains relative device simplicity while ensuring reliable therapy effectiveness through automated dose management and patient education.

AI summary
Methods and systems for providing stimulation therapy are disclosed. Embodiments of the system include an implantable stimulator and an external controller configured to control the implantable stimulator. A clinician can prescribe a set amount of stimulation therapy to a patient. The external controller is programmed with the prescription. As the patient uses the external controller and the stimulator device the external controller tracks the amount of stimulation the patient uses. Once the patient has used all of the prescribed therapy the patient may return to the clinician for a follow-up appointment.
