Summary of the Inventive Concept

An implantable intraluminal device with improved fluid flow rates and structural integrity, enabling more efficient treatment of bodily conduits and organs.

Background and Problem Solved

The original patent described an implantable intraluminal device, but it had limitations in terms of fluid flow rates and structural integrity. The new inventive concept addresses these limitations by introducing a self-expanding stent structure, reinforced peripheral walls, and optimized flow channel configurations, ensuring improved fluid flow and reduced turbulence.

Detailed Description of the Inventive Concept

The enhanced stent graft device features a self-expanding stent structure that enables a larger diameter, allowing for improved fluid flow rates between the primary conduit and the side branches. The device also includes a reinforced peripheral wall that enhances its structural integrity and reduces the risk of device failure. Additionally, the device features optimized flow channel configurations to minimize turbulence and ensure efficient fluid flow. A modular design allows for multiple interconnected segments, each with a unique flow channel configuration, to optimize fluid flow and reduce turbulence.

Novelty and Inventive Step

The new inventive concept introduces a self-expanding stent structure, reinforced peripheral walls, and optimized flow channel configurations, which are not present in the original patent. These features provide a significant improvement in fluid flow rates and structural integrity, making the device more efficient and reliable.

Alternative Embodiments and Variations

Alternative embodiments of the inventive concept could include different materials or geometries for the stent structure, varying levels of reinforcement for the peripheral walls, and different flow channel configurations for specific bodily conduits or organs. Additionally, the device could be designed for use in different bodily locations, such as the aorta or peripheral arteries.

Potential Commercial Applications and Market

The enhanced stent graft device has significant commercial potential in the medical device industry, particularly in the treatment of cardiovascular diseases. The device could be marketed to hospitals and medical centers, and could be used in conjunction with other medical devices and procedures to provide a comprehensive treatment solution.
