Hemostasis valve system
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing hemostasis valves do not effectively accommodate the passage of multiple elongate medical devices while maintaining hemostasis, and existing documents do not disclose the combination of a seal anchor member with a valve bypass portion and an elongate member with a side opening.
Innovation Solution
A hemostasis valve system with a valve member featuring multiple sealable openings and slits, allowing passage of multiple elongate medical devices, and a valve bypass portion for coupling with a medical device, ensuring hemostasis and fluid communication.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Adaptability or versatility
If a traditional hemostasis valve is used, then hemostasis is maintained, but only one elongate medical device can pass through simultaneously
Solution Approach 1:
The valve member is divided into multiple independent sealable openings (first sealable opening and second sealable opening), each capable of sealing around separate elongate medical devices. This segmentation allows multiple devices to pass through simultaneously while maintaining hemostasis at each opening independently.
Solution Approach 2:
The valve member includes a third dimension by incorporating a valve bypass portion that extends through the valve body, providing an additional pathway for fluid communication while maintaining the sealing function of the traditional valve openings.
2Adaptability or versatility
If a valve bypass portion is added to couple with a medical device, then fluid communication is enabled, but device complexity increases
Solution Approach 1:
The valve bypass portion is merged with the existing valve member structure, combining the bypass function with the traditional valve body. This integration allows fluid communication through the bypass portion while maintaining compatibility with existing medical device coupling mechanisms, reducing overall system complexity.
Solution Approach 2:
The valve bypass portion is designed to serve multiple functions: providing fluid communication pathways, coupling with various medical devices, and maintaining hemostasis. This multi-functionality reduces the need for separate components, thereby reducing device complexity.
3Adaptability or versatility
If multiple sealable openings are provided in the valve member, then multiple medical devices can pass through, but manufacturing precision requirements increase
Solution Approach 1:
The valve member is segmented into multiple independent sealable openings, each with its own sealing mechanism. This segmentation allows for standardized manufacturing of each opening while maintaining overall precision through consistent sealing designs, reducing the cumulative precision requirements.
Solution Approach 2:
The sealing mechanism utilizes elastic deformation of the valve member material around each sealable opening to achieve sealing. By relying on elastic parameters rather than precise mechanical fits, the design reduces manufacturing precision requirements while maintaining effective sealing across multiple openings.

AI summary
Hemostasis valves and hemostasis valve systems are provided. A hemostasis valve can include a valve member, wherein the valve member includes a first sealable opening disposed through a first portion of the valve member and a second sealable opening disposed through a second portion of the valve member. The valve member may also include three or more sealable openings. A hemostasis valve system may include a hemostasis valve and another medical device. The hemostasis valve may be releasably coupleable to the other medical device.
