In Vivo Reflectance Confocal Microscopy for Meissner's Corpuscle Imaging
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Current methods for assessing Meissner's corpuscle density in skin are invasive, painful, and not suitable for serial monitoring, limiting their use in diagnosing and monitoring sensory neuropathies.
Innovation Solution
In vivo reflectance confocal microscopy (RCM) is used to visualize and quantify Meissner's corpuscles in human skin, providing a non-invasive and painless means to assess their density, which can be applied for diagnosing and monitoring sensory neuropathies and other peripheral nervous system disorders.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Measurement precision
If skin biopsy is used to assess Meissner's corpuscle density, then measurement precision is improved, but ease of operation deteriorates due to invasiveness and pain
Solution Approach 1:
The patent replaces the mechanical biopsy procedure with an optical imaging system (confocal microscopy). Instead of physically removing and processing skin tissue, the system uses light to non-invasively image Meissner's corpuscles in living skin, eliminating the need for surgical intervention while maintaining diagnostic capability.
Solution Approach 2:
The patent creates an optical copy or image of the Meissner's corpuscles through confocal microscopy. Rather than physically extracting and examining the actual tissue structures, the system generates detailed visual representations that allow measurement and assessment without physical intervention.
2Reliability
If skin biopsy is used for MC density assessment, then reliability is improved, but loss of time increases due to complex processing requirements
Solution Approach 1:
The optical confocal microscopy system replaces the time-consuming mechanical and chemical processing steps of biopsy analysis. The system directly images living tissue in real-time, eliminating hours of laboratory processing while maintaining diagnostic reliability through high-resolution visualization of neural structures.
Solution Approach 2:
The system performs preliminary imaging and assessment on living skin before any invasive procedures would be needed. By establishing baseline measurements through non-invasive confocal microscopy, the need for subsequent biopsy processing is reduced or eliminated, saving significant time in the diagnostic workflow.
3Measurement precision
If skin biopsy is used for MC density measurement, then measurement precision is improved, but adaptability deteriorates as it is not suitable for serial monitoring
Solution Approach 1:
The non-invasive optical system replaces the single-use biopsy procedure, enabling repeated measurements over time. Since no tissue is removed, the same skin site can be imaged multiple times to monitor changes in Meissner's corpuscle density, providing longitudinal data for disease progression or treatment response assessment.
Solution Approach 2:
The system transitions from a static, one-time biopsy measurement to a dynamic, repeatable imaging process. The confocal microscopy enables time-series imaging that captures changes in neural structure and density, allowing the system to adapt to monitoring needs across different time points and clinical scenarios.

AI summary
Meissner's Corpuscles (MCs) are touch-pressure sensation receptors in glabrous skin. They are imaged by reflectance confocal microscopy to provide a non-invasive, in vivo quantification of their density or size to allow screening for, diagnosis or monitoring of sensory neuropathy and other peripheral nervous system disorders related to diabetes, HIV, or other conditions.
