Elastic Occlusion Device Withstands Peristaltic Waves
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing reversible occlusion devices for biological tubes, such as the vas deferens, often fail to withstand peristaltic wave contractions, leading to ineffective contraception and difficulties in reversing the procedure without damaging the tissue, with many methods requiring invasive surgery and resulting in unsuccessful reconnection of the reproductive system.
Innovation Solution
An occlusion device comprising at least two sections connected by narrowings, made of elastic material, designed to deform and absorb peristaltic wave forces, ensuring the device remains in place during contractions and allowing for reversible insertion and removal without tissue damage, by matching the length of the sections to the wavelength of the peristaltic wave and using biocompatible materials for compatibility and ease of use.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If a blocking element is inserted into the biological tube to prevent spermatozoes from entering the seminal vesicles, then contraception effectiveness is improved, but the device is pushed out by peristaltic wave contractions
Solution Approach 1:
The occlusion device is divided into multiple sections (first section, second section, third section) connected by narrowings. This segmentation allows the device to flex and deform under peristaltic wave forces while maintaining overall occlusion, preventing the device from being pushed out while blocking sperm transport effectively
Solution Approach 2:
The device is designed to be deformable rather than rigid, allowing it to dynamically respond to peristaltic wave contractions. The sections can compress and the narrowings can flex during wave passage, enabling the device to withstand physiological forces while maintaining its occlusive function
2Reliability
If surgery is performed to cut and tie off the vas deferens to achieve sterilisation, then contraception effectiveness is improved, but the procedure becomes irreversible and tissue damage occurs
Solution Approach 1:
Instead of permanently altering the biological tube through cutting and tying, the invention extracts the occlusion function into a separate removable device that is inserted into the tube. This allows the biological tube to remain intact and reversible, while still achieving effective contraception when the device is in place
3Reliability
If the occlusion device is made rigid to maintain its blocking function, then contraception effectiveness is improved, but the device cannot withstand peristaltic wave forces
Solution Approach 1:
The occlusion device employs a flexible structure with sections and narrowings that can deform under physiological forces. This flexibility allows the device to withstand peristaltic wave contractions while maintaining its occlusive function, combining the benefits of rigidity for blocking with flexibility for force resistance
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
The device effectively withstands peristaltic wave contractions, maintaining its position within the biological tube and allowing for easy removal without damaging the tissue, enhancing the chances of successful reversal of contraception and reducing surgical intervention risks.
Implementation Method 1
The occlusion device is of an elastic material, and each section is configured to deform in accordance with a force applied by the peristaltic wave
Implementation Method 2
each section is configured to deform in accordance with a force applied by the peristaltic wave, so as to absorb the peristaltic wave
Implementation Method 3
the biological tube being prone to a peristaltic wave having a wave length... the forces of transportation created by the peristaltic wave contractions of the biological tube

AI summary
The present methods, systems, and devices relate to an occlusion device for blocking a biological tube, the biological tube being prone to a peristaltic wave having a wave length, and where the occlusion device comprises at least two sections, where each section is connected by at least one narrowing to at least one other section. The occlusion device is of an elastic material, and each section is configured to deform when a force is applied by the peristaltic wave, and the length of at least one of the at least two sections corresponds substantially to the wave length of the peristaltic wave in the biological tube, so as to absorb the peristaltic wave. The methods, systems, and devices relates to reversible contraception of female and/or male gendered species intervening with biological tube, which are responsible for transportation of fertility fluids, such as the transportation of spermatozoes or oocytes in for example the human reproductive system.
