Heart Valve Prosthesis
Accelerated Wear Testing with

The ViVitro AWT-V8 System is a fully software-controlled instrument with a proprietary user-friendly interface to control and maintain AWT test conditions specified in ISO 5840.

• Fully software-controlled standalone test modules for user-friendly, easy system handling – up to 6 independent standalone modules for advanced study control and monitoring.
• Validated and proprietary software interface
• Independent settings and controls for each standalone test module, including stroke amplitude and bypass valve control for target differential pressure adjustment, test frequency, % of cycle meeting ISO requirements and total number of passing cycles
• Individual test module parameter displays for live data overview: passing cycles count, operating frequency, fluid temperature, peak to peak differential pressure, % of cycles meeting pressure target, total number of passing cycles and more
• Continuous and/or periodic data monitoring and records in compliance with ISO 5840 Accelerated Wear Testing (AWT) and Dynamic Failure Mode (DFM) requirements
• Easy control and settings navigation between test modules

• Live data overview table for each module in one single display
• Integrated pressure calibration wizard
• Live real-time waveform display for inflow pressure, outflow pressure, differential pressure, stroke amplitude
• Study parameters and test sample identification data embedded in test log with calibration values
• Independent close loop control of fluid temperature for each standalone test module with dedicated sensors and heating probes
• Fluid temperature measurement recorded for each test cycle
• Individual standalone test module management including system status: connection, cycling, data logging and error monitoring/logging
• Visual notification of test module error modes for quick system assessment and ease of management of AWT studies
• Ease of use auto complete feature to avoid total number of cycle overshoot and valve overloading at the end of the study
• Ease of use auto pause feature to avoid total number of cycle overshoot at valve inspection point
• Ease of use auto pause feature when system error is detected
• Final test summary file for each standalone test module at the end of its AWT study
• Data file integrity verification tool for regulatory purposes
• AWT software version V8 verified and validated on Window 11 OS with certificate of conformity against ISO 5840:2021

• User friendly and intuitive file naming nomenclature including time and date of file creation, valve ID, trial name, and standalone test module
• Data recording for every test cycle (total number cycles, total passing cycles, peak differential, % of cycle meeting target pressure, fluid temperature, motor temperature, motor % utilization, bypass valve % position)
• Data collected for the entire study and saved over multiple .CSV files
• Data recorded in engineering units
• Convenient file sizes for easy handling: Max 10 mb per file

• Periodically save entire waveform with user predefined output data
• Total 12 parameters: 4 defaults and 8 user selected
• User configurable number of cycles and frequency of capture
• User friendly and intuitive file naming nomenclature including: time and date of file creation, valve ID, trial name, and standalone test module
• Convenient file sizes for easy handling
