Thermally Assisted PEMF for Kidney Inflammation
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Current treatments for chronic kidney disease, particularly diabetic nephropathy, are inadequate in reducing inflammation and preventing renal damage, as they fail to effectively target macrophage recruitment and activation, leading to progressive renal fibrosis and end-stage renal disease.
Innovation Solution
A Thermally Assisted Pulse Electromagnetic Field (TA-PEMF) stimulation system that combines thermal and electric stimulation to activate adenosine A2a receptors on kidney cells and immune cells, inhibiting inflammatory responses and promoting tissue repair, while also inducing Heat Shock Proteins to protect kidney cells from apoptosis and necrosis.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If conventional medical treatments are used for chronic kidney disease, then treatment is available for some types of GN, but the treatments are toxic, non-specific and have the potential for major side effects
Solution Approach 1:
The patent replaces conventional pharmacological treatments with a physical field-based approach using pulsed electromagnetic fields (PEMF). This substitution eliminates the need for toxic drugs while maintaining treatment effectiveness through non-invasive electromagnetic stimulation that modulates immune cell function and reduces inflammation in the kidneys
Solution Approach 2:
The patent introduces pulsed electromagnetic fields as an intermediary mechanism to treat chronic kidney disease. The PEMF acts as a mediator that influences immune cell behavior, macrophage recruitment, and inflammatory pathways without direct chemical interaction, thereby avoiding the toxic side effects associated with conventional medications
2Ease of operation
If current treatments fail to effectively target macrophage recruitment and activation, then treatment is provided, but progressive renal fibrosis and end-stage renal disease occur
Solution Approach 1:
The patent employs dynamic pulsed electromagnetic field delivery with varying parameters (frequency, amplitude, pulse duration) to effectively target macrophage recruitment and activation at different stages of disease progression. This dynamic approach allows the treatment to adapt to changing pathological conditions, preventing renal fibrosis while maintaining operational simplicity through automated delivery systems
Solution Approach 2:
The patent utilizes specific parameter ranges of pulsed electromagnetic fields (frequency: 1-100 Hz, amplitude: 0.1-10 V/cm) to selectively modulate macrophage function and inflammatory responses. By optimizing these parameters, the treatment effectively controls disease progression and prevents end-stage renal disease while maintaining a simple treatment protocol

Function Achieved in This Case
The TA-PEMF system effectively reduces kidney inflammation, suppresses excessive immune responses, decelerates the progression of chronic kidney disease, and preserves kidney function by enhancing adenosine A2a signaling and Heat Shock Protein expression, offering a non-invasive, side-effect-free treatment for chronic kidney disease.
Implementation Method 1
delivering a pulsed electromagnetic field (PEMF) to a kidney of the patient... the PEMF inducing an electric field in the kidney cell
Implementation Method 2
Assistant thermal stimulation may be applied to increase expression of heat shock proteins (HSPs) in parenchymal cells

AI summary
A method and apparatus for treatment of chronic kidney disease (CKD), particular diabetic nephropathy, are disclosed. The method comprises activation of adenosine A2a receptors in parenchymal and immune cells infiltrated into kidneys. The activation is performed by PEMF (pulsed electromagnetic field) stimulation applied locally to kidneys. Adenosine A2a signaling pathway is a potent anti-inflammatory and immuno-suppressive regulator that has been proven to attenuate inflammation and injury in diabetic nephropathy. Efficient activation of A2a receptors is achieved by applying electromagnetic field stimulation consecutively in 3 spatial dimensions. This allows attaining a significant increase in activation of A2a receptors in comparison with one-dimensional stimulation. Assistant thermal stimulation may be applied to increase expression of heat shock proteins (HSPs) in parenchymal cells. HSPs improve protein functions, protect cells from apoptosis and necrosis, increase metabolism, and symbiotically enhance effects of electric stimulation on CKD.
