Catheter System for Bifurcated Lesion Treatment
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Current diagnostic methods for treating bifurcated blood vessels lack a systematic approach to determine which lesion to treat first, leading to inefficiencies in intervention procedures, increased patient burden, and higher medical costs due to longer operation times and the need for multiple catheters.
Innovation Solution
A method using electromagnetic waves, such as X-rays, to determine the vessel diameter of lesions and employing artificial intelligence through machine-learning and reinforcement-learning to prioritize the treatment of larger vessel diameter lesions first, thereby optimizing catheter usage and reducing procedure time.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If multiple catheters are used to treat lesions in bifurcated blood vessels, then treatment coverage is improved, but device complexity and patient burden increase
Solution Approach 1:
The guiding catheter is designed with a distal end that can access both bifurcated blood vessels simultaneously, enabling a single catheter to perform multiple treatment functions in different vascular locations, thereby reducing the total number of catheters needed while maintaining comprehensive treatment coverage
Solution Approach 2:
The catheter system employs a nested structure where additional catheters or treatment devices can be advanced through the guiding catheter to reach specific lesions, allowing sequential access to multiple bifurcated vessels through a single access point and reducing the number of separate catheter insertions required
2Productivity
If treatment order is not optimized, then procedure flexibility is maintained, but operation time increases
Solution Approach 1:
The system performs preliminary diagnostic imaging and lesion characterization before treatment begins, allowing the treatment plan and catheter routing strategy to be predetermined, which optimizes the treatment sequence and reduces actual intervention time while maintaining flexibility for intra-procedural adjustments
Solution Approach 2:
The system incorporates real-time imaging and diagnostic feedback during the procedure to monitor catheter position and treatment progress, enabling dynamic adjustment of treatment sequence and strategy based on actual anatomical findings and treatment response, thus maintaining flexibility while optimizing efficiency
3Productivity
If diagnostic methods do not prioritize treatment sequence, then diagnostic simplicity is maintained, but treatment efficiency decreases
Solution Approach 1:
The diagnostic process is segmented into distinct analytical components including individual lesion characterization, vessel diameter measurement, and automated treatment sequence generation, allowing each component to be processed independently and systematically, thereby improving treatment efficiency while maintaining diagnostic clarity and interpretability
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
This approach reduces patient burden, shortens treatment time, and lowers medical costs by ensuring the most effective treatment of larger vessel diameter lesions first, followed by smaller ones, using a single catheter assembly and minimizing the number of catheters required.
Implementation Method 1
detecting electromagnetic waves obtained through a patient by irradiating the patient with electromagnetic waves, and obtaining electromagnetic wave information on the patient based on a changed electromagnetic wave

AI summary
A method for diagnosing, validation of diagnosis and treating a patient having lesions in both arteries of left and right lower limbs. By determining that a larger vessel diameter lesion to be treated first, catheters and an operation time can be reduced is to be treated first on a priority basis based on diagnostic data, deciding that a smaller vessel diameter lesion is to be treated next, then treating the lesions substantially continuously.
