Endoscopic Balloon Segmentation for Diverticular Hemostasis
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Bleeding from colonic diverticula is challenging to stop due to difficulty in identifying and reaching the bleeding point within the tubular organ, especially when multiple diverticula are involved, as existing endoscopic hemostatic treatments are complicated and require precise drug administration.
Innovation Solution
A treatment method and system using a first and second closing member, such as balloons, to isolate the diverticulum within a tubular organ, followed by suctioning gas to create negative pressure and contacting a holding member with the diverticulum to bring mucous membranes into close contact, effectively stopping bleeding without the need for large drug administration.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If endoscopic hemostatic treatment is used to stop bleeding from multiple colonic diverticula, then bleeding can be stopped, but it is difficult to identify the bleeding point and the treatment becomes complicated
Solution Approach 1:
The treatment device segments the tubular organ into isolated sections using first and second closing members (balloons) to create a closed space around the affected diverticulum. This segmentation allows focused treatment of the bleeding area without needing to identify or treat multiple diverticula simultaneously, simplifying the overall treatment process while maintaining effectiveness.
Solution Approach 2:
The patent introduces a holding member as an intermediary element between the closing members that directly contacts the diverticulum to apply hemostatic action. This intermediary structure enables effective treatment by mechanically holding and compressing the bleeding diverticulum within the closed space, reducing treatment complexity compared to direct endoscopic intervention on multiple bleeding points.
2Reliability
If a large amount of drug is administered to stop bleeding in a colonic diverticulum, then bleeding can be stopped, but the drug must reach inside the diverticulum which is difficult to achieve
Solution Approach 1:
The device creates a localized treatment environment by closing off a specific section of the tubular organ containing the bleeding diverticulum. This local quality approach concentrates the therapeutic effect within the closed space, allowing drugs or other hemostatic agents to act locally on the bleeding site without requiring large quantities to be distributed throughout the entire organ.
Solution Approach 2:
The patent uses pneumatic pressure by inflating closing members (balloons) to create a closed space, and potentially uses pressure differentials to deliver drugs or fluids directly to the bleeding diverticulum. This pneumatic mechanism enables precise drug delivery to the target area without requiring large drug quantities, as the closed space prevents drug dispersion.
3Ease of operation
If conservative treatments such as fasting and resting the intestines are used, then treatment is simple, but bleeding cannot be stopped when it occurs in multiple colonic diverticula
Solution Approach 1:
The device segments the affected area by closing off individual diverticula or sections containing multiple diverticula between closing members. This segmentation transforms a complex multi-point bleeding problem into isolated, manageable sections that can be treated effectively, maintaining treatment simplicity while improving reliability compared to conservative methods alone.
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 method and system enable efficient and effective cessation of bleeding from colonic diverticula, even when multiple diverticula are bleeding, by creating a closed space and applying suction to bring the mucous membranes into contact, preventing further bleeding without requiring extensive drug delivery.
Implementation Method 1
suctioning gas within the part of the tubular organ between the first closing member and the second closing member

AI summary
A treatment method according to one aspect of the present disclosure may include inserting a first closing member and a second closing member into a tubular organ having at least one concaved area, and closing a part of the tubular organ with the first closing member and the second closing member in a state where the at least one concaved area is located between the first closing member and the second closing member. The method may further include disposing a holding member between the first closing member and the second closing member, and suctioning gas within the part of the tubular organ between the first closing member and the second closing member and contacting the holding member with a portion of the at least one concaved area.
