Pressure-Volume (PV) Loop Solutions

MPVS Ultra Single Segment

Product Number: 880-0168SS

Millar’s MPVS Ultra Single Segment provides a cost-effective solution for getting started with mouse or rat PV loop studies with an appropriately sized PV catheter. This system includes two pressure amplifiers, a single segment of volume measurement, intracardiac ECG and intuitive software control to support invasive ventricular pressure and volume measurements.

The analog BNC outputs allow the measured primary pressure, volume and internal ECG signals to be recorded directly by an ADInstruments PowerLab and LabChart data acquisition system via BNC-BNC cables. The additional pressure BNC output provides a secondary pressure signal when used with a dual pressure or another pressure catheter.

As your research evolves from rodent studies to larger animal models, your MPVS Ultra Single Segment unit can evolve with you. A simple software upgrade will unlock the MPVS Ultra's full capacity, allowing volume measurement across seven electrode segments with Millar Ventri-Cath multi-segment PV loop catheters.

Pressure-Volume (PV) Loop Catheters

For complete pressure-volume (PV) loop analysis in large and small animal models, Millar’s pressure-volume (PV) loop catheters integrate seamlessly with the MPVS Ultra® pressure-volume loop system. These catheters combine pressure sensors and electrodes for simultaneous high-fidelity pressure and volume measurements, enabling minimally invasive, continuous, intracardiac pressure-volume analysis.

PV Loop Catheters are available in 1 to 6 French catheter tip sizes and single-field or dual-field configurations to accommodate various heart sizes, and are applicable for closed-chest or open-chest surgical procedures and isolated working heart studies.
