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. 11,857,429.

Summary of the Inventive Concept

A next-generation intervertebral cage apparatus and system that dynamically adjusts its shape in response to changes in the intervertebral disc space, ensuring optimal fit, stability, and fusion.

Background and Problem Solved

Current intervertebral devices are limited by their static design, which can lead to subsidence, implant migration, and inadequate bone fusion. The new inventive concept addresses these limitations by introducing a dynamic, adaptive system that can respond to changes in the intervertebral disc space in real-time.

Detailed Description of the Inventive Concept

The adaptive intervertebral cage apparatus and system comprise a sensor for monitoring the intervertebral disc space and generating a signal indicative of changes, a controller for receiving the signal and adjusting the shape of the intervertebral cage apparatus accordingly, and a plurality of adjustable struts connected to the body of the apparatus. The system can also utilize machine learning algorithms to identify the optimal placement of the intervertebral cage apparatus based on a 3D model of the intervertebral disc space. Additionally, the system can be designed and manufactured using customized 3D models of intervertebral disc spaces, and remotely monitored and adjusted in real-time.

Novelty and Inventive Step

The new claims introduce a paradigm shift in intervertebral cage apparatus design, moving from static to dynamic, adaptive systems. The inventive step lies in the integration of sensors, controllers, and adjustable struts to create a real-time adaptive system, which is not obvious from the original patent.

Alternative Embodiments and Variations

Alternative embodiments may include using different types of sensors, such as pressure or temperature sensors, or incorporating additional features, such as biodegradable materials or tissue-engineered surfaces. Variations may include adapting the system for use in other spinal regions or developing miniaturized versions for minimally invasive procedures.

Potential Commercial Applications and Market

The adaptive intervertebral cage apparatus and system have significant commercial potential in the spinal implant market, which is projected to grow significantly in the coming years. The system's ability to provide optimal fit, stability, and fusion can reduce revision rates, improve patient outcomes, and increase market share for companies that adopt this technology.
