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. 11,857,788.

Summary of the Inventive Concept

This inventive concept expands the core technology of coordinated trigeminal and vagal nerve stimulation to novel medical applications, including robotic-assisted surgery, bleeding disorders, traumatic brain injury, childbirth, and dialysis, providing a non-invasive, effective, and real-time controlled approach to reduce bleeding and improve patient outcomes.

Background and Problem Solved

The original patent disclosed methods and apparatuses for reducing bleeding via coordinated trigeminal and vagal nerve stimulation, primarily focusing on treating bleeding in a subject. However, the original patent's scope was limited to general bleeding prevention and treatment. This inventive concept addresses the need for more specialized and targeted approaches to bleeding reduction in various medical fields, where uncontrolled bleeding can lead to severe complications and even death.

Detailed Description of the Inventive Concept

The new inventive concept comprises a range of novel applications and use cases, including: (1) reducing post-operative bleeding in robotic-assisted surgery by applying coordinated trigeminal and vagal nerve stimulation during the surgical procedure; (2) controlling bleeding in patients with bleeding disorders using a wearable device and real-time bleeding metrics; (3) treating bleeding-related complications in patients with traumatic brain injury by tailoring the stimulation to the patient's specific injury and bleeding profile; (4) reducing bleeding during childbirth using a vaginal probe and adjusting the stimulation based on the patient's bleeding rate and uterine contraction patterns; and (5) reducing bleeding in patients undergoing dialysis by adjusting the stimulation based on the patient's blood flow rate and fluid removal rate. These applications leverage the core technology's ability to provide real-time controlled bleeding reduction, enhancing patient safety and outcomes in diverse medical contexts.

Novelty and Inventive Step

The new claims introduce novel and non-obvious applications of the coordinated trigeminal and vagal nerve stimulation technology, expanding its scope beyond general bleeding prevention and treatment. The inventive step lies in the specific adaptations and customizations of the technology to address distinct bleeding challenges in various medical fields, demonstrating a significant departure from the original patent's scope and limitations.

Alternative Embodiments and Variations

Alternative embodiments of the inventive concept may include variations in the wearable device design, electrode configurations, and stimulation protocols tailored to specific medical applications. Additionally, the technology could be integrated with other bleeding reduction methods, such as pharmacological interventions or surgical techniques, to create hybrid approaches. These variations would ensure broad conceptual coverage and flexibility in adapting the technology to diverse medical contexts.

Potential Commercial Applications and Market

The inventive concept has significant commercial potential in various medical industries, including surgical robotics, bleeding disorder management, traumatic brain injury treatment, obstetrics, and dialysis. The technology's ability to reduce bleeding and improve patient outcomes could lead to widespread adoption in hospitals, clinics, and medical centers, generating substantial revenue and market growth opportunities.
