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. 11,857,443.

Summary of the Inventive Concept

An advanced hemorrhage control system featuring real-time blood flow rate monitoring, predictive analytics, and self-healing materials to improve treatment outcomes and reduce mortality rates.

Background and Problem Solved

The original Automated Retrievable Hemorrhage Control System, while effective, had limitations in its ability to provide real-time monitoring and adapt to changing blood flow rates. The new inventive concept addresses these limitations by integrating advanced sensors, data analytics, and self-healing materials to create a more efficient, safer, and more effective system.

Detailed Description of the Inventive Concept

The Enhanced Automated Retrievable Hemorrhage Control System comprises a stent graft device with an adjustable diameter and a balloon equipped with a pressure sensor for real-time monitoring of blood flow rate. The system also includes a data analytics module that predicts hemorrhage risk based on historical blood flow rate data and provides alerts to medical personnel. Additionally, the stent graft device features self-healing materials that seal punctures and tears in response to changes in blood pressure. The system can be deployed through a percutaneous access site using a controlled inflation protocol to minimize vessel trauma.

Novelty and Inventive Step

The new inventive concept introduces several novel features, including real-time blood flow rate monitoring, predictive analytics, and self-healing materials, which collectively provide a significant improvement over the original patent. The combination of these features enables more effective and efficient hemorrhage control, reducing mortality rates and improving treatment outcomes.

Alternative Embodiments and Variations

Alternative embodiments of the inventive concept could include variations in the stent graft design, such as using different materials or geometries, or incorporating additional sensors to monitor other physiological parameters. Other variations could include different deployment methods or user interfaces for real-time monitoring.

Potential Commercial Applications and Market

The Enhanced Automated Retrievable Hemorrhage Control System has significant commercial potential in the medical device industry, particularly in the fields of trauma care, vascular surgery, and emergency medicine. The system's ability to improve treatment outcomes and reduce mortality rates makes it an attractive solution for hospitals and medical centers.
