Endoscopic Sleeve Delivery System for Minimally Invasive Obesity Treatment
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Current surgical procedures for obesity treatment are invasive and associated with severe complications, such as organ failure and dumping syndrome, and lack a minimally invasive solution for effectively addressing obesity and related health issues like Type II diabetes.
Innovation Solution
A medical apparatus comprising a delivery tube with a sleeve and anchoring component, designed for minimally invasive implantation via an endoscope, allowing full deployment across tortuous anatomy without extending beyond the anchor placement, utilizing fluoropolymer materials and a sheath for reduced complications and improved efficacy.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If traditional surgical procedures are used to treat obesity, then weight loss can be achieved, but severe complications such as organ failure and dumping syndrome occur
Solution Approach 1:
The patent replaces traditional open surgical mechanical procedures with a minimally invasive endoscopic delivery system. The sleeve device is delivered through the gastrointestinal tract using an endoscope, avoiding external incisions and direct surgical manipulation of organs, thereby eliminating severe surgical complications while achieving the desired weight loss effect
Solution Approach 2:
The patent employs a flexible sleeve made of biocompatible materials that can be delivered in a compressed state and then expanded within the gastrointestinal tract. This flexible structure allows minimally invasive deployment through the endoscope while providing the necessary mechanical function for weight loss treatment without causing organ damage
2Reliability
If invasive surgical procedures are performed, then obesity treatment is effective, but the procedures become complicated and time-consuming
Solution Approach 1:
The patent substitutes complex multi-step surgical procedures with a single minimally invasive endoscopic delivery. The entire treatment device is delivered through the endoscope's working channel in one procedure, dramatically simplifying the treatment process while maintaining effectiveness
Solution Approach 2:
The patent employs a nested delivery mechanism where the sleeve is contained within the delivery tube, which in turn is inserted through the endoscope's working channel. This nested configuration allows the complex device to be delivered through a relatively simple access route, reducing procedural complexity
3Ease of operation
If a delivery tube is designed to accommodate a sleeve, then minimally invasive delivery is enabled, but the delivery tube must fit within the endoscope working channel
Solution Approach 1:
The patent implements a nested configuration where the delivery tube is sized to fit within the endoscope working channel, and the compressed sleeve fits within the delivery tube. This nested arrangement enables minimally invasive delivery through the constrained endoscope access while accommodating all necessary device components
Solution Approach 2:
The patent employs a dynamic delivery system where the sleeve transitions from a compressed state during delivery to an expanded state after deployment. This dynamic transformation allows the device to pass through the narrow endoscope channel in a compressed configuration and then expand to its functional size at the treatment site

AI summary
The invention relates to a medical apparatus including a device used in the treatment of weight loss, obesity and potentially other associated health problems, e.g., type II diabetes. The device is used to impede absorption of nutrients within the gastrointestinal tract, i.e., bypassing a portion of the gastrointestinal tract. The medical apparatus enables implantation of the device using minimally invasive techniques, such a transesophageal approach under visualization. The device may be implanted via a working channel of a medical scope, e.g., an endoscope or in combination with a medical scope.
