Magnetic Occlusion Caloric Bypass Device
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Current methods for treating obesity, such as surgical procedures and medical devices, often involve invasive techniques that are not reversible and can lead to malnutrition or require patient input, failing to effectively differentiate between healthy and unhealthy food components for caloric absorption.
Innovation Solution
A passive caloric bypass device with an inflatable separative collection element and distal transport member is deployed in the gastrointestinal tract, redirecting unhealthy food components while allowing healthy nutrients to be absorbed, providing a reversible and non-invasive solution that mimics the duodenal switch mechanism without patient input.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Loss of energy
If surgical procedures like gastric bypass or biliopancreatic diversion are performed to reduce caloric absorption, then weight loss is achieved, but the procedures are invasive, irreversible, and can lead to malnutrition
Solution Approach 1:
The patent introduces an intermediary device - a magnetic occlusion system with a magnetically actuable occlusion element that can be remotely controlled to block or allow passage of food particles. This intermediary mechanism enables temporary, reversible control of caloric absorption without permanent surgical alteration, resolving the contradiction between effective caloric restriction and avoidance of invasive permanent damage
Solution Approach 2:
The occlusion element transitions from a static surgical modification to a dynamic, remotely controllable system. The magnetically actuable occlusion element can be moved between different positions (occluding vs. non-occluding) based on dietary needs, allowing adaptive control of caloric absorption while maintaining the ability to restore normal function when needed
2Productivity
If the stomach size is reduced through stapling or gastroplasty to achieve faster satiety, then early weight loss is obtained, but the stomach stretches over time and patients find ways to eat around the smaller pouch
Solution Approach 1:
The system provides feedback through remote magnetic control, allowing the occlusion state to be adjusted based on patient compliance and dietary requirements. This feedback mechanism ensures the stomach volume reduction effect is maintained over time without stretching, as the occlusion can be reactivated if compliance lapses, unlike static surgical modifications
3Loss of energy
If large lengths of jejunum are bypassed in BPD procedure to reduce caloric uptake, then malabsorption and reduced caloric uptake are achieved, but serious side effects of prolonged malabsorption occur
Solution Approach 1:
The magnetic occlusion system applies partial action by selectively blocking only undigested food particles while allowing digestive enzymes and nutrients to pass. This partial occlusion achieves caloric reduction without the excessive malabsorption side effects of BPD, maintaining nutritional balance while still reducing caloric uptake effectively
4Duration of action of moving object
If invasive surgical procedures are performed to alter digestive tract anatomy, then long-term weight loss is achieved, but the procedures require high operative skill and expose patients to high operative risk
Solution Approach 1:
The patent replaces complex mechanical surgical procedures with a simpler magnetic field-based system. Instead of performing complex anastomoses and anatomical alterations requiring high operative skill, a magnetic field is used to actuate the occlusion element remotely, significantly reducing procedure complexity while maintaining sustained weight loss effectiveness
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 reduces the absorption of unhealthy food components, providing negative biological feedback to inhibit the ingestion of simple sugars and carbohydrates, promoting weight loss while maintaining essential nutrient absorption, and is designed for temporary use with potential for retrieval.

AI summary
A novel medical device for treating obesity is disclosed. The device is inserted through the oral cavity and into the digestive tract of a human. The device is a passive catheter-style structure that preferentially directs a significant volume of the high calorie fluidic components of the chyme through the digestive tract, preventing exposure to the absorptive tissues of the digestive tract and, in some forms, stimulates negative feedback to the patient when simple sugars and carbohydrates are consumed. The device may be installed or removed though the use of standard endoscopy, or may be offered in the form of an ingestible device. The device may be inflatable or preformed for use within the digestive tract. Also disclosed is a novel method of using the medical device to control obesity.
