Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Current tissue separation methods fail to effectively protect healthy tissues from the harmful effects of treatments like radiation and chemical therapies, as they either lack the necessary shape for effective protection or cause significant physiological impact during displacement.
Innovation Solution
A tissue displacement/separation device comprising an expandable bladder that can be positioned between tissues to displace one tissue from another, using various shapes and materials to minimize pressure and damage, and can be filled with fluid or expanded using a coiled element, providing thermal insulation and radiation shielding.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Object-affected harmful factors
If a porous flexible sheet or tube is used for tissue separation, then cells and tissue particles are restricted, but radiation energy and chemical agents still penetrate through the pores
Solution Approach 1:
The patent employs a flexible balloon or membrane structure that can be positioned between healthy and pathological tissues. This flexible shell creates a physical barrier that maintains tissue separation while allowing the device to conform to anatomical spaces, solving the limitation of rigid porous sheets that failed to block radiation and chemicals effectively.
Solution Approach 2:
The device introduces a fluid medium (such as saline or contrast agent) as an intermediary substance between the tissues. This fluid fills the separation space and provides both mechanical displacement and radiological contrast, enabling effective tissue separation while blocking harmful factors without compromising the separation's reliability.
2Stability of the object's composition
If mechanical separators or fluid infusion is used to separate tissues, then thermal insulation is provided, but the device cannot uniformly displace tissue or maintain stable shape
Solution Approach 1:
The patent utilizes a dynamically adjustable balloon that can be inflated to varying degrees to achieve uniform tissue displacement. The balloon's expandable nature allows it to adapt to different anatomical configurations and apply consistent pressure across the tissue interface, maintaining stable separation and thermal insulation throughout the treatment procedure.
Solution Approach 2:
The device changes its physical parameters (volume, pressure, shape) by controlling fluid infusion into the balloon. This parameter adjustment enables the balloon to maintain optimal contact with tissues, provide uniform displacement, and sustain stable thermal insulation barriers during treatment, preventing harmful thermal exposure to healthy tissues.
3Productivity
If high radiation or chemical dose is applied to pathological tissue, then treatment effectiveness increases, but healthy adjacent tissues receive harmful exposure
Solution Approach 1:
The patent segments the treatment field by physically separating healthy and pathological tissues using the balloon device. This segmentation creates distinct zones where different doses can be applied - high dose to the pathological tissue and low or zero dose to the healthy tissue, thereby increasing treatment efficiency while minimizing harmful exposure to healthy adjacent tissues.
