Rotating Luer Lock Hemostasis Valve for Guide Catheter Control
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Current catheter systems face challenges in efficiently controlling guide catheters during vascular procedures, particularly in positioning and rotating them accurately within the patient's arterial system, which can lead to inefficiencies and complications.
Innovation Solution
A hemostasis valve system with a rotating male luer lock connector and a drive mechanism that allows for precise control of guide catheters, enabling rotational and linear movement, is integrated into a robotic catheter system. This system includes a valve body with a first and second leg, where the second leg extends at an angle for fluid communication and is secured by a rotating male luer lock connector, allowing for secure attachment and precise manipulation of guide catheters.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Measurement precision
If a traditional hemostasis valve is used without rotational control, then the structure is simple, but the guide catheter cannot be precisely positioned or rotated within the arterial system
Solution Approach 1:
The patent combines the hemostasis valve with a rotating connector into a single integrated assembly. The rotating male luer lock connector is directly coupled to the valve body, allowing rotational control of the guide catheter while maintaining hemostatic function. This merging eliminates the need for separate rotational control mechanisms, achieving precise positioning without proportionally increasing overall system complexity.
Solution Approach 2:
The rotating male luer lock connector serves multiple functions: it provides hemostatic sealing like a traditional valve, enables rotational control of the guide catheter, and maintains fluid communication. This multi-functionality allows a single component to address both the need for precise positioning and the requirement for structural simplicity.
2Measurement precision
If manual control of guide catheter is used, then the system is simple to operate, but positioning accuracy and efficiency are reduced
Solution Approach 1:
The rotating connector introduces dynamic control capability to the previously static hemostasis valve assembly. The ability to rotate the connector dynamically adjusts the guide catheter's orientation and position within the arterial system, enabling precise positioning while maintaining a relatively simple operational interface through manual rotation.
3Adaptability or versatility
If a rotating connector is added to the hemostasis valve, then rotational control is achieved, but the device complexity increases
Solution Approach 1:
The rotating connector is merged with the hemostasis valve body into a single integrated component rather than being a separate attachment. This reduces the number of discrete parts and simplifies the overall structure while maintaining rotational control capability.
Solution Approach 2:
The rotating male luer lock connector is designed to perform multiple functions: providing hemostatic sealing, enabling rotational control, and maintaining fluid flow. This multi-functionality reduces the need for additional specialized components, thereby limiting the increase in device complexity.
