Magnetic Cells for Dynamic Pipe Shape Control
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Current stents used to treat vascular and respiratory issues are incompatible across different organs and can cause foreign body sensations, immune rejection, and are not optimally controlled for shape, leading to inefficiencies in treating stenosis and other diseases.
Innovation Solution
A magnetic cell system using a magnetic material to control the shape of biological pipes with fluid flow, such as blood vessels and respiratory tracts, through repulsive or attractive forces, produced using autologous cells and optimized by artificial intelligence for injection site, amount, and method, with near-infrared irradiation for enhanced treatment.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If a stent is inserted to expand a stenosis site in a blood vessel, then the lumen of the blood vessel is secured, but intimal injury occurs and in-stent restenosis may occur due to vascular muscle cell overgrowth
Solution Approach 1:
The patent replaces the mechanical stent structure with a magnetic field-based control system. Magnetic cells are introduced into the blood vessel and controlled by external magnetic fields to expand the vessel lumen, eliminating the need for permanent mechanical implants that cause intimal injury and restenosis.
Solution Approach 2:
The patent changes the physical state and properties of cells through magnetic field application. By controlling magnetic cell parameters (position, concentration, magnetic moment) through external fields, the system achieves dynamic vessel expansion without the harmful effects of permanent mechanical stents.
2Ease of operation
If a stent is inserted in a urethra to improve dysuria and urethrophraxis, then the urinary flow is improved, but the stent slides during urination, causes foreign body sensation, and has a narrow tube lumen that is easily clogged
Solution Approach 1:
The patent replaces the permanent mechanical urethral stent with a magnetic cell-based system. Magnetic cells are introduced and controlled by external magnetic fields to maintain urethral patency during urination, eliminating foreign body sensations and clogging issues associated with fixed mechanical structures.
Solution Approach 2:
The patent creates a dynamic system where magnetic cells can be repositioned and controlled in real-time during urination. The magnetic field can adjust cell distribution to maintain optimal urethral shape during different urinary flow conditions, preventing sliding and clogging.
3Reliability
If a positive pressure machine is used to treat obstructive sleep apnea by blowing air to increase pressure in the respiratory tract, then breathing is maintained, but constant wear causes complications such as pneumonia, dry nasal passages, and muscle pain
Solution Approach 1:
The patent replaces the external mechanical positive pressure machine with an internal magnetic cell-based system. Magnetic cells are introduced into the respiratory tract and controlled by external magnetic fields to maintain airway patency from within, eliminating the need for constant external machine wear and its associated complications.
4Manufacturing precision
If stents are individually manufactured depending on the size and nature of organs in which they are installed, then the stent fits the specific organ, but the stents are incompatible across different organs and lumens
Solution Approach 1:
The patent creates a universal magnetic cell system that can be applied across different organs and lumens. The same magnetic cells can be controlled by adjusting external magnetic field parameters to adapt to different organ sizes and shapes, eliminating the need for organ-specific manufacturing while maintaining precise fit.
