Solution Overview
Problem
Conventional catheters face challenges in precisely delivering contrast or therapeutic agents due to the need for a large diameter to accommodate various tools, leading to potential overuse or misplacement of these agents within the body.
Innovation Solution
A boosting catheter system comprising a distal tube and a proximal shaft with a lumen, allowing for controlled fluid delivery and enhanced flexibility to extend beyond the guiding catheter, facilitating precise placement and minimization of agent usage.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Adaptability or versatility
If the guiding catheter diameter is increased to accommodate various tools and devices, then the versatility and adaptability of the catheter system is improved, but the precision and control over fluid delivery is worsened due to potential overuse or misplacement of agents
Solution Approach 1:
The catheter system is divided into two separate components: a guiding catheter for tool accommodation and a boosting catheter for precise fluid delivery. The boosting catheter can be selectively positioned within the guiding catheter to deliver fluids at specific target locations, thereby segmenting the functions of tool access and fluid delivery to resolve the contradiction between versatility and precision.
Solution Approach 2:
The boosting catheter acts as an intermediary device between the guiding catheter and the target vascular location. It is inserted through the guiding catheter and extends to the desired target, serving as a mediator that enables precise fluid delivery without requiring the guiding catheter to have a smaller diameter, thus maintaining both versatility and precision.
2Ease of operation
If the guiding catheter diameter is maintained large to accommodate tools, then the ease of operation for tool insertion is improved, but the quantity of contrast or therapeutic solution that can be safely introduced is worsened due to risk of overuse
Solution Approach 1:
The system separates the functions of tool access and fluid delivery into different catheters. The guiding catheter maintains its large diameter for easy tool insertion, while the boosting catheter provides controlled fluid delivery pathways that limit the quantity of contrast or therapeutic solution introduced, preventing overuse while maintaining operational ease.
Solution Approach 2:
The boosting catheter system incorporates feedback mechanisms through controlled delivery pathways and monitoring that allow real-time adjustment of fluid introduction. This feedback control ensures that the quantity of contrast or therapeutic solution remains within safe limits while maintaining the ease of tool insertion through the guiding catheter.
3Device complexity
If the guiding catheter is used for both tool access and fluid delivery, then the device complexity is reduced, but the manufacturing precision and control over fluid delivery location is worsened
Solution Approach 1:
The catheter system is segmented into a guiding catheter for tool access and a boosting catheter for precise fluid delivery. The boosting catheter is designed with specific lumens and positioning capabilities that enable precise control over fluid delivery location, thereby improving manufacturing precision while the modular design keeps overall system complexity manageable.
Solution Approach 2:
The boosting catheter is nested within the guiding catheter, with the boosting catheter's lumens positioned to communicate with the target vascular location. This nested configuration allows precise fluid delivery control while maintaining a relatively simple overall device architecture, as the boosting catheter fits within the existing guiding catheter structure.
