Enhanced Stent Graft Device for Improved Fluid Flow
Legal Citation
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.

Section 103 Obviousness Analysis (PHOSITA)
Field of Art
Interventional medical device design, specifically intraluminal stent grafts for vascular and organ treatment, requiring expertise in biomedical engineering, materials science, and minimally invasive surgical techniques
Person of Ordinary Skill (PHOSITA) Profile
A biomedical engineer or medical device designer with advanced degree, 5-10 years experience in vascular implant design, familiar with stent graft geometries, material properties, and fluid dynamics in bodily conduits
Obviousness Rationale
A PHOSITA would recognize that the PTD's self-expanding stent structure and optimized flow channel configurations are logical extensions of the source patent's helical membranous strip design. The modifications represent predictable engineering improvements using known techniques in stent graft technology. The variations address common design challenges in intraluminal device performance by incrementally enhancing fluid flow and structural integrity.
