Legal Citation
Summary of the Inventive Concept
A next-generation stent system integrating self-expanding Z stent cylinders with dynamically adjustable braided stents, enabling real-time optimization of venous stenting in iliac-caval junctions.
Background and Problem Solved
The original Integrated Z and Wallstent patent addressed limitations in iliac vein stenting, but the new inventive concept tackles the shortcomings of fixed-diameter stents and rigid mesh densities. This next-generation system adapts to individual patient needs, minimizing vessel trauma and complications.
Detailed Description of the Inventive Concept
The Adaptive Iliac-Caval Junction Stenting System comprises a self-expanding Z stent cylinder with adaptive diameter adjustment, integrated with a braided stent having a dynamically adjustable mesh density. This allows for real-time optimization of stent expansion and minimization of vessel trauma. The system can be deployed using a method that integrates sensor feedback to monitor vessel pressure and flow, enabling precise adjustments during deployment. Additionally, the system can be customized using machine learning algorithms to optimize stent design and deployment based on patient-specific anatomical data.
Novelty and Inventive Step
The new inventive concept introduces adaptive diameter adjustment and dynamically adjustable mesh density, which are not present in the original patent. These features enable real-time optimization of stent deployment, making the system more effective and safer for patients.
Alternative Embodiments and Variations
Alternative embodiments could include variations in the Z stent cylinder's material or geometry, different mesh density adjustment mechanisms, or integration with other sensors or imaging modalities. These variations would ensure broad conceptual coverage and adaptability to different clinical scenarios.
Potential Commercial Applications and Market
The Adaptive Iliac-Caval Junction Stenting System has significant commercial potential in the medical device industry, particularly in the treatment of chronic venous disease. The system's adaptability and real-time optimization capabilities make it an attractive solution for hospitals and clinicians seeking to improve patient outcomes and reduce complications.

Section 103 Obviousness Analysis (PHOSITA)
Field of Art
Interventional Vascular Medical Devices, specifically stent design for venous systems, requiring expertise in materials engineering, medical device design, and vascular anatomy
Person of Ordinary Skill (PHOSITA) Profile
A biomedical engineer or medical device designer with advanced degree, 5-10 years experience in stent development, familiar with materials science, vascular intervention techniques, and adaptive medical technologies
Obviousness Rationale
A PHOSITA would recognize that the adaptive stent system represents predictable variations on the foundational Z stent and braided stent combination disclosed in the source patent. The core structural elements remain consistent, with incremental improvements in deployment mechanisms and sensor integration that would be considered routine design optimization in medical device engineering. The variations represent logical extensions of existing stent technology using standard engineering problem-solving approaches.
