“Maintains constant leaflet closing velocities during the entire AWT cycling period and reduces costly false negative results generated by heart valve prothesis fatigue test systems without Dual Control Technology.”
VICTORIA, BC, October 23, 2023 /PRNewswire/ — ViVitro Labs announces a new generation Accelerated Wear Testing (AWT) System to efficiently mitigate variable leaflet closing velocity test artifacts associated with first- and second-generation systems. ViVitro will showcase the ViVitro Heart Valve Accelerated Wear Testing System with DCT™ (Dual Control Technology), at TCT 2023 in booth 348 on October 24 – 26, 2023, at the Moscone Center in San Francisco, CA. The revolutionary self-regulating AWT system reduces false negative results generated by most heart valve fatigue testing systems.
Variable leaflet closing velocities of heart valve prosthesis during the AWT cycling period is associated with premature wear and over testing of perfectly sound valve designs. This test artifact can have a detrimental impact on R&D cost and development timelines.
The ViVitro AWT System with DCT™ wowed attendees during a sneak preview at TCT in September 2022, garnering record-breaking demand. Since TCT 2022, the ViVitro AWT System with DCT™ has undergone extensive system performance evaluation in various normal and severe test conditions to pass ViVitro’s verification and validation requirements. ViVitro will be accepting new orders at and after TCT.
Karim Mouneimne, President of ViVitro Labs Inc., explains how Dual Control Technology regulates test conditions and stabilizes leaflet closing velocities during AWT.
“The ViVitro AWT System with Dual Control Technology (DCTTM) is an innovation in fatigue testing of heart valve prosthesis that will help valve developers push the envelope of medical device technology.
The ViVitro AWT System with DCTTM uses two separate position feedback sensors and algorithms to maintain constant leaflet closing velocities across the entire AWT cycling period.
Piston displacement and bypass valve position are controlled independently to meet differential pressure requirements while preserving initial leaflet closing velocities. The combined action of both feedback sensors forms our Dual Control Technology, DCT™”.
ViVitro AWT system performance improvements and enhancements since its TCT 2022 preview include:
- Simplified DCT™ User Interface and Optimization of 5% Rule
- Improved interchangeability of parts
- Increased system physical robustness
- Enhanced filtering systems and immunity on pressure signals inputs
- Advanced motor current monitoring
- Further system noise reduction
- Optimized system thermal management
