Abdominal Electrical Stimulation for Non-Invasive GERD Relief
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing treatments for gastroesophageal reflux disease (GERD) are invasive, have adverse effects, and limited efficacy, while non-invasive alternatives lack effectiveness and are not well-suited for long-term use.
Innovation Solution
A non-invasive device that stimulates the abdomen muscles with controlled electrical bursts to affect esophageal motility, strengthen the esophageal sphincter, and synchronize stimulation with patient signals to optimize treatment efficacy.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If medication therapy (PPI, H2 receptor blockers, antacids) is used to treat GERD, then symptom relief is achieved in up to 60% of patients, but long-term use is associated with various adverse effects and safety concerns
Solution Approach 1:
The patent replaces chemical medication therapy with a physical/electrical stimulation system. The device uses electrical bursts delivered through electrodes to stimulate abdominal muscles and digestive system movements, substituting the chemical mechanism of PPIs and H2 blockers with an electrical/mechanical stimulation approach that avoids pharmacological adverse effects while maintaining GERD treatment efficacy
Solution Approach 2:
The device enables patients to self-administer treatment at home without requiring ongoing medical supervision or prescription refills. The portable design with integrated power supply allows patients to independently apply electrical stimulation therapy, reducing long-term dependency on medical systems and eliminating the need for continuous medication management
2Object-affected harmful factors
If surgical therapy (fundoplication) or endoscopic interventions are used to treat GERD, then an alternative to long-term medication is provided, but these procedures are associated with adverse effects, poor efficacy, and complications that limit their use
Solution Approach 1:
The patent replaces invasive surgical and endoscopic mechanical interventions with non-invasive electrical stimulation. Instead of physically altering anatomy through fundoplication or endoscopic devices, the system uses electrical bursts to stimulate natural digestive movements and sphincter function, achieving GERD control without surgical risks, complications, or anatomical modifications
Solution Approach 2:
The device introduces electrical stimulation as an intermediary mechanism between the patient's nervous system and digestive muscle function. Rather than directly manipulating digestive structures through surgery or endoscopy, the electrical bursts act as a mediator to modulate muscle contractions, sphincter tone, and gastrointestinal motility, providing a safer intermediate approach that avoids direct tissue intervention
3Ease of operation
If existing non-invasive devices are used for GERD treatment, then patient comfort is improved, but effectiveness and suitability for long-term use are insufficient
Solution Approach 1:
The device employs dynamic electrical stimulation parameters including variable burst frequencies (0.5-10 Hz), adjustable pulse durations (10-500 ms), and programmable treatment protocols that adapt to different digestive states. This dynamic capability allows the same non-invasive device to effectively treat multiple conditions (GERD, gastroparesis, constipation, obesity) by adjusting stimulation patterns, providing both comfort and versatility for long-term use
Solution Approach 2:
The patent designs a universal non-invasive device that can treat multiple gastrointestinal conditions through a single system. By programming different electrical stimulation protocols, the device addresses GERD, gastroparesis, constipation, and obesity, eliminating the need for multiple specialized devices while maintaining non-invasive comfort and achieving effective treatment across diverse gastrointestinal disorders
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 device effectively manages GERD symptoms by enhancing esophageal motility, preventing reflux, and providing satiation for obesity treatment, while being safe for daily use.

AI summary
A non-invasive device for facilitating therapy of patient suffering from the gastrointestinal system diseases or symptoms, and in particular suffering Gastroesophageal reflux disease (GERD). The device is positioned by the patient on the skin of the patient abdomen and electrically stimulates the abdomen muscles. This treating results in dynamic motions of the digestive system, which causes the treatment of various digestive symptoms or diseases.
