Disc Height Restoration via Stem Cell Regeneration
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Current treatments for disc degeneration, which involves the loss of water-holding capacity and mechanical stability of intervertebral discs, do not effectively slow down, impede, or stop the degeneration process, leading to back pain and reduced mobility due to nerve compression and disc height reduction.
Innovation Solution
A method involving the use of a vertebral disc annular fibrosis tensioning and lengthening device to restore disc height, followed by injection of stem cells that differentiate into chondrocytes and notochordal cells to facilitate disc regeneration, thereby addressing the degenerative issues.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If surgical fusion or disc replacement is performed, then disc stability is improved, but loss of spinal mobility and natural disc function occurs
Solution Approach 1:
The patent utilizes the body's own stem cells to regenerate disc tissue, allowing the disc to repair itself rather than requiring external mechanical replacement. The stem cells are harvested from the patient's own body, differentiated into notochordal-like cells, and injected back into the disc to restore its natural structure and function, maintaining both stability and mobility.
Solution Approach 2:
The patent replaces mechanical surgical interventions (fusion hardware, artificial discs) with a biological regeneration system. Instead of using metal implants or synthetic materials to provide stability, the invention uses biologically active stem cells that naturally regenerate the disc matrix, providing stability through restored tissue integrity rather than mechanical constraint.
2Reliability
If stem cells are injected into the disc, then disc regeneration is promoted, but the complexity of the treatment procedure increases
Solution Approach 1:
The treatment is divided into distinct sequential steps: (1) harvesting stem cells from the patient's body, (2) differentiating them into notochordal-like cells in a laboratory setting, (3) injecting the differentiated cells into the disc, and (4) providing post-treatment care. This segmentation allows each step to be optimized independently and makes the complex process more manageable and controllable.
Solution Approach 2:
Stem cells are harvested and differentiated into notochordal-like cells before being injected into the disc. This preliminary preparation ensures that the cells are in the optimal state for regeneration when introduced to the disc, improving treatment efficacy while allowing the actual injection procedure to be relatively simple.
3Strength
If disc height is restored using tensioning device, then mechanical stability is improved, but the underlying cellular degeneration remains untreated
Solution Approach 1:
The patent combines two treatments into a comprehensive approach: mechanical restoration using a tensioning device to restore disc height and provide immediate stability, combined with biological regeneration using stem cells to address the underlying cellular degeneration. This merging ensures both immediate mechanical support and long-term cellular health.
Solution Approach 2:
The tensioning device is used first to restore disc height and create space, which then facilitates the subsequent injection and effectiveness of stem cells. The mechanical restoration prepares the disc structure to better receive and utilize the regenerative cells, optimizing the overall treatment outcome.
Applied Scientific Principles
This section explains which scientific principles are used to turn an abstract innovation direction into a practical engineering solution.
Function Achieved in This Case
The method effectively regenerates the disc by restoring its height and water-holding capacity, reducing back pain and improving mobility by promoting the growth of healthy disc tissue, potentially replacing the need for surgical interventions like fusion and disc replacement.
Implementation Method 1
injecting stem cells into the disc that differentiate into chondrocytes and/or notochordal cells that facilitate disc regeneration

AI summary
A method for providing disc regeneration that includes at least partially restoring disc height using a vertebral disc annular fibrosis tensioning and lengthening device, and then injecting a biologic substance, such as stem cells, into the disc that differentiate into chondrocytes and/or notochordal cells that facilitate disc regeneration. Once the biologic substance has regenerated the disc, it may be possible to remove the vertebral disc annular fibrosis tensioning and lengthening device.
