ViVitro Labs AWT-V8 system with Dual Control Technology (DCT)™

The new ViVitro Labs AWT-V8 system with Dual Control Technology (DCT)™ is the first test system designed to automatically detect the onset of valve fatigue failure before any hydrodynamic inspection points, significantly shortening R&D development time.

The Historical Data View of the ViVitro Labs AWT-V8 system leverages its advanced pressure control technology to offer uninterrupted valve health monitoring during AWT studies, and automatically alerts users of potentially undesirable fatigue related events during testing.

The ViVitro Labs AWT-V8 system with DCT™ regulates the differential pressure across valve samples independently of the stroke volume using two separate control mechanisms. By keeping stroke volume constant, the loading conditions at valve closure and opening can be kept constant and stable throughout the duration of the AWT study. Simultaneously, the bypass valve automatically regulates the differential pressure across the valve with minimal impact on the valve kinematics, mitigating the effect of pressure loss due to valve wear.

By controlling stroke volume throughout the duration of the study, the ViVitro Labs AWT-V8 system with DCT™ locks the driving parameter that affects valve motion and the strains experienced by leaflet materials the most, while providing 100% confidence that cycles have achieved ISO 5840 requirements at the end of each AWT study.

The ViVitro Labs software integrated AWT-V8 Valve Comparison Tool simplifies and streamlines the assessment of valve kinematics to increase the reliability of AWT test results. Users can efficiently and reliably determine which AWT test conditions produce the desired valve opening position by comparing any pre-recorded real-time valve kinematics videos side-by-side with a live High-Speed (HS) camera stream from the AWT system.

The ViVitro Labs AWT-V8 system with DCT™ combines the action of a High-Speed Camera with an adjustable intensity annular LED light, a Micrometric Rail Support System, and an integrated Valve Comparison software interface to simplify video capture and provide uttermost consistency in valve kinematics assessment. The side-by-side comparison allows users to quickly and conveniently compare valve motions between samples at any point during a durability study. The Valve Comparison Tool can be used live while controlling the AWT system parameters and viewing test sample health statistics, allowing users to dynamically optimize valve opening conditions.

The ViVitro Labs AWT-V8 Dashboard View increases the efficiency of laboratory resources dedicated to the management of AWT systems by quickly guiding user interventions only when and where they are needed. The Dashboard View of ViVitro Labs AWT-V8 system with DCT™ provides an at-a-glance overview of the status of each test module without navigating through multiple system screens and inefficiently searching for study parameters during AWT studies.

The Dashboard View is a tool designed to optimize laboratory resources and boost efficiency in management of AWT studies.
