Solution Overview

Problem

Current surgical techniques for procedures like Roux-en-Y gastric bypass (RYGBP) face high complication rates due to anastomotic strictures and leaks, particularly in laparoscopic methods, which require extensive surgical skills and are associated with significant morbidity and mortality.

Innovation Solution

The development of endoscopic devices and systems that enable minimally invasive surgery without sutures or staples, using a tubular member with vacuum channels and suction ports to form reversible seals, allowing for telescopic advancement and deployment of stents to create anastomoses between tissues or organs, thereby bypassing the duodenum endoscopically.

Engineering Contradictions & Design Principles

1Object-affected harmful factors

If laparoscopic surgery is used for RYGBP, then minimally invasive approach is achieved, but anastomotic strictures and leaks occur with high frequency

Engineering Contradiction:

Core Design Contradiction:

Object-affected harmful factorsVSReliability

Solution Approach 1:

The patent replaces mechanical suturing and stapling systems with an endoscopic device that uses vacuum suction to create reversible seals and form anastomoses. The tubular member with vacuum channels draws tissues together to create sealed connections without external incisions or traditional surgical fastening mechanisms, thereby eliminating the mechanical trauma that causes strictures and leaks

Inventive Principle:

Principle #28Mechanics substitution (Replace mechanical system)

Solution Approach 2:

The patent introduces a tubular member as an intermediary device that mediates the connection between gastrointestinal tissues. This device provides a controlled environment for anastomosis formation, using vacuum suction to bring tissues into apposition and maintain sealed connections during healing, reducing the harmful effects of direct tissue approximation

Inventive Principle:

Principle #24Intermediary (Mediator)

Core Design Contradiction:

ReliabilityVSObject-affected harmful factors

Solution Approach 1:

The patent replaces the mechanical trauma of open surgical incisions and suturing with an endoscopic vacuum-based system. The tubular member delivers the anastomosing device through the lumen without external incisions, using vacuum suction to create seals and form connections, thereby maintaining anastomotic integrity while eliminating the morbidity and mortality associated with open surgery

Inventive Principle:

Principle #28Mechanics substitution (Replace mechanical system)

Solution Approach 2:

The patent employs a flexible tubular member that can navigate through the gastrointestinal lumen and adapt to the anatomical structures. This flexible delivery system allows access to the surgical site without rigid incisions, reducing trauma while maintaining the ability to form secure anastomoses

Inventive Principle:

Principle #30Flexible shells and thin films

3Reliability

If endoscopic device with vacuum channels is used, then anastomotic strictures and leaks are reduced, but device complexity increases

Engineering Contradiction:

Core Design Contradiction:

ReliabilityVSDevice complexity

Solution Approach 1:

The tubular member serves multiple functions: it acts as a delivery catheter, provides vacuum suction for tissue approximation, contains the anastomosing device, and facilitates the formation of sealed anastomoses. By combining these functions in a single integrated device, the patent reduces the number of separate components needed, thereby managing device complexity while achieving reliable anastomotic results

Inventive Principle:

Principle #6Universality (Multi-functionality)

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 reduces the risk of complications such as anastomotic strictures and leaks by allowing for precise, endoscopic formation of anastomoses without external incisions, potentially lowering morbidity and mortality, and facilitating gastric remodeling for metabolic disorders.

Implementation Method 1

a first vacuum channel, a first compartment, a first end and a second end, with the first vacuum channel and the first compartment extending to the second end of the outer tubular member. A first vacuum port that is capable of being operatively connected to a vacuum source may further be coupled with the outer tubular member

AI summary

A device and system are described that are capable of isolating at least one targeted tissue and forming an anastomosis between two internal body structures though a completely endoscopic procedure. Further, the device and system described generally comprise two tubular members that are capable of moving in a telescopic fashion relative to one another. Additionally, a method is described for using the device and/or system to bypass the duodenum from digestion.
