8 REASONS TO ADOPT THE VIVITRO LABS AWT-V8 WITH DUAL CONTROL TECHNOLOGY (DCT)TM FOR HEART VALVE PROSTHESIS DURABILITY TESTING

REDUCE YOUR HEART VALVE PROSTHESIS DEVELOPMENT COST –

ONLY USE AN AWT SYSTEM WITH ADVANCED PRESSURE CONTROL TECHNOLOGY

The ViVitro Labs AWT-V8 system with Dual Control Technology (DCT)™ was developed to address the limitations of older 1st and 2nd generation test systems on the market and provides optimum performance and cost-benefit to customers engaged in the development of cardiac implants.

Decrease your development cost – Don’t wait for hydrodynamic inspection to discover valve fatigue failure.

The ViVitro Labs AWT-V8 system with DCT™ is the first test system to detect the onset of valve fatigue failure before any inspection points and shorten R&D development time. The AWT-V8 system actively monitors the rate of change of its bypass valve or any abrupt and sudden changes in bypass valve adjustment, and automatically alerts users of potentially undesirable fatigue related events.  The ViVitro AWT-V8 system with DCT™ leverages its advanced pressure control technology to offer users an uninterrupted historical view on specific test parameters to assess the health of valve samples during AWT studies.

The ViVitro Labs AWT-V8 system integrated Historical Data View allows users to:

  • Detect subtle changes in valve behavior by continuously monitoring the patented bypass valve of the system
  • Monitor the progression of the critical study parameters over time to determine the exact time of potential adverse events
  • Streamline viewing and analysis of large data sets in support of root cause activities
  • Monitor system health during studies by providing data for preventive maintenance interventions

Decrease your development cost – Don’t overload your valve samples and prematurely fail your AWT study

The advanced pressure control technology of the ViVitro Labs AWT-V8 system with DCTTM provides a unique opportunity to device manufacturers to mitigate the impact of costly test artifacts generated by older generation AWT systems.   Unlike older generation AWT systems on the market, the Dual Control Technology (DCTTM) of the ViVitro Labs AWT-V8 system protects valve samples from being subjected to variable loading conditions at valve closure and opening and simultaneously maintains repeatable valve kinematics regardless of wear on the leaflets.

The advanced differential pressure technology of the ViVitro Labs AWT-V8 system regulates the differential pressure across the valve sample independently of the stroke volume using two separate control mechanisms. By keeping the 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, to mitigate the effect of the pressure variation due to valve wear, the bypass valve automatically regulates the differential pressure across the valve with minimal impact on leaflets kinematics.   By controlling stroke volume throughout the duration of the study, the ViVitro Labs AWT-V8 system with DCTTM locks the driving parameter that affects valve motion and strains experienced by leaflet materials the most. The independent control of the bypass valve optimizes the differential pressure across the test sample with minimal impact on valve motion while optimizing passing cycles. At the end of the AWT study, customers have 100% confidence that cycles have achieved ISO 5840 requirements.

Optimize your R&D program timelines by reliably estimating the end of your AWT studies

The ViVitro Labs AWT-V8 system advanced pressure control technology is designed to optimize passing cycles (per ISO 5840 requirements) to improve predictability of AWT study completion while reliably meeting differential pressure conditions during the entire duration of the study.  With its proprietary Dual Control Technology (DCT)™, the ViVitro Labs AWT-V8 System uses two separate position feedback sensors and algorithms to regulate and maintain the differential pressure conditions.  The ViVitro Labs AWT-V8 system Dual Control Technology controls the displacement of the AWT-V8 system shaker/piston to generate a constant stroke volume and independently regulates the differential pressure across valve samples with its bypass valve while optimizing passing cycles.  The combined action of the two control mechanisms of AWT-V8 system produces a reliable cycle count for passing cycles through out the study and instantly informs users on the number of cycles meeting ISO 5840 requirements.

Optimize your R&D program timelines by minimizing AWT downtime during hydrodynamic inspection.

The ViVitro Labs AWT-V8 system with DCT™ is designed to minimize down time during hydrodynamic inspection periods. The AWT-V8 system has 6 true standalone test modules that can act as 6 single independent and autonomous instruments to reduce test samples down time during hydrodynamic inspection. With a true standalone architecture, users can inspect test samples individually without disrupting other test modules.  While hydrodynamic and visual inspection is conducted on one single sample coming out of the AWT-V8 system, other test samples continue to accumulate cycles regardless of the length of the inspection.

In addition, each test module is designed to give quick access to test samples with no loss or contamination of test fluid or spillage in the surrounding environment and no interference with other test modules.

Optimize your early-stage R&D budget by using an AWT system with True Standalone architecture

Thus, the true standalone architecture of the ViVitro AWT-V8 system with DCT™ with plug and play test modules can be adapted to fit R&D budget requirements by adding capacity as needed.

The ViVitro Labs AWT-V8 system with DCT™ is designed to provide maximum modularity and flexibility during early-stage R&D phases when design iterations are frequent.  The AWT-V8 system with 6 true standalone plug and play test modules act as 6 single independent and autonomous instruments which allows engineers and technicians to run test samples with different sizes and configurations, on different protocols and under different test conditions. The software user interface with its tabular configuration allows users to enter chamber specific test sample identification and setup independent test parameters.  As the R&D program reaches maturity, the 6 independent test modules can be individually programmed to run under the same protocol and test conditions.

Optimize your R&D program timelines by using a True Standalone architecture to minimize down time during AWT maintenance

The ViVitro Labs AWT-V8 system with DCT™ is designed to minimize down time during maintenance. Our AWT-V8 system has 6 standalone plug and play test modules which act as 6 single independent and autonomous instruments to allow engineers and technicians to intervene on a single test module without disrupting or compromising test samples running on any adjacent modules. Test modules can be changed at will and easily replaced by simply plugging in backup test modules.  The original test sample can be transferred back to a new or backup module without loss of data.  The system will automatically recognize the new unit and update the data set of the test sample under evaluation to only identify the replacement module.

Streamline AWT studies while increasing test results reliability with the ViVitro Labs AWT-V8 Valve Comparison Tool

The ViVitro Labs software integrated Valve Comparison Tool increases AWT test results reliability by simplifying and streamlining valve kinematics assessment.  Users can efficiently and reliably determine AWT test conditions leading to maximum valve opening position by comparing side-by-side any pre-recorded valve kinematics video segment to a live High-Speed (HS) camera stream. The live side-by-side video comparison can be conducted while controlling the AWT system parameters and viewing test sample health statistics, allowing users to dynamically optimize valve opening conditions. The combined action of the ViVitro Labs AWT-V8 High Speed Camera Kit with the Valve Comparison Tool software interface, the Micrometric Rail Support System and the adjustable intensity annular LED light increases study reliability and provides uttermost consistency in valve kinematics assessment between inspection cycles.
