Solution Overview

Problem

Current methods for diagnosing and monitoring atherosclerotic plaques lack effective markers to distinguish between stable and unstable plaques, which is crucial for predicting acute ischemic events such as stroke and heart attacks, as the progression of atherosclerosis is not well understood, particularly how inflammation contributes to the transition from asymptomatic to symptomatic lesions.

Innovation Solution

The use of CD36 concentration in body fluids or atherosclerotic plaques as a diagnostic and predictive marker, where increased CD36 levels correlate with the progression of plaques towards symptomatic status, allowing for the differentiation between stable and unstable plaques, and monitoring of plaque progression.

Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Measurement precision

If conventional diagnostic methods are used for atherosclerotic plaques, then general plaque detection is possible, but the ability to distinguish between stable and unstable plaques is insufficient

Engineering Contradiction:
Improveplaque stability differentiationVSAvoiddiagnostic method complexity
Core Design Contradiction:
Measurement precisionVSDevice complexity

Solution Approach 1:

The patent applies parameter changes by measuring CD36 protein concentration levels in body fluids as a quantitative biomarker. Different CD36 concentration ranges correspond to different plaque stability states, enabling differentiation between stable and unstable plaques through a simple concentration threshold comparison rather than complex imaging or histological analysis

Inventive Principle:
Principle #35Parameter changes

Solution Approach 2:

The patent uses CD36 protein as an intermediary biomarker that mediates between the complex pathological processes within atherosclerotic plaques and the external diagnostic system. By measuring CD36 levels in accessible body fluids, the complex internal plaque characteristics are translated into a simple, measurable external parameter that indicates plaque stability

Inventive Principle:
Principle #24Intermediary (Mediator)

2Reliability

If detailed plaque characterization is achieved, then accurate prediction of ischemic events is possible, but the diagnostic process becomes more complex and time-consuming

Engineering Contradiction:
Improveischemic event prediction accuracyVSAvoiddiagnosis time
Core Design Contradiction:
ReliabilityVSLoss of time

Solution Approach 1:

The patent applies preliminary action by measuring CD36 concentrations in body fluids to assess plaque stability before acute ischemic events occur. This advance biomarker measurement allows clinicians to identify patients at high risk and implement preventive measures prior to the actual event, rather than waiting for symptomatic presentation

Inventive Principle:
Principle #10Preliminary action

Solution Approach 2:

The patent uses a single parameter measurement (CD36 concentration) to provide comprehensive plaque stability assessment. This simplifies the diagnostic process from complex multi-parameter imaging or histological evaluation to a single blood test, dramatically reducing diagnosis time while maintaining reliable prediction accuracy

Inventive Principle:
Principle #35Parameter changes
