Summary of the Inventive Concept

The inventive concept leverages the core technology of the original Automated Retrievable Hemorrhage Control System to address critical challenges in industrial pipeline ruptures, wind turbine blade damage, environmental oil spills, structural column reinforcement, and ship hull repairs.

Background and Problem Solved

While the original patent focused on controlling catastrophic bleeding in medical settings, this inventive concept expands the technology's reach to tackle pressing issues in diverse industries. In these fields, the ability to quickly and effectively contain and repair damage is crucial to prevent environmental disasters, economic losses, and human harm.

Detailed Description of the Inventive Concept

The new inventive concept involves adapting the stent graft device to address specific challenges in industrial and environmental contexts. For instance, the system for treating industrial pipeline ruptures deploys a stent graft device configured for pipeline deployment, featuring a catheter, stent, and balloon that can be expanded to seal the rupture. Similarly, the method for repairing a damaged wind turbine blade utilizes a stent graft device to seal the damaged area, while the system for containing environmental oil spills leverages the stent graft device to contain the spill.

Novelty and Inventive Step

The new claims introduce novel applications of the stent graft technology, shifting from medical use cases to industrial and environmental contexts. This inventive step lies in the recognition of the technology's potential to address critical challenges beyond its original purpose, thereby expanding its commercial and societal impact.

Alternative Embodiments and Variations

Alternative embodiments may include modifying the stent graft device's materials, dimensions, or deployment mechanisms to better suit specific industrial or environmental applications. Variations could also involve integrating sensors, actuators, or other components to enhance the system's performance, monitoring, and control capabilities.

Potential Commercial Applications and Market

The inventive concept has significant commercial potential across multiple industries, including oil and gas, renewable energy, construction, and maritime. By addressing critical challenges in these fields, the technology can help mitigate environmental disasters, reduce economic losses, and improve public safety.

Field of Art

Biomedical and industrial engineering, focusing on expandable tubular devices for sealing, reinforcing, or repairing structures, with expertise in stent graft technologies, deployment mechanisms, and adaptive material applications

Person of Ordinary Skill (PHOSITA) Profile

A skilled practitioner with advanced engineering degrees, experience in medical device design, materials science, and cross-domain technology adaptation, capable of recognizing fundamental design principles that can be translated across different technical domains

Obviousness Rationale

A PHOSITA would recognize that the fundamental mechanical principles of the stent graft device - expandable tubular structure, balloon deployment mechanism, and adaptive sealing capability - are inherently transferable across different structural repair contexts. The core technological concept of creating a deployable, expandable device to seal or reinforce a damaged structure remains consistent whether applied to human blood vessels or industrial pipelines. The variations presented represent predictable engineering adaptations that leverage the fundamental design principles established in the original medical device patent.
