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 solutions for gastric volume reduction.
Innovation Solution
A transoral endoscopic device for plicating and fastening gastric tissue, using an elongated member with a rotatable end effector and vacuum system to create tissue folds, which can be secured with staples or clips, allowing for adjustable gastric volume reduction without open surgery.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If gastric bypass or adjustable gastric band is used for gastric volume reduction, then obesity treatment effectiveness is improved, but invasiveness increases and risks of complications (malnutrition, dumping syndrome) worsen
Solution Approach 1:
The patent replaces traditional mechanical surgical interventions (gastric bypass, adjustable gastric bands) with an endoscopic device that uses vacuum suction and mechanical plication through a natural body orifice. This substitution eliminates the need for external implants and complex surgical anastomoses, thereby reducing complications like malnutrition and dumping syndrome while maintaining obesity treatment effectiveness through gastric volume reduction
Solution Approach 2:
The patent introduces an endoscopic device as an intermediary tool that performs gastric plication without requiring open surgery or permanent implants. The device uses vacuum suction to gather gastric tissue and creates plications through a controlled mechanical process, serving as a temporary mediator that achieves gastric restriction without the long-term harmful effects of traditional surgical methods
2Volume of stationary object
If traditional surgical methods are used for gastric plication, then gastric volume reduction is achieved, but patient discomfort and reversibility issues worsen
Solution Approach 1:
The patent replaces traditional surgical plication methods with an endoscopic approach that uses vacuum suction and a specialized end effector to create tissue folds. This mechanical substitution allows the procedure to be performed through a natural body orifice, significantly reducing patient discomfort and making the procedure more reversible compared to traditional open surgery
Solution Approach 2:
The patent extracts the plication function from traditional surgical procedures and implements it through a removable endoscopic device. The device can be inserted, perform the plication, and then removed, leaving no permanent foreign bodies. This extraction approach enhances patient comfort and facilitates potential reversibility if needed
3Object-affected harmful factors
If minimally invasive techniques are used, then patient trauma is reduced, but surgical difficulty and mastery complexity increase
Solution Approach 1:
The patent designs an endoscopic device with multiple functions integrated into a single system: vacuum suction for tissue gathering, mechanical plication through rotatable cylinders, and fastening capabilities. This multi-functionality reduces the need for multiple separate instruments, simplifying the surgical procedure while maintaining minimal invasiveness and reducing patient trauma
4Volume of stationary object
If gastric band is implanted to encircle the stomach, then gastric restriction is achieved, but invasiveness and procedural complexity worsen
Solution Approach 1:
The patent extracts the gastric restriction function from permanent implanted bands and achieves it through temporary endoscopic plications. The procedure creates tissue folds that restrict gastric volume without requiring implantation of foreign bodies, thereby simplifying the procedure and eliminating the complexity associated with band implantation, adjustment, and removal
Solution Approach 2:
The patent employs a disposable or removable endoscopic device that performs the gastric plication and is then withdrawn. This approach replaces permanent implants with a temporary intervention, reducing procedural complexity and eliminating the long-term management issues associated with implanted gastric bands

AI summary
A device for creating a plication within a hollow organ. The device has an elongated member with distal and proximal ends. The distal end is for insertion into a body cavity. The elongated member has an end effector at its distal end. The end effector includes an outer cylinder having at least one opening in its cylindrical wall. The end effector also has an inner cylinder having at least one opening in its cylindrical. The inner cylinder is at least partially disposed within the outer cylinder such that the apertures can at least partially overlap. In addition, the cylinders are rotatable with respect to each other. In addition, the device includes a tubular channel running through the elongated member which is in fluid communication with the end effector. The channel has a vacuum source attached at its proximal end.
