The ViVitro SuperPump is a digitally controlled hydraulic piston pump that creates physiological cardiac flows. Unsurpassed in reliability, functionality, and versatility, the AR Series digital technology provides maximum control with precision accuracy. The SuperPump works with ViVitro or independently produced accessories to create reliable cardiac flows for any type of cardiovascular device.
The ViVitro SuperPump is used in numerous studies throughout the world. Visit our Citation Database for the current list of applications and articles.
The SuperPump provides maximum operator control with precision accuracy. The pump can be controlled by preconfigured waveforms or by customizable ViViTest software input.
The SuperPump AR is pre-loaded with up to 5 waveforms stored on the controller which enables the pump to be used as a standalone device. Custom waveforms may also be stored on the controller for standalone use.
The ViVitro SuperPump AR Series can be driven by external waveform sources giving flexibility for waveform input. Function generators, personal computers with I/O functionality, custom hardware, microcontroller development boards, and even smartphones can directly control the flow output of the pump. SuperPump feedback can be captured using an oscilloscope or other acquisition device to monitor waveform accuracy. A major advantage of the ViVitro Labs SuperPump AR is its ability to accurately follow user-defined waveforms. The system can provide accurate flows for a wide variety of applications.

Optional - ViVitro ViVigen software enables users to create and upload custom waveforms to the SuperPump.
Sinusoidal or linear waveforms can be modified with the ViVigen interface. Complex waveforms can be created numerically in a spreadsheet for more precision. Waveforms are sent via USB interface from the computer directly to the controller. ViVigen software is intended for third party testing systems, and use with wide ranges of waveforms.
ViVitro ViVitest software is the most advanced solution for the ViVitro SuperPump AR Series system.
It includes all of the waveform generation and review capabilities of ViVigen software, but drives the controller directly during testing. There is no limit to the number of waveforms that can be stored in ViVitest. Users can quickly change between large numbers of waveforms. ViVitest also offers advanced waveform control features such as custom wavetrains with up to 10 unique waveforms and custom cubic spline interpolated waveform generation with up to 20 segments.
The ViViTest control system inputs a waveform to the SuperPump while the data acquisition system captures and analyzes physiological pressures and valve flow rates.
The ViVitro Pump Head can be used with the ViVitro SuperPump to create a circulatory, pulsatile flow loop. The Pump Head accommodates ventricular pressure monitoring using Luer fittings. It may be mounted directly to the SuperPump or can be used in conjunction with the ViVitro Viscoelastic Impedance Adaptor to attenuate pressure traces.
