The SPR-901 dual pressure rat pressure-volume catheter provides a simultaneous measure of aortic pressure and left ventricular pressure and volume in rats via a single catheter placed via the carotid artery. Built to the highest quality standards, the catheter combines two proven Mikro-Tip® pressure sensors with four electrodes to collect real-time pressure-volume data.
The left ventricular pressure sensor is located between the four volume measurement electrodes at the tip of the catheter while the second aortic pressure sensor is located 12 mm from the LV sensor. This catheter is ideal for adding a measurement of total peripheral resistance to your PV loop studies
With a pressure sensor diameter of 2F and 1.1F along the catheter body, this model offers increased measurement capability in hemodynamic studies utilizing rats 350 g and larger. Like the SPR-838 pressure-volume catheter, the SPR-901 provides a 12.5 cm usable catheter length and a 9 mm electrode spacing for optimized ventricular volume measurement in standard-sized rats.
For complete hemodynamic analysis, use the SPR-901 mouse pressure-volume catheter with the MPVS Ultra® or MPVS Ultra® Single Segment system, PowerLab 35 Series data acquisition system with LabChart Pro and the PV Loop analysis module.
