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

A family of automated retrievable hemorrhage control systems tailored for extreme operational environments, including combat zones, high-altitude rescue operations, and mass casualty incidents.

Background and Problem Solved

The original Automated Retrievable Hemorrhage Control System addressed the critical need for controlling catastrophic bleeding from large and medium-sized vessels. However, these systems may not be suitable for high-stakes environments where additional challenges, such as limited access to medical resources, harsh weather conditions, or compromised patient immune systems, exist. The new inventive concept addresses these limitations by providing specialized systems that cater to these unique operational environments.

Detailed Description of the Inventive Concept

The inventive concept encompasses a range of systems, including a portable, battery-powered stent graft device for rapid deployment in combat zones, a stent graft device with an integrated oxygen sensor and supplemental oxygen supply for high-altitude, low-oxygen environments, and a hemorrhage control system with a built-in GPS module and communication module for search and rescue operations. Additionally, the inventive concept includes a stent graft device with an antimicrobial coating for patients with compromised immune systems and a system for controlling bleeding in mass casualty incidents with multiple stent graft devices and a central command center.

Novelty and Inventive Step

The new claims introduce novel features, such as the integration of communication modules, GPS, and oxygen sensors, which enable the systems to operate effectively in extreme environments. The inventive step lies in the adaptation of the original Automated Retrievable Hemorrhage Control System to address the unique challenges of these high-stakes environments.

Alternative Embodiments and Variations

Alternative embodiments of the inventive concept may include variations in the design of the stent graft device, such as adjustable diameters or modular components, to accommodate different patient needs and environmental conditions. Additionally, the systems could be integrated with other medical devices, such as defibrillators or ventilators, to provide comprehensive care in emergency situations.

Potential Commercial Applications and Market

The specialized hemorrhage control systems have significant commercial potential in the medical device industry, particularly in the areas of emergency response, search and rescue, and military medicine. The target markets include government agencies, hospitals, and emergency medical services (EMS) providers.
