High Frequency Electric Field for Chronic Wound Healing
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Current treatments for diabetic ulcers and chronic wounds, which result from hypoxia and compromised wound healing processes, are limited in effectiveness, and there is a lack of FDA-approved devices for wound healing using electric fields.
Innovation Solution
Exposure of tissues to high frequency electric fields, specifically in the range of 1 GHz to 10 GHz, to induce wound healing, activate the MAPK/ERK pathways, and stimulate the expression of angiogenic factors such as NO and VEGF, promoting angiogenesis and improving wound healing.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If conventional wound therapy techniques are used, then wound healing is supported, but treatment effectiveness is limited for chronic wounds and diabetic ulcers
Solution Approach 1:
The patent applies high frequency electromagnetic fields (1-10 GHz) with specific field strengths (1-100 V/m) to tissue, changing the physical parameters of the treatment from conventional mechanical/chemical therapies to electromagnetic stimulation. This parameter change activates cellular pathways including MAPK/ERK signaling and increases expression of angiogenic factors, thereby improving wound healing effectiveness and accelerating healing rates in chronic wounds and diabetic ulcers
2Reliability
If low frequency electromagnetic fields are used for wound healing, then some therapeutic effect is achieved, but widespread acceptance and FDA approval have not been obtained
Solution Approach 1:
The patent shifts from low frequency to high frequency (1-10 GHz) electromagnetic fields, changing the frequency parameter to a range previously not explored for wound healing. This high frequency range produces distinct biological effects including enhanced angiogenesis and vascular endothelial growth factor expression, providing a novel therapeutic approach that addresses both efficacy and regulatory acceptance needs
3Reliability
If high frequency electromagnetic fields are applied, then angiogenesis and wound healing are enhanced, but the mechanism differs from conventional low frequency approaches
Solution Approach 1:
The patent utilizes high frequency electromagnetic fields to directly stimulate cellular pathways including MAPK/ERK signaling and increase expression of angiogenic factors such as VEGF, NO, and FGF. This mechanism differs from low frequency approaches by activating intracellular signaling cascades through electromagnetic field-induced cellular responses, providing a more direct and potent angiogenic stimulus
