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. 11,857,792.

Summary of the Inventive Concept

Improved neuromodulation systems and methods for treating sleep disorders, breathing disorders, and other conditions by stimulating cranial nerves, with enhanced device fixation, real-time signal adjustment, bioactive coatings, and advanced monitoring capabilities.

Background and Problem Solved

The original patent disclosed methods for stimulating cranial nerves to treat various disorders. However, the existing approach has limitations, such as device migration, inadequate signal adjustment, and tissue inflammation. The new inventive concept addresses these limitations by introducing novel device fixation mechanisms, real-time signal adjustment, bioactive coatings, and advanced monitoring capabilities.

Detailed Description of the Inventive Concept

The enhanced system comprises a neuromodulation device housing configured for implantation in a cervical region of a patient, with a secure fixation mechanism to a digastric tendon, reducing migration or dislocation of the device housing. The system also includes a lead coated with a bioactive material that promotes neural tissue growth and reduces tissue inflammation. The method involves applying a neuromodulation signal to a cranial nerve target, with real-time adjustment based on sensed physiologic information about the patient. Additionally, a sensor is configured for implantation in a cervical region to detect changes in cranial nerve activity and transmit the information to an external controller, enabling real-time monitoring and adjustment of neuromodulation therapy. A minimally invasive surgical approach is used for device implantation, reducing patient trauma and recovery time.

Novelty and Inventive Step

The new claims introduce novel features, such as secure device fixation, real-time signal adjustment, bioactive coatings, and advanced monitoring capabilities, which are not present in the original patent. These features provide a significant improvement over the existing approach, enabling more effective and efficient treatment of sleep disorders, breathing disorders, and other conditions.

Alternative Embodiments and Variations

Alternative embodiments of the inventive concept could include variations in device design, such as different shapes or sizes, or alternative materials used for the bioactive coating. Additionally, the system could be adapted for use in different anatomical locations or for treating different conditions.

Potential Commercial Applications and Market

The enhanced neuromodulation system has significant commercial potential in the medical device industry, particularly in the fields of sleep medicine, respiratory medicine, and neurology. The system's advanced features and improved efficacy could lead to increased adoption and market share, with potential applications in hospitals, clinics, and private practices.
