Solution Overview

Problem

Current endoscopic treatments for gastroesophageal reflux disease (GERD), obesity, Type 2 Diabetes Mellitus, and iatrogenic perforations face challenges such as high cost, extensive training requirements, lack of long-term efficacy, and inadequate tissue capture, leading to complications like bleeding, perforation, and limited therapeutic outcomes.

Innovation Solution

The use of endoscopic barrels and retention bands for band-assisted pressure necrosis, which capture and retain mucosal, submucosal, and muscle layers to induce controlled ischemia and subsequent fibrosis, reshaping gastrointestinal organs without resection or invasive procedures.

Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Reliability

If endoscopic barrels and retention bands are used for band-assisted pressure necrosis, then tissue retention and procedural safety are improved, but device complexity increases

Engineering Contradiction:

Improveprocedural safetyVSAvoiddevice complexity

Core Design Contradiction:

ReliabilityVSDevice complexity

Solution Approach 1:

The retention band is nested within the endoscopic barrel, with the band positioned inside the barrel's lumen. The barrel serves as a delivery mechanism that contains and deploys the band to the target tissue site, creating a nested configuration that integrates multiple functions into a unified device structure.

Inventive Principle:

Principle #7Nested doll (Nesting)

Solution Approach 2:

The device is segmented into distinct functional components: the endoscopic barrel for delivery and positioning, the retention band for tissue capture and constriction, and the deployment mechanism. This segmentation allows each component to be optimized for its specific function while maintaining overall system integration.

Inventive Principle:

Principle #1Segmentation

2Manufacturing precision

If extensive training requirements are imposed on endoscopic procedures, then treatment precision is improved, but ease of operation deteriorates

Engineering Contradiction:

Improvetreatment precisionVSAvoidease of operation

Core Design Contradiction:

Manufacturing precisionVSEase of operation

Solution Approach 1:

The retention band is designed to self-constrict around the captured tissue through its elastic properties, eliminating the need for complex external tightening mechanisms. The band automatically adjusts to the tissue geometry and maintains consistent pressure through its material properties, reducing the skill level required for precise application.

Inventive Principle:

Principle #25Self-service

Solution Approach 2:

The retention band's elastic modulus and dimensional parameters are specifically engineered to provide optimal constriction force and tissue retention. By pre-configuring these physical parameters, the device achieves consistent treatment outcomes without requiring extensive operator skill to adjust forces or positioning during the procedure.

Inventive Principle:

Principle #35Parameter changes

3Reliability

If costly proprietary capital equipment is required for endoscopic treatments, then treatment efficacy is improved, but accessibility deteriorates

Engineering Contradiction:

Improvetreatment efficacyVSAvoidaccessibility

Core Design Contradiction:

ReliabilityVSAdaptability or versatility

Solution Approach 1:

The endoscopic barrel and retention band system is designed to be compatible with standard endoscopic platforms and can be used for multiple gastrointestinal procedures beyond GERD treatment, including obesity management and other mucosal pathologies. This multi-functionality allows existing endoscopic infrastructure to be utilized, reducing the need for proprietary capital equipment.

Inventive Principle:

Principle #6Universality (Multi-functionality)

Solution Approach 2:

The retention band is designed as a disposable component that can be sterilized and reused a limited number of times, or replaced if contaminated. This approach eliminates the need for expensive, complex reusable instruments while maintaining sterility and treatment efficacy, making the procedure more accessible to a broader range of healthcare facilities.

Inventive Principle:

Principle #27Cheap short-living objects (Disposable)
