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. 11,857,411.

Summary of the Inventive Concept

The inventive concept applies the expandable pericardial sealing member technology to environmental monitoring and control, enabling reliable and efficient sealing of tubular passages in various devices for detecting and monitoring pollutants, contaminants, and noise levels.

Background and Problem Solved

The original patent relates to implantable, expandable prosthetic devices for heart valve replacement. However, the limitations of this technology lie in its restricted application to the medical field. The new inventive concept addresses this limitation by applying the core technology to an entirely different industry, namely environmental monitoring and control, where reliable sealing of tubular passages is crucial for accurate and efficient detection and monitoring of pollutants, contaminants, and noise levels.

Detailed Description of the Inventive Concept

The inventive concept comprises an expandable pericardial sealing member adapted to seal a tubular passage in various environmental monitoring and control devices, such as pollution monitoring devices, water sampling devices, soil sampling probes, air sampling devices, and noise monitoring devices. The sealing member is designed to be radially collapsible and expandable between a radially collapsed configuration and a radially expanded configuration, allowing for easy insertion and secure sealing of the tubular passage. This enables accurate and efficient detection and monitoring of pollutants, contaminants, and noise levels.

Novelty and Inventive Step

The new claims introduce a novel application of the expandable pericardial sealing member technology to environmental monitoring and control, which is non-obvious compared to the original patent's limited application to medical devices. The inventive concept's ability to seal tubular passages in various devices for detecting and monitoring pollutants, contaminants, and noise levels provides a new and innovative solution for the environmental industry.

Alternative Embodiments and Variations

Alternative embodiments of the inventive concept could include variations in the material composition, size, and shape of the expandable pericardial sealing member to accommodate different environmental monitoring and control devices and applications. Additionally, the sealing member could be integrated with sensors, software, and other technologies to enhance its functionality and accuracy.

Potential Commercial Applications and Market

The inventive concept has significant commercial potential in the environmental industry, where accurate and efficient monitoring and control of pollutants, contaminants, and noise levels are crucial for maintaining public health, safety, and environmental sustainability. The target market includes government agencies, environmental monitoring organizations, and companies involved in pollution control, water treatment, and environmental consulting.

Field of Art

Biomedical engineering and environmental monitoring technologies, focusing on expandable sealing members and tubular passage interfaces across medical and environmental diagnostic systems

Person of Ordinary Skill (PHOSITA) Profile

A skilled practitioner with expertise in materials engineering, device design, and interdisciplinary applications of expandable sealing technologies, capable of translating medical device principles to alternative technical domains

Obviousness Rationale

A PHOSITA would recognize the fundamental structural similarity between the source patent's pericardial sealing member and the PTD's environmental monitoring application, understanding that the core mechanical principles of radially collapsible and expandable configurations are transferable across technical domains. The PTD merely extends the known expandable sealing mechanism to a different contextual application, which represents a predictable variation within the skill of an ordinary practitioner. The technical elements of radial expansion, tubular passage sealing, and tissue-derived material composition remain substantially consistent between the medical and environmental monitoring implementations.
