Endoscopic Gastric Tissue Plication via Rotating Cylinders
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Current methods for treating morbid obesity, such as gastric bypass and adjustable gastric bands, are invasive, carry risks, and have drawbacks like malnutrition and dumping syndrome, prompting a need for less invasive and reversible procedures.
Innovation Solution
A transoral method using an endoscopic tissue plicating device with a detachable end effector that creates plications in the gastric tissue by rotating concentric cylinders to reduce stomach volume, secured with staples or clips, allowing for easy reversal.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Volume of moving object
If gastric bypass or adjustable gastric band procedures are performed, then gastric volume reduction is achieved, but patient trauma and surgical invasiveness increase
Solution Approach 1:
The patent replaces traditional mechanical surgical cutting and stapling instruments with an endoscopic system that uses controlled energy delivery (electrosurgery, ultrasonic, or laser energy) to create plications. This substitution allows for less invasive tissue manipulation through natural body orifices rather than external surgical incisions, reducing surgical trauma while achieving gastric volume reduction through tissue folding and securing.
2Volume of moving object
If gastric bypass or gastric band procedures are performed, then gastric volume reduction is achieved, but procedure reversibility decreases
Solution Approach 1:
The patent creates multiple discrete plications at different locations within the stomach rather than a single continuous alteration. Each plication is an independent fold secured by its own fastening element, allowing selective removal or modification of individual plications without affecting the entire gastric structure. This segmented approach enables partial reversibility or adjustment of the procedure's effects.
3Volume of moving object
If gastric bypass or gastric band procedures are performed, then gastric volume reduction is achieved, but malnutrition and dumping syndrome risks increase
Solution Approach 1:
The patent extracts only the volume-restriction function from complex gastric bypass procedures, achieving stomach volume reduction through localized plications without altering the normal anatomical connections between the stomach and intestines. By removing the malabsorption component (bypassing intestinal sections) and retaining only the restriction mechanism (folding stomach tissue), the procedure eliminates risks of malnutrition and dumping syndrome while maintaining normal food processing and absorption pathways.
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
This method effectively reduces gastric volume without the trauma of open surgery, providing a less invasive and reversible bariatric treatment with reduced risks and side effects.
Implementation Method 1
The method also involves the step of applying vacuum through the elongated member so as to dispose tissue within the inner cylinder

AI summary
A method of implanting a device to maintain a plication within a hollow organ. The method uses an elongated member having an end effector at its distal end. The end effector has an outer cylinder having at least one opening, and an inner cylinder having at least one opening. The inner cylinder is at least partially disposed within the outer cylinder and the cylinders are rotatable with respect to each other. The end effector is detachable from the elongated member such that it can remain within the body cavity. The method involves the step of inserting the end effector within the organ of a patient such that it is in contact with tissue. The method also involves the step of applying vacuum through the elongated member so as to dispose tissue within the inner cylinder. The method also involves the step of creating a plication by rotating the cylinders with respect to each other. The method also involves the step of detaching the end effector from the elongated member.
