Hemostasis Valves With Multiple Sealable Openings
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Current hemostasis valves are limited in their ability to accommodate multiple elongate medical devices simultaneously, particularly in procedures requiring access and treatment of two or more vessels, as they typically have only one sealable opening, which restricts the passage of different-sized medical instruments.
Innovation Solution
The development of hemostasis valves with multiple sealable openings, including at least two or more slits and cap openings, allowing for the passage of multiple elongate medical devices while maintaining hemostasis, with resilient materials and configurations that adapt to different device profiles and sizes.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Adaptability or versatility
If a hemostasis valve has only one sealable opening, then the valve structure remains simple and easy to manufacture, but it cannot accommodate multiple elongate medical devices simultaneously
Solution Approach 1:
The valve member is segmented into multiple sealable openings (first sealable opening, second sealable opening, etc.) instead of a single opening. Each opening can independently seal around different medical devices, allowing simultaneous accommodation of multiple devices while maintaining hemostasis. This segmentation directly resolves the contradiction by enabling multi-device capability without requiring complete redesign of the entire valve system.
Solution Approach 2:
The valve member is designed with multiple sealable openings that can universally accommodate various sizes and types of elongate medical devices. The resilient material and configurable seal mechanism provide multi-functional capability, allowing the same valve to seal around different devices (catheters, guidewires, sheaths) of varying profiles and diameters, thereby improving adaptability without proportionally increasing complexity.
2Productivity
If a hemostasis valve has multiple sealable openings, then it can pass multiple medical devices simultaneously, but the valve structure becomes more complex
Solution Approach 1:
The valve member is divided into multiple independent sealable openings, each capable of simultaneously sealing around different medical devices. This segmentation enables procedural efficiency by allowing multiple devices to pass through the valve at the same time without requiring sequential operations, directly addressing the productivity improvement while maintaining manageable structural complexity through modular design.
Solution Approach 2:
The valve member incorporates resilient materials and configurable seal mechanisms that dynamically adapt to different device profiles and sizes. This dynamic capability allows the valve to maintain hemostasis across multiple openings with varying dimensions, enabling simultaneous passage of multiple devices of different types without requiring rigid, overly complex structural designs.
3Reliability
If the valve uses resilient materials to adapt to different device profiles, then it provides secure sealing, but the material selection and configuration become more complex
Solution Approach 1:
The valve member utilizes resilient materials with specific elastic properties that allow the sealable openings to dynamically change shape and size to accommodate different medical device profiles. By selecting materials with appropriate elasticity parameters, the valve provides reliable sealing across multiple openings without requiring complex mechanical adjustment mechanisms, thereby maintaining ease of manufacture while ensuring sealing reliability.
Solution Approach 2:
The valve member may incorporate composite material structures combining resilient sealing components with supportive structural elements. This composite approach enables the valve to provide secure sealing around multiple devices of varying profiles while maintaining structural integrity, balancing material complexity with manufacturing feasibility through integrated design.

Function Achieved in This Case
Enables the simultaneous or sequential passage of multiple medical devices through the valve, enhancing procedural efficiency and versatility by providing a secure seal for various medical instruments, reducing the risk of device interaction and improving access to multiple vessels.
Implementation Method 1
The valve member may include 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
