Integrated Vascular Access Sheath with Movable Closure Device
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Current medical devices for accessing arteries, such as the radial artery, often require separate devices for gaining access and closing the access point, lacking a comprehensive solution for secure and efficient closure.
Innovation Solution
A vascular access sheath assembly with an elongate sheath and a hub that includes a closure device capable of moving between engaged and disengaged configurations, providing secure access and pressure at the access point, featuring an adjustable mechanism and a viewing window for visualization.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If separate devices are used for gaining access and closing the access point, then device functionality is specialized, but device complexity and procedural time increase
Solution Approach 1:
The patent combines the access sheath and closure device into a single integrated assembly. The closure device is positioned within the sheath and can be deployed from the same access point, eliminating the need for separate access and closure devices. This merging reduces the number of components while maintaining specialized functionality for both access and closure operations.
Solution Approach 2:
The integrated assembly serves multiple functions: the sheath provides access to the vascular system, the closure device seals the access point, and the hub provides structural support and connection points. All these functions are achieved through a single multi-functional device rather than separate specialized devices, reducing procedural complexity.
2Productivity
If a closure device is integrated with the sheath, then procedural efficiency improves, but device complexity increases
Solution Approach 1:
The integrated assembly is divided into distinct functional segments: the sheath portion for access, the hub portion for structural support, and the closure device portion for sealing. These segments are designed to work together as an integrated system while maintaining their individual functional identities, allowing for streamlined deployment without excessive complexity.
Solution Approach 2:
The closure device is designed to be movable relative to the sheath and hub, transitioning between a compressed state within the sheath and an expanded state at the access point. This dynamic capability allows the device to adapt its configuration during the procedure, improving efficiency while managing complexity through controlled movement rather than fixed complex structures.
3Ease of operation
If the closure device is movable between engaged and disengaged configurations, then ease of operation improves, but device complexity increases
Solution Approach 1:
The closure device is pre-positioned within the sheath in a compressed, ready-to-deploy state during the access phase. The hub and sheath are configured in advance to guide and support the closure device's movement. This preliminary positioning and pre-configured support structure enable easy operation during closure without requiring complex real-time adjustment mechanisms.

AI summary
An access sheath assembly can include an elongate sheath for accessing an interior of an artery or vein through an access point on a patient's limb and a hub that is coupled to the elongate sheath and that includes an access port configured to provide access to an interior of the elongate sheath. The assembly includes a closure device configured to fit about the patient's limb and capable of being coupled with the hub, the closure device movable between an engaged configuration in which the closure device is coupled with the hub and thus is positioned to secure the hub relative to the patient's limb and a disengaged configuration in which the closure device is apart from the hub and extends about the patient's limb at the access point in order to provide pressure to the access point.
