Endoscopic Suturing Device for Gastric Constriction
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Current surgical methods for obesity treatment, such as gastric bypass and stapling, are unreliable, cause tissue perforations, and have limited durability due to the use of staples and require invasive procedures, which are technically challenging and lead to complications.
Innovation Solution
A system and method for endoscopic circumferential suturing using an expandable enclosure and suture delivery apparatus within a hollow organ, allowing for the deployment of sutures and grafts to create a gastric constriction by drawing tissue into a circumferential gap and securing it with sutures and rings, reducing the need for invasive procedures.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If traditional surgical methods (gastric bypass and stapling) are used, then obesity treatment can be achieved, but the procedures are invasive and cause tissue perforations
Solution Approach 1:
The patent introduces an intermediary device system that includes a delivery apparatus and receiving apparatus with coordinated tube structures. This intermediary system enables minimally invasive suture deployment through the gastrointestinal tract without requiring open surgical access, thereby eliminating tissue perforation while maintaining treatment reliability
Solution Approach 2:
The patent replaces traditional mechanical stapling systems with a suturing system that uses flexible needles and sutures delivered through coordinated tube apparatus. This substitution eliminates the need for rigid staples that cause perforations, achieving the same constriction effect through a gentler, more reliable mechanical process
2Productivity
If staples are used for gastric constriction, then the procedure can be completed, but durability is limited
Solution Approach 1:
The patent changes the fundamental parameters of the fastening mechanism by replacing staples with sutures that can be tied in a controlled manner. The suture delivery system allows for adjustable tension and secure knotting, creating a more durable constriction that maintains its effect over time while still allowing procedure completion through minimally invasive delivery
3Reliability
If traditional invasive procedures are used, then gastric constriction can be achieved, but surgical complications increase
Solution Approach 1:
The coordinated delivery apparatus and receiving apparatus act as intermediaries that enable the entire suturing process to occur through the gastrointestinal tract lumen. This eliminates the need for external surgical incisions and access, thereby preventing surgical complications while maintaining the efficacy of gastric constriction through the sutured tissue
Solution Approach 2:
The system enables self-service delivery where the sutures are deployed through the gastrointestinal tract using the coordinated action of the delivery and receiving apparatus without requiring external surgical intervention. The system serves itself by utilizing the natural lumen space, thereby eliminating surgical complications while achieving the desired constriction effect
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 approach provides a reliable, durable, and minimally invasive method for obesity treatment by creating a gastric constriction that impedes food intake, offering long-term efficacy and reducing surgical complications.
Implementation Method 1
The central tube optionally comprises a suction port in communication with the lumen of the central tube. The suction port is adapted to be placed in communication with a suction source to evacuate air from the central tube lumen. The evacuation of air from the central tube lumen by the suction source causes organ tissue to enter the circumferential gap.
