Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If traditional single-function dilatation catheters are used, then the device structure is simple, but multiple devices need to be inserted into the blood vessel to achieve different functions, increasing harm to patients and affecting surgical safety
Solution Approach 1:
The patent applies multi-functionality by integrating multiple guidewire channels (first, second, and third channels) into a single catheter structure. The first channel extends through the balloon for guiding, the second channel is located at the distal end for cutting, and the third channel is at the proximal end for anchoring. This allows one catheter to perform multiple functions (guiding, cutting, anchoring) that previously required separate devices, thereby reducing the number of insertions into the blood vessel and improving surgical safety without significantly increasing structural complexity
2Productivity
If multiple traditional single-function catheters are used to achieve different functions, then each function can be performed, but the number of devices in the blood vessel increases, reducing surgical efficiency and increasing patient harm
Solution Approach 1:
The patent merges multiple functional channels into a single catheter device. The first guidewire channel, second guidewire channel, and third guidewire channel are combined within one catheter structure, allowing guiding, cutting, and anchoring functions to be performed simultaneously or sequentially with a single device insertion. This consolidation reduces the quantity of devices in the blood vessel from multiple separate catheters to one multi-functional catheter, thereby improving surgical efficiency and reducing patient harm
3Ease of operation
If traditional single-function catheters are used, then the device design is simple, but the use effect is poor due to the need for multiple insertions and coordinated operations
Solution Approach 1:
The patent improves ease of operation by providing a multi-functional catheter where the first, second, and third guidewire channels can be used independently or in combination for different surgical needs. The proximal end communication with the guidewire exchange port allows easy access for guidewire insertion and manipulation. This integrated design eliminates the need to coordinate multiple separate catheters, simplifying the surgical workflow and improving the use effect while maintaining reasonable structural complexity

AI summary
Disclosed are a multi-guidewire balloon dilatation catheter structure, a dilatation catheter mechanism and a medical device. The multi-guidewire balloon dilatation catheter comprises a balloon, a first guidewire channel, a second guidewire channel and a third guidewire channel. The first guidewire channel is at least partially passed through the balloon. The second guidewire channel is at least partially located at the distal end of the balloon. The third guidewire channel is at least partially located at the proximal end of the balloon. In the multi-guidewire balloon dilatation catheter structure of this embodiment, each guidewire channel can be used for accommodating the guidewire by providing the first guidewire channel and the second/third guidewire channel to assemble various devices on the single catheter of the present invention, thereby realizing simultaneous execution of device guidance, plaque cutting, guidewire anchoring, etc. The structure is simple and good in use effect.
