Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Conventional balloon catheter inflation and deflation systems lack effective mechanisms to handle abnormalities such as balloon rupture or displacement during procedures, potentially causing damage to the patient's lumen.
Innovation Solution
An indeflation system that includes a control unit to acquire medical images of the balloon, detect abnormalities using image analysis, and automatically depressurize the balloon if an abnormality is detected, utilizing a pump and pressure sensor to manage fluid pressure and movement within the catheter.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If manual or power drive pressurization is used for balloon inflation, then the balloon can be inflated and deflated, but the system cannot automatically detect or respond to balloon abnormalities such as rupture or displacement
Solution Approach 1:
The system continuously acquires medical images during balloon inflation and feeds back the balloon position and state information to the control unit. This feedback mechanism enables automatic detection of abnormalities such as balloon rupture or displacement, allowing the system to respond by stopping inflation or initiating deflation, thereby improving reliability without requiring overly complex manual monitoring systems
Solution Approach 2:
The balloon catheter system performs self-diagnosis by automatically detecting its own abnormalities through medical image acquisition and analysis. The control unit monitors the balloon's position and state in real-time, enabling the system to self-identify issues such as rupture or displacement and automatically take corrective actions, reducing the need for external intervention while maintaining system reliability
2Productivity
If the balloon is pressurized to perform the procedure, then the therapeutic effect is achieved, but the risk of lumen damage increases if an abnormality occurs
Solution Approach 1:
The system acquires medical images before balloon inflation to establish the baseline position and state of the balloon and surrounding lumen structures. This preliminary action allows the system to compare post-inflation images against the baseline, enabling early detection of abnormalities such as balloon displacement or rupture before they cause lumen damage, thus maintaining procedural effectiveness while reducing harm
Solution Approach 2:
The control unit is pre-programmed with safety thresholds and response protocols for detecting balloon abnormalities. When abnormalities such as rupture or displacement are detected during inflation, the system automatically stops inflation or initiates deflation procedures, providing a cushioning effect that prevents further potential damage to the lumen while maintaining the therapeutic benefits of the pressurization
3Measurement precision
If medical image acquisition is performed continuously to monitor balloon position, then abnormality detection accuracy is improved, but the system complexity and processing load increase
Solution Approach 1:
The system acquires medical images at key stages (before inflation, during inflation, and after inflation) rather than continuously throughout the entire procedure. This partial action approach maintains sufficient detection accuracy for identifying balloon abnormalities such as rupture or displacement while significantly reducing the processing load and system complexity compared to continuous real-time imaging
Solution Approach 2:
The image acquisition and analysis process is segmented into distinct phases: pre-inflation baseline imaging, intra-inflation monitoring at critical pressure points, and post-inflation verification. Each phase has specific imaging requirements and analysis focus, allowing the system to maintain high detection precision for balloon abnormalities while managing computational complexity through phased processing rather than uniform continuous operation

AI summary
An indeflation system includes a control unit configured to control an operation of a pump configured to pressurize or depressurize an inside of a catheter at a distal portion of which a balloon is provided, in which the control unit acquires a medical image of the balloon provided at the distal portion of the catheter inserted into a lumen, the balloon pressurized by the pump, detects presence or absence of an abnormality of the balloon on the basis of the medical image of the pressurized balloon, and controls the pump so as to depressurize the balloon in a case where the abnormality of the balloon is detected.
