This technical disclosure describes improvements that would be readily apparent to a Person Having Ordinary Skill In The Art (PHOSITA) when considered in combination with the foundational architecture disclosed in U.S. Patent No. 11,857,294.

Summary of the Inventive Concept

This inventive concept improves upon existing handheld medical devices for measuring tissue properties by introducing advanced features that enhance accuracy, efficiency, and versatility. The enhancements include adjustable light-guiding cones, thermal management systems, modular interchangeable tips, and real-time data processing.

Background and Problem Solved

The original patent disclosed a handheld medical device for measuring tissue properties, but it had limitations in terms of accuracy, depth-dependent optical artifacts, and thermal fluctuations. This inventive concept addresses these limitations by introducing novel features that improve the device's performance, ease of use, and adaptability to different tissue types and measurement modalities.

Detailed Description of the Inventive Concept

The enhanced medical device features an adjustable light-guiding cone that accommodates varying tissue depths, ensuring accurate measurements. A software module corrects for depth-dependent optical artifacts, and a thermal management system maintains a stable operating temperature. The device also includes a modular, interchangeable tip that allows for easy adaptation to different tissue types or measurement modalities. Additionally, a wireless connectivity module enables real-time data transmission to a cloud-based analytics platform for processing and analysis. The device can be configured for automatic self-calibration, and the image sensor can comprise a photodiode or an array of photodiodes.

Novelty and Inventive Step

The new claims introduce a novel combination of features that improve upon the original patent's limitations. The adjustable light-guiding cone, thermal management system, and modular interchangeable tip are non-obvious enhancements that provide significant advantages in terms of accuracy, efficiency, and versatility. The real-time data processing and wireless connectivity features further differentiate this inventive concept from the original patent.

Alternative Embodiments and Variations

Alternative embodiments of this inventive concept could include variations in the design of the light-guiding cone, thermal management system, or modular interchangeable tip. For example, the light-guiding cone could be replaced with a fiber-optic probe, or the thermal management system could utilize advanced materials with high thermal conductivity. The device could also be integrated with other medical instruments or sensors to provide a more comprehensive diagnostic platform.

Potential Commercial Applications and Market

This inventive concept has significant commercial potential in the medical device industry, particularly in the areas of cardiovascular disease diagnosis, wound care, and tissue engineering. The enhanced device could be marketed to hospitals, clinics, and research institutions, offering a more accurate, efficient, and adaptable solution for measuring tissue properties.
