Deflation Catheter Stylet Control and Suction Integration
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing catheter devices for deflating implantable balloon systems lack control mechanisms for safe and efficient puncture and aspiration of multiple balloons, often requiring tool removal and reconnecting suction tubing, which can lead to accidental exposure of the needle and inefficient operation.
Innovation Solution
A deflation catheter device with a stylet and handle system that allows controlled advancement, retraction, and rotation of the needle tip, combined with a suction port for fluid communication, enabling puncture and aspiration of multiple balloons without tool removal or reconnecting suction tubing, and featuring a seal to prevent leaks and a threaded interface for precise control.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of operation
If existing catheter devices are used for deflating multiple balloons, then the deflation function can be performed, but the needle tip requires removal and reconnecting of suction tubing between uses, leading to accidental exposure and inefficiency
Solution Approach 1:
The patent combines the stylet (needle) and suction tubing into a single integrated deflation catheter device. The stylet is permanently attached to the catheter tube, and the suction tubing is connected to a suction port on the handle, eliminating the need to remove or reconnect components between balloon deflations. This merging of components directly resolves the technical contradiction by enabling continuous operation without tool removal or reconnecting.
Solution Approach 2:
The deflation catheter device is designed as a multi-functional tool that can deflate multiple balloons sequentially without requiring component changes. The single device performs puncture, aspiration, and deflation functions across multiple balloons, making it a universal solution that eliminates the need for separate tools or reconnections for each balloon, thereby improving ease of operation and reducing time loss.
2Reliability
If existing catheter devices are used for deflating multiple balloons, then the deflation function can be performed, but the needle tip requires removal and reconnecting of suction tubing between uses, leading to accidental exposure
Solution Approach 1:
The stylet is permanently integrated into the catheter tube structure, eliminating the risk of accidental exposure that occurs when needles are removed and reconnected. The suction tubing is also permanently connected to the handle, ensuring continuous fluid communication without disconnection. This permanent integration directly improves safety while maintaining ease of operation.
Solution Approach 2:
The handle includes a seal that prevents fluid leakage when the stylet is in the retracted position within the catheter tube. This preliminary protective measure ensures that even when the stylet is not actively puncturing, the system remains safe and leak-free, preventing accidental exposure and maintaining reliability throughout the entire operation cycle.
3Productivity
If existing catheter devices are used for deflating multiple balloons, then the deflation function can be performed, but tool removal and reconnecting is required, leading to inefficient operation
Solution Approach 1:
By merging the stylet, catheter tube, and suction tubing into a single integrated device, the system eliminates the need for multiple tool changes and reconnections. This consolidation improves productivity by enabling continuous operation across multiple balloons while the overall device remains relatively simple in structure, with the complexity distributed across integrated components rather than multiple separate tools.
4Reliability
If a seal is added between the catheter tube and handle to prevent leaks, then reliability is improved, but device complexity increases
Solution Approach 1:
The seal is integrated into the handle structure as a built-in component rather than an external add-on. This integration allows the seal to be part of the standard device assembly, improving reliability through leak prevention while minimizing the increase in device complexity by incorporating the sealing function into the existing handle design rather than adding separate complex sealing mechanisms.
