Endoscopic GI Bypass Anastomosis for Reflux-Resistant Weight Loss
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing surgical and endoscopic procedures for treating obesity and metabolic diseases, such as bariatric surgery, suffer from poor patient acceptance, invasiveness, and complications like bile reflux, despite their effectiveness in weight loss and diabetes resolution.
Innovation Solution
Endoscopic devices and methods are developed to create a single anastomosis in the gastrointestinal tract using a balloon over-tube, illuminated snare, and self-expanding stents to bypass segments of the intestine, anchored with magnetized components, reducing caloric uptake and preventing reflux.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If traditional bariatric surgery is performed, then weight loss and diabetes resolution are achieved, but patient acceptance is poor and invasiveness is high
Solution Approach 1:
The patent replaces traditional surgical mechanical procedures with endoscopic technology. The endoscopic system delivers energy (radiofrequency, microwave, or laser) through the gastrointestinal tract to create gastric pouches and anastomoses without external incisions, thereby maintaining surgical effectiveness while dramatically improving patient acceptance through minimally invasive access
Solution Approach 2:
The patent introduces an endoscope as an intermediary device that mediates between the external environment and the gastrointestinal tract. This intermediary allows energy delivery and tissue manipulation from within the GI tract, eliminating the need for external surgical incisions and improving patient comfort and acceptance
2Reliability
If single anastomosis gastric bypass is performed, then weight loss and diabetes resolution are improved, but bile reflux occurs causing gastritis and esophagitis
Solution Approach 1:
The patent segments the gastrointestinal tract into distinct functional zones using multiple magnetic anchors positioned at different locations. This segmentation creates controlled barriers that maintain the therapeutic bypass effect while preventing bile reflux by isolating the gastric pouch from the biliary system
Solution Approach 2:
The patent applies different local qualities to different regions of the gastrointestinal tract. Magnetic anchors are positioned specifically at the gastroesophageal junction and other critical locations to provide localized anti-reflux protection while maintaining overall bypass functionality. The energy delivery is also localized to create specific tissue modifications without affecting surrounding areas
3Ease of operation
If endoscopic techniques are used, then invasiveness is reduced and patient acceptance improves, but device complexity increases
Solution Approach 1:
The patent merges multiple functions into a single endoscopic device. The endoscope integrates energy delivery capabilities (radiofrequency, microwave, or laser), magnetic anchor deployment mechanisms, and tissue manipulation tools, thereby reducing the need for multiple separate devices and procedures while maintaining minimally invasive access
Solution Approach 2:
The endoscopic system is designed with universal multi-functionality to perform multiple surgical tasks through a single access point. The device can create gastric pouches, form anastomoses, deploy magnetic anchors, and control reflux all through the same endoscopic platform, reducing overall system complexity despite the advanced capabilities
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 endoscopic technique achieves weight loss and improved diabetes control by bypassing longer intestinal segments with minimal invasiveness, addressing bile reflux and enhancing patient acceptance.
Implementation Method 1
The magnetic anchors are configured to anchor the bypass device to a gastrointestinal tract wall
Implementation Method 2
The first stent comprises a first self-expanding framework
