Find Innovative SolutionsGenerate Solutions

Solution Overview

Problem

Current surgical methods for gallbladder disease, such as open surgical resection and endoscopic approaches, are invasive and carry risks like bleeding, infection, and post-operative pain, with a need for a more minimally invasive technique to create anastomosis between gastrointestinal organs.

Innovation Solution

The use of a parent magnet and daughter magnets to create a magnetic field, allowing for the attraction and compression of adjacent organ walls, facilitating the formation of a fistula or anastomosis between organs like the gallbladder and stomach or small intestine, using endoscopic instruments and visualization technologies.

Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Reliability

If open surgical resection or endoscopic approaches are used to treat gallbladder disease, then the disease can be treated, but the patient is exposed to surgical risks such as bleeding, infection, and post-operative pain

Engineering Contradiction:

Improvedisease treatment effectivenessVSAvoidsurgical risks including bleeding, infection, and post-operative pain

Core Design Contradiction:

ReliabilityVSObject-affected harmful factors

Solution Approach 1:

The patent replaces traditional mechanical surgical instruments and incisions with a magnetic field-based system. Parent and daughter magnets are positioned in adjacent organs to create magnetic compression that induces tissue necrosis and forms an anastomosis, eliminating the need for physical incisions and reducing surgical trauma

Inventive Principle:

Principle #28Mechanics substitution (Replace mechanical system)

Solution Approach 2:

The patent introduces magnetic fields as an intermediary mechanism to achieve tissue connection. Instead of directly suturing or stapling organs together, magnetic compression is used as an intermediate process to induce controlled necrosis and spontaneous anastomosis formation, reducing direct mechanical trauma

Inventive Principle:

Principle #24Intermediary (Mediator)

2Reliability

If traditional surgical methods are used to create anastomosis between gastrointestinal organs, then the connection can be established, but significant tissue damage and long recovery time occur

Engineering Contradiction:

Improveanastomosis formationVSAvoidrecovery time

Core Design Contradiction:

ReliabilityVSLoss of time

Solution Approach 1:

The patent replaces mechanical suturing and stapling with magnetic compression. The parent and daughter magnets create sustained compressive force that guides tissue healing and anastomosis formation over time, reducing the need for invasive mechanical intervention and subsequent recovery

Inventive Principle:

Principle #28Mechanics substitution (Replace mechanical system)

3Reliability

If invasive surgical techniques are used to create openings between organs, then the connection can be established, but the risk of complications such as perforation and adhesions increases

Engineering Contradiction:

Improveanastomosis creationVSAvoidcomplications including perforation and adhesions

Core Design Contradiction:

ReliabilityVSObject-generated harmful factors

Solution Approach 1:

The patent uses magnetic fields as an intermediary to achieve tissue connection without direct mechanical contact or incisions. The magnetic compression induces controlled necrosis and spontaneous anastomosis formation, eliminating the harmful effects of surgical incisions such as perforation risk and adhesion formation

Inventive Principle:

Principle #24Intermediary (Mediator)

Solution Approach 2:

The patent replaces mechanical cutting, suturing, and stapling with a magnetic field-based compression system. This substitution eliminates the mechanical trauma that causes complications like perforation and adhesions while still achieving reliable anastomosis formation

Inventive Principle:

Principle #28Mechanics substitution (Replace mechanical system)

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 method enables the creation of a minimally invasive anastomosis, reducing tissue damage and recovery time, while avoiding traditional surgical risks, by using magnetic forces to induce necrosis and form a functional opening between organs.

Implementation Method 1

The parent magnet can include a magnetic portion adapted to generate a magnetic field

Methodology Applied

Scientific EffectMagnetic field: Magnetic Field

Implementation Method 2

The daughter magnets or magnetic materials are responsive to the magnetic field of the parent magnet so as to be attracted to the parent magnet through one or more tissues of varying degrees of thickness

Methodology Applied

Scientific EffectMagnetic attraction: Magnetism

AI summary

Methods and apparatus for creating an anastomosis or fistula between the gallbladder and an adjacent organ are disclosed. First, a parent magnet, typically a permanent magnet, is deployed in the stomach, small intestine, or another organ adjacent to the gallbladder, and a mating daughter material is deployed in the gallbladder in order to create a magnet-compression anastomosis. The gallbladder may then be ablated or otherwise functionally inactivated through the anastomosis. Another aspect of the invention relates to an all-in-one surgical kit that contains all the necessary specialized tools for a surgeon to perform the procedure.
