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. 11,857,434.

Summary of the Inventive Concept

This inventive concept presents a series of direct improvements and enhancements to the original spinal implant and assembly patent, focusing on solving inherent limitations and increasing efficiency, safety, and effectiveness in spinal implantation procedures.

Background and Problem Solved

The original patent described a spinal implant with at least one resilient, elastic or flexible arm adapted to have an arm axis that becomes generally parallel to an axis of a screw that is received in the implant. However, this design may lead to implant slippage, nerve damage, and difficulties in alignment. The new inventive concept addresses these limitations by introducing novel features that enhance stability, reduce implant slippage, and optimize alignment.

Detailed Description of the Inventive Concept

The enhanced spinal implant assembly features a spinal implant with at least one arm having a curved portion adapted to engage with a corresponding curved portion of an adjacent bone, thereby enhancing stability and reducing implant slippage. Additionally, a method for implanting a spinal implant is proposed, comprising the steps of preparing the implant site, inserting the implant, and using a specialized tool to adjust the arm axis of the implant to optimize its alignment with the adjacent bone. Furthermore, a spinal implant assembly with a reinforced structure is introduced to increase its strength and resistance to deformation. The inventive concept also includes a spinal implant with at least one arm having a detachable portion, allowing for easier implantation and reduced risk of nerve damage. Lastly, a system for monitoring the alignment of a spinal implant is proposed, comprising a sensor adapted to detect the position and orientation of the implant and provide real-time feedback to the surgeon.

Novelty and Inventive Step

The new claims introduce a curved arm portion, a specialized tool for arm axis adjustment, a reinforced implant structure, a detachable arm portion, and a real-time monitoring system. These features are novel and non-obvious compared to the original patent, as they provide a more stable, efficient, and safe spinal implantation procedure.

Alternative Embodiments and Variations

Alternative embodiments of the inventive concept may include varying the curvature of the arm portion, using different materials for the reinforced structure, or integrating the monitoring system with existing surgical tools. Variations may also include adapting the implant design for different types of spinal procedures or patient populations.

Potential Commercial Applications and Market

The enhanced spinal implant assembly has significant commercial potential in the medical device industry, particularly in the spinal implant market. The inventive concept's focus on improved stability, alignment, and safety may lead to increased adoption rates and market share, as well as potential partnerships with leading medical device companies and research institutions.
