This technical disclosure describes improvements that would be readily apparent to a Person Having Ordinary Skill In The Art (PHOSITA) when considered in combination with the foundational architecture disclosed in U.S. Patent No. 11,857,442.

Summary of the Inventive Concept

This inventive concept expands the application of bifurcation treatment technology to new industries, including piping networks, wind turbines, tree care, composite materials, and 3D printing, enabling innovative solutions for complex bifurcation challenges.

Background and Problem Solved

The original patent disclosed a system and method for treating bifurcated vessels in the medical field. However, the limitations of this patent lie in its restricted application to medical devices. The new inventive concept addresses this limitation by adapting the core technology to tackle bifurcation challenges in diverse industries, providing a comprehensive solution for treating bifurcations in various contexts.

Detailed Description of the Inventive Concept

The new inventive concept comprises a system and method for treating bifurcations in various industries. In the piping network industry, the system includes a first delivery catheter and a second delivery catheter, each comprising an elongate shaft, an expandable member, and a stent disposed over the expandable member. The stent is configured to at least partially cover a portion of a side branch pipe as well as a portion of a main branch pipe. In the wind turbine industry, the system includes a first delivery catheter and a second delivery catheter, each comprising an elongate shaft, an expandable member, and a sensor disposed over the expandable member. The sensor is configured to detect defects in the blade at the bifurcation. Similarly, the system can be adapted for tree care, composite materials, and 3D printing applications, providing a versatile solution for treating bifurcations.

Novelty and Inventive Step

The new inventive concept's novelty lies in its adaptation of the original bifurcation treatment technology to diverse industries, providing a non-obvious solution to complex bifurcation challenges. The inventive step resides in the recognition of the applicability of the core technology to various fields, resulting in a comprehensive and innovative solution.

Alternative Embodiments and Variations

Alternative embodiments of the inventive concept could include varying the material composition of the stent, sensor, or patch, or modifying the expandable member's design to accommodate specific industry requirements. Additionally, the system could be adapted for use in other industries, such as aerospace or construction, further expanding its applicability.

Potential Commercial Applications and Market

The new inventive concept has significant commercial potential in various industries, including piping networks, wind turbines, tree care, composite materials, and 3D printing. The market for bifurcation treatment systems in these industries is substantial, with potential applications in pipeline maintenance, wind turbine blade inspection, tree preservation, composite material reinforcement, and 3D printed structure enhancement.
