Enhanced Integrated Z and Wallstent System for Venous Disease Treatment

An improved stent system combining the benefits of Z stents and braided stents with advanced features for enhanced performance, safety, and efficiency in treating chronic venous disease.

The original Integrated Z and Wallstent patent has limitations in terms of stent deployment, tissue inflammation, and precise placement. The new inventive concept addresses these limitations by introducing a flexible metal braided suture for attachment, bio-compatible coating for reduced inflammation, and a tapered end section for easy insertion into the iliac-caval junction.

The enhanced Integrated Z and Wallstent system comprises a Z stent cylinder attached to a braided stent via a flexible metal braided suture coated with a bio-compatible material. The system features a tapered end section for easy insertion and a surface treatment to enhance endothelialization. The stent can be deployed using a delivery catheter with a built-in ultrasound transducer for precise placement. The system offers improved flexibility, reduced tissue inflammation, and enhanced endothelialization.

The new claims introduce novel features such as the flexible metal braided suture, bio-compatible coating, tapered end section, and surface treatment for enhanced endothelialization. These features provide a non-obvious improvement over the original patent, offering enhanced performance, safety, and efficiency in treating chronic venous disease.

Alternative embodiments of the inventive concept could include varying the material composition of the flexible metal braided suture, using different surface treatments for endothelialization, or incorporating additional features such as drug-eluting capabilities or sensors for real-time monitoring.

The enhanced Integrated Z and Wallstent system has significant commercial potential in the medical device industry, particularly in the treatment of chronic venous disease. The system's improved performance, safety, and efficiency make it an attractive solution for healthcare providers and patients alike.
