pr1or.art Inc., “Next-Generation Angiographic Examination System,” Published Technical Disclosure No. 24-11857354_0010_PTD, Published October 28, 2025, available at https://archive.pr1or.art/24-11857354_0010_PTD
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. 11,857,354.

Summary of the Inventive Concept

The next-generation angiographic examination system leverages machine learning, artificial intelligence, and advanced imaging modalities to revolutionize vascular interventions, enabling precise, efficient, and personalized treatments.

Background and Problem Solved

The original angiographic examination method (Patent US 7,500,784 B2) relies on traditional X-ray imaging, which has limitations in terms of resolution, accuracy, and patient safety. The new inventive concept addresses these limitations by integrating advanced technologies to provide real-time, high-resolution imaging and personalized treatment planning.

Detailed Description of the Inventive Concept

The next-generation angiographic examination system consists of a machine learning-based image analysis module, a high-resolution optical coherence tomography (OCT) system, and a robotic-assisted catheter navigation module. The system utilizes real-time feedback from fluoroscopy and OCT imaging to enable precise and minimally invasive vascular interventions. Additionally, the system generates personalized, 3D-printed vascular models for pre-operative planning and simulation, using data from a patient's pre-interventional CT or MRI scans.

Novelty and Inventive Step

The new inventive concept introduces a paradigm shift in angiographic examination by integrating machine learning, artificial intelligence, and advanced imaging modalities, which enables real-time, high-resolution imaging and personalized treatment planning. This represents a significant departure from traditional X-ray imaging and constitutes a non-obvious improvement over the original patent.

Alternative Embodiments and Variations

Alternative embodiments of the inventive concept could include the use of other advanced imaging modalities, such as ultrasound or MRI, or the integration of additional machine learning algorithms for improved image analysis and treatment planning. Variations of the system could also be designed for specific vascular interventions, such as stent graft placement or angioplasty.

Potential Commercial Applications and Market

The next-generation angiographic examination system has significant commercial potential in the medical device industry, particularly in the fields of vascular interventions and personalized medicine. The system could be marketed to hospitals, clinics, and medical research institutions, with potential applications in cardiovascular disease treatment, cancer therapy, and neurointerventions.
