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. 11,857,393.

Summary of the Inventive Concept

An innovative internal bone fixation system that enhances bone fusion and reduces the risk of complications, featuring a porous architecture support frame, adjustable design, and surface modification for improved bone growth.

Background and Problem Solved

The original internal bone fixation device patent (BACKGROUND INFORMATION) has limitations in terms of promoting bone growth, reducing the risk of implant rejection, and accommodating varying bone shapes and sizes. The new inventive concept addresses these limitations by introducing a porous architecture support frame, adjustable design, and surface modification to enhance bone fusion and reduce the risk of complications.

Detailed Description of the Inventive Concept

The advanced internal bone fixation system consists of a support frame with a porous architecture designed to promote bone growth and fusion. The support frame is made of a biocompatible material and is shaped to match the shape of the bone regions. The system features an adjustable design, allowing it to fit various bone shapes and sizes. Additionally, the surface of the device is modified to enhance bone growth and fusion. The system can be inserted into a subject's body and adjusted to fit the subject's bone shape, reducing the risk of complications. The porous architecture and surface modification work together to reduce the risk of implant rejection and promote successful bone fusion.

Novelty and Inventive Step

The new claims introduce a porous architecture support frame, adjustable design, and surface modification, which are not present in the original patent. These features provide a significant improvement over the existing technology, making the new inventive concept novel and non-obvious.

Alternative Embodiments and Variations

Alternative embodiments of the advanced internal bone fixation system could include varying the material used for the support frame, adjusting the level of porosity in the architecture, or incorporating additional features to enhance bone growth and fusion. Variations could also include different shapes and sizes of the device to accommodate specific bone regions or patient needs.

Potential Commercial Applications and Market

The advanced internal bone fixation system has significant commercial potential in the medical device industry, particularly in the areas of orthopedic and spinal surgery. The system's ability to promote bone fusion and reduce the risk of complications makes it an attractive solution for surgeons and patients. Target markets could include hospitals, clinics, and medical research institutions.
