Problem

Conventional pain management systems for chronic pain patients lack effective remote monitoring and adjustment of neuromodulation therapy, leading to delayed clinical evaluations and suboptimal therapy adjustments due to geographic barriers and subjective pain assessments.

Innovation Solution

A patient monitoring system that includes a sensor circuit to sense physiological or functional signals, a controller circuit to generate mobility metrics, and an electrostimulator to deliver neuromodulation therapy, allowing for remote monitoring and adjustment based on mobility metrics and personalized goals, integrating implantable, wearable, and external devices for continuous assessment.

Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Loss of time

If conventional pain management systems are used, then subjective pain assessments are obtained, but remote monitoring and therapy adjustment are delayed due to geographic barriers

Engineering Contradiction:
Improvedelayed clinical evaluationsVSAvoidremote monitoring capability
Core Design Contradiction:
Loss of timeVSEase of operation

Solution Approach 1:

The patent replaces the mechanical system of in-person clinical visits with a wireless electronic monitoring system. Sensors continuously collect mobility data and transmit it wirelessly to remote systems, eliminating the need for physical travel and enabling real-time remote assessment of pain therapy effectiveness.

Inventive Principle:
Principle #28Mechanics substitution (Replace mechanical system)

Solution Approach 2:

The system enables self-service through automated mobility monitoring and threshold-based alert generation. The sensors and processing systems automatically track mobility metrics, compare them against personalized thresholds, and trigger notifications without requiring continuous clinical intervention, allowing the system to serve itself in monitoring and initial assessment.

Inventive Principle:
Principle #25Self-service

2Measurement precision

If subjective pain assessments are used, then patient self-reporting is obtained, but therapy adjustment precision is reduced

Engineering Contradiction:
Improvetherapy adjustment precisionVSAvoidobjective mobility data
Core Design Contradiction:
Measurement precisionVSLoss of information

Solution Approach 1:

The patent introduces an intermediary objective measurement system using sensors to capture mobility data. This intermediary system translates physical mobility into quantifiable metrics that serve as an objective mediator between the patient's actual physiological state and the clinical assessment, reducing reliance on subjective self-reporting.

Inventive Principle:
Principle #24Intermediary (Mediator)

Solution Approach 2:

The system replaces the subjective mechanical process of patient self-reporting with an objective electronic sensing and data processing system. Sensors continuously measure mobility parameters and the system processes this data to generate precise, objective assessments of pain therapy effectiveness.

Inventive Principle:
Principle #28Mechanics substitution (Replace mechanical system)

3Productivity

If continuous mobility monitoring is implemented, then real-time therapy adjustment is enabled, but device complexity increases

Engineering Contradiction:
Improvetherapy adjustment frequencyVSAvoidsystem component quantity
Core Design Contradiction:
ProductivityVSDevice complexity

Solution Approach 1:

The patent implements multi-functionality by using a single integrated system that performs multiple functions: mobility sensing, data processing, threshold comparison, alert generation, and therapy adjustment coordination. This universal system consolidates what would otherwise require multiple separate devices into one cohesive platform.

Inventive Principle:
Principle #6Universality (Multi-functionality)

Solution Approach 2:

The system merges sensing components, processing units, communication modules, and control functions into an integrated monitoring and adjustment system. By combining these previously separate functions into a unified system, the patent reduces overall complexity while maintaining continuous monitoring and real-time adjustment capabilities.

Inventive Principle:
Principle #5Merging (Combining)

AI summary

This document discusses systems, devices, and methods for monitoring and managing patients with chronic pain. A patient monitoring system comprises a sensor circuit to sense a physiological or functional signal indicative of or correlated to patient mobility, an electrostimulator to generate and deliver neuromodulation therapy to the patient, and a controller circuit to generate a mobility metric using the sensed physiological or functional signal. The mobility metric represents respective times spent in different activity intensity levels associated with one or more types of activities during a specific time period. The controller circuit can trend the mobility metric over time and determine a progress toward a personalized mobility goal of the patient, and control the electrostimulator to initiate or adjust the neuromodulation therapy in accordance with the trended mobility metric or the determined progress toward the mobility goal.
