Summary of the Inventive Concept

An improved balloon expandable endoprosthesis with enhanced navigation and sensing capabilities for more effective and safer treatment of vasculature diseases.

Background and Problem Solved

The original balloon expandable endoprosthesis patent has limitations in navigating tortuous vasculature and controlling balloon inflation, which can lead to vessel damage. The new inventive concept addresses these limitations by introducing an improved balloon assembly with reduced profile and enhanced flexibility, a pressure-sensing mechanism for controlled balloon inflation, and an integrated sensor system for real-time monitoring of vessel wall pressure, flow rate, and temperature.

Detailed Description of the Inventive Concept

The enhanced balloon expandable endoprosthesis features an improved balloon assembly with a reduced profile, enabling easier navigation through tortuous vasculature. The system includes a delivery device with a pressure-sensing mechanism to monitor and control balloon inflation, reducing the risk of vessel damage. Additionally, the endoprosthesis incorporates a novel stent-graft architecture with alternating ringed stent elements of varying diameters to accommodate different vessel sizes and shapes. The system also enables customization to a patient's specific vasculature using imaging data to create a patient-specific model of the vessel and optimize the endoprosthesis design accordingly. Furthermore, the endoprosthesis integrates a sensor system for real-time monitoring of vessel wall pressure, flow rate, and temperature, enabling more precise and effective treatment.

Novelty and Inventive Step

The new inventive concept introduces several novel and non-obvious features compared to the original patent, including the improved balloon assembly, pressure-sensing mechanism, novel stent-graft architecture, customization method, and integrated sensor system. These advancements provide significant improvements in navigation, safety, and treatment efficacy.

Alternative Embodiments and Variations

Alternative embodiments of the inventive concept could include varying the material composition of the balloon assembly, incorporating additional sensors or monitoring systems, or modifying the stent-graft architecture to accommodate different vessel types or sizes.

Potential Commercial Applications and Market

The enhanced balloon expandable endoprosthesis has significant commercial potential in the medical device industry, particularly in the treatment of vascular diseases such as atherosclerosis, aneurysms, and stenosis. The target market includes hospitals, clinics, and medical research institutions.
