Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Current methods lack a quantifiable way to determine the percentage opening of lumen diameter post-balloon angioplasty and rely on physician expertise for pressure application, risking vessel damage from over-inflation or under-expansion.
Innovation Solution
A method using medical imaging and image processing to determine occlusion characteristics, such as size, thickness, and composition, to calculate the optimal inflation pressure for occlusion devices, preventing damage by simulating lumen diameter expansion and applying radial pressure based on material properties.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of operation
If physician expertise is used to determine pressure application, then the procedure can be performed, but the determination is error-prone and time-consuming
Solution Approach 1:
The patent replaces the physician's manual pressure determination with an automated image processing system that analyzes medical images to calculate optimal inflation pressure based on occlusion characteristics, eliminating human error and time consumption while improving precision
Solution Approach 2:
The system automatically determines pressure parameters by processing medical images and analyzing occlusion characteristics, allowing the procedure to self-determine optimal pressure without requiring physician expertise or manual intervention
2Productivity
If pressure is applied to inflate occlusion device, then lumen expansion is achieved, but vessel damage may occur from over-inflation
Solution Approach 1:
The system performs preliminary analysis of medical images to determine optimal inflation pressure before the actual procedure, allowing the physician to apply pressure with confidence that it is both sufficient for expansion and safe to avoid vessel damage
Solution Approach 2:
The system provides feedback by calculating and communicating the optimal pressure value to the physician based on analyzed occlusion characteristics, enabling informed decision-making during pressure application to balance expansion efficiency with safety
3Object-affected harmful factors
If pressure is applied to inflate occlusion device, then lumen expansion is achieved, but under-inflation may not allow efficient expansion
Solution Approach 1:
The system performs preliminary calculation of the optimal pressure value based on image analysis of occlusion characteristics, ensuring that the pressure applied is sufficient to achieve efficient lumen expansion without wasting excessive pressure
Solution Approach 2:
The system changes the pressure parameter by calculating an optimal value specific to each patient's occlusion characteristics, ensuring that the pressure applied is both sufficient for expansion and minimized to avoid unnecessary stress
