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, focusing on increased stability, security, and efficiency in spinal implant procedures.

Background and Problem Solved

The original spinal implant and assembly patent, despite its innovative design, still presents limitations in terms of stability, security, and ease of assembly. The new inventive concept addresses these limitations by introducing novel features and mechanisms that improve the overall performance of the spinal implant system.

Detailed Description of the Inventive Concept

The new inventive concept comprises a range of enhancements, including the incorporation of U-shaped projections and channels, mechanical fastening systems, locking mechanisms, and vibration-dampening materials. These features enable a more secure and stable connection between the implant members, reducing the risk of dislodgement and improving the overall efficacy of the spinal implant procedure. The inventive concept also introduces a resilient arm with a stress-relief mechanism, ensuring a more efficient and reliable engagement with the corresponding receptacle.

Novelty and Inventive Step

The new claims introduce novel features and mechanisms that significantly improve the stability, security, and efficiency of the spinal implant system. The use of U-shaped projections and channels, mechanical fastening systems, and vibration-dampening materials represents a non-obvious and innovative solution to the limitations of the original patent.

Alternative Embodiments and Variations

Alternative embodiments of the inventive concept could include the use of different materials, shapes, or sizes for the U-shaped projections and channels, or the incorporation of additional features such as sensors or actuators to enhance the performance of the spinal implant system. Variations could also include the application of the inventive concept to other types of prosthetic devices or medical implants.

Potential Commercial Applications and Market

The enhanced spinal implant assembly has significant commercial potential in the orthopedic and medical device industries, offering improved stability, security, and efficiency in spinal implant procedures. The target market includes hospitals, clinics, and medical device manufacturers, with potential applications in a range of spinal implant procedures, from minimally invasive surgeries to complex spinal reconstructions.
