Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Current microcatheters and micro-guide wires lack signal transmission and electric energy capabilities, limiting their practicality and requiring additional auxiliary means for real-time position feedback and operation, which increases the workload for medical personnel and complicates minimally invasive intervention procedures.
Innovation Solution
The integration of a multi-layer structure within the microcatheter and micro-guide wire, including an inner tube layer, an intermediate layer formed by winding conducting wires for signal and energy transmission, and an outer layer for protection, enabling the microcatheter and micro-guide wire to transmit signals and electric energy, thereby enhancing their functionality and reducing operational complexity.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Loss of information
If conducting wires are integrated into the intermediate layer of the microcatheter, then signal transmission capability is improved, but device structure complexity increases
Solution Approach 1:
The patent integrates conducting wires directly into the intermediate layer of the microcatheter structure, merging the signal transmission function with the existing structural layer. This combination eliminates the need for separate signal transmission components and reduces overall device complexity despite adding functionality.
Solution Approach 2:
The intermediate layer is designed to serve multiple functions: providing structural support and simultaneously transmitting signals through embedded conducting wires. This multi-functionality reduces the need for additional dedicated components, thereby managing complexity while improving signal transmission capability.
2Use of energy by moving object
If multiple line bodies are embedded in the intermediate layer, then electric energy transmission capability is improved, but manufacturing complexity increases
Solution Approach 1:
The intermediate layer is divided into multiple segments or zones, each containing specific conducting wires for different energy transmission purposes. This segmentation allows for modular manufacturing approaches, where each segment can be prepared and integrated systematically, reducing overall manufacturing complexity despite multiple energy transmission lines.
Solution Approach 2:
The intermediate layer uses composite material construction combining conductive and insulating materials in a structured arrangement. This composite approach enables multiple line bodies to be embedded while maintaining electrical isolation and structural integrity, facilitating a more manageable manufacturing process.
3Adaptability or versatility
If the microcatheter structure is enhanced with conducting wires, then functionality is improved, but device diameter increases
Solution Approach 1:
The conducting wires are nested within the intermediate layer of the microcatheter, with insulation layers and shielding structures arranged concentrically. This nested configuration allows multiple functional elements to occupy the same radial space, enhancing functionality without significantly increasing the overall device diameter.
Solution Approach 2:
Instead of adding conducting wires radially outward which would increase diameter, the patent arranges them azimuthally within the intermediate layer thickness. This dimensional reorganization places signal and power transmission elements in the angular dimension rather than the radial dimension, preserving the compact diameter while improving functionality.
