For better understanding of heart diseases and better treatment development, researchers need to quantify the performance of the heart, more than relying only on blood pressure or ventricular pressure. They need to investigate subtle changes in contractility, elastance, energetics and efficiency.

To achieve this goal, emka TECHNOLOGIES provides Pressure-Volume loop system from Transonic Scisense, to be used with IOX2 acquisition software, for the study of hemodynamics and cardiac function in small and large animals hearts.

The basic system includes the following:

  • Transonic ADVantage Pressure Volume system:
    • ADV500 module equipped with one pressure volume input and one additional pressure input
    • Catheters
  • IOX software
  • usbACQ device to interface with the acquisition computer and provide the following analog outputs : Pressure 1 and 2, Volume, Phase and Magnitude

Catheters are available with a range of volume electrode spacings to fit any ventricle size, from rodent to large animals.

Variable Segment Length (VSL) catheters are also available for even more flexibility in matching ventricle sizes. They have 4 volume electrode options designed to offer flexibility and ensure proper fit.

Rodent Pressure Volume catheters are specifically designed for use with mice and rat sized ventricles.

Pressure Volume Catheters for large animals range in size from 3.5F to 7.0F to span the entire range of heart sizes from rabbits to cows. All 7.0F Catheters are available with an optional lumen to allow drug administration, blood sampling or guide wire insertion.
