Gastrointestinal Constriction via Spreading Blocks
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Current methods for treating gastroesophageal reflux disease, such as PTL 1 and PTL 2, involve invasive procedures like tissue removal or scarring, which are not always effective in preventing excessive constriction and have limitations in controlling the spread of substances like ethanol within the gastrointestinal tract.
Innovation Solution
A gastrointestinal tract constricting method that forms spreading blocks between the mucosa and muscle layers using a sodium hyaluronate solution or cauterization, preventing the spread of substances like ethanol in a circumferential direction, thereby controlling tissue damage and constriction.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If tissue removal or scarring methods are used to constrict the gastrointestinal tract, then constriction effect is achieved, but excessive constriction and uncontrolled substance spread occur
Solution Approach 1:
The spreading blocks are formed in advance before supplying the substance (ethanol) to the target region. This preliminary action creates barriers that pre-control the spread path of the substance, preventing excessive constriction while ensuring reliable constriction effect in the desired area.
Solution Approach 2:
The gastrointestinal tract treatment area is segmented into a target region (where constriction is desired) and adjacent regions (protected by spreading blocks). The spreading blocks physically divide the space, allowing controlled substance delivery to the target region while protecting adjacent areas from excessive substance spread.
2Reliability
If invasive procedures like tissue removal are performed, then constriction is achieved, but the procedure becomes complex and highly invasive
Solution Approach 1:
Spreading blocks act as intermediary elements between the substance delivery system and the gastrointestinal tract tissue. Instead of directly removing or scarring tissue, the spreading blocks mediate the constriction process by controlling substance distribution, reducing procedure invasiveness while maintaining constriction reliability.
Solution Approach 2:
The invention changes the approach from direct tissue manipulation (removal/scarring) to controlled chemical treatment via substance delivery. By altering the constriction mechanism from mechanical to chemical-biological, the procedure becomes less invasive while achieving similar constriction effects.
3Reliability
If substance is supplied to constrict the gastrointestinal tract, then constriction effect is achieved, but substance spreads to outer regions causing excessive damage
Solution Approach 1:
Spreading blocks are formed in advance before substance supply to create protective barriers. This preliminary positioning prevents substance from reaching outer regions, eliminating excessive damage while preserving the constriction effect in the target area.
Solution Approach 2:
The harmful spread of substance to outer regions is extracted or removed from the system by introducing spreading blocks that act as barriers. The substance is effectively contained within the target region, preventing harmful effects in adjacent areas.

AI summary
A gastrointestinal tract constricting method according to the present invention aims to constrict the gastrointestinal tract by contracting a desired region of the gastrointestinal tract by a simple and low-invasive procedure. The method includes forming spreading blocks while observing the gastrointestinal tract with an endoscope inserted into the gastrointestinal tract, the spreading blocks being formed at a position between a mucosa layer and a muscle layer and on both sides of a target region, which is to be damaged by a substance, in a circumferential direction of the gastrointestinal tract so that the spreading blocks block spreading of the substance in the circumferential direction of the gastrointestinal tract to prevent spreading of the substance to an outer side of the target region, and supplying the substance to a mucosal surface of the target region or to the position between the mucosa layer and the muscle layer after formation of the spreading blocks.
