Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Current diabetes treatment methods, such as gastric bypass surgery and intestinal bypass liners, are invasive, costly, and pose risks, while existing devices for intestinal barrier sleeve release systems are complex and difficult to operate, limiting their widespread application and accessibility.
Innovation Solution
An intestinal barrier sleeve release system guided by a gastroscope, featuring a tubular housing with a dissolvable release body and a push assembly, which separates intestinal tissues from food, improving insulin secretion and diabetes treatment with a simple structure, low manufacturing cost, and reduced risk of complications.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If gastric bypass surgery is performed to treat diabetes, then the treatment effectiveness is improved, but surgical risks and complications increase
Solution Approach 1:
The patent replaces traditional surgical mechanical intervention (gastric bypass surgery) with a minimally invasive endoscopic delivery system. The intestinal barrier sleeve is delivered through the gastrointestinal tract using an endoscope and guidewire, avoiding external surgical incisions and reducing surgical risks while maintaining treatment effectiveness for diabetes and obesity.
Solution Approach 2:
The patent introduces an intestinal barrier sleeve as an intermediary device that creates a physical barrier in the duodenum. This sleeve acts as a mediator between food intake and nutrient absorption, allowing controlled passage of nutrients while preventing excessive calorie absorption, thereby treating obesity and diabetes without direct surgical modification of organs.
2Reliability
If intestinal bypass liner is used to treat diabetes, then treatment effectiveness is improved, but device complexity and operational difficulty increase
Solution Approach 1:
The delivery system is segmented into distinct functional modules: an outer sheath for protection, an inner sheath for deployment, a push rod for advancement, and the intestinal barrier sleeve itself. This segmentation allows each component to perform its specific function independently, simplifying the overall operation and reducing the complexity of managing multiple simultaneous actions required by previous single-piece designs.
Solution Approach 2:
The intestinal barrier sleeve is pre-formed and sterilized before use, and the delivery system is pre-assembled with all components in place. The endoscopist simply needs to advance the system through the GI tract and deploy the sleeve, eliminating the need for complex intra-procedural assembly or multiple separate操作步骤, thereby reducing operational difficulty.
3Reliability
If intestinal bypass liner is used to treat diabetes, then treatment effectiveness is improved, but manufacturing cost increases
Solution Approach 1:
The intestinal barrier sleeve is constructed from thin, flexible biocompatible materials that can be manufactured using standard medical device fabrication techniques. The sleeve utilizes a simple tubular structure with radial expandability, avoiding complex multi-layer constructions or specialized materials, thereby reducing manufacturing costs while maintaining effectiveness for creating the intestinal barrier.
4Object-affected harmful factors
If dissolvable release body is used in intestinal barrier sleeve release system, then surgical risks are reduced, but device complexity increases
Solution Approach 1:
The release body is designed to change its physical state from solid to dissolved form through a parameter change (exposure to gastrointestinal fluids). This chemical/physical transformation automatically triggers the release mechanism, eliminating the need for complex mechanical actuators or controlled deployment systems. The dissolving property of the release body itself becomes the driving force for sleeve deployment, simplifying the overall mechanism.
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 system effectively treats type 2 diabetes and obesity with minimal pain and quick recovery, as the dissolvable release body is absorbed by the body, reducing surgical risks and promoting better quality of life without the need for dietary restrictions.
Implementation Method 1
The release body is disposed at the first opening, connected to one end of the tubular sleeve, and made of a material that is able to be dissolved and absorbed in human intestines
