The SPR-864 dual pressure mouse pressure-volume catheter provides a simultaneous measure of aortic pressure and left ventricular pressure and volume in mice 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 7 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 1.4F and 0.8F along the catheter body, this model offers increased measurement capability in hemodynamic studies utilizing mice. Like the SPR-839 pressure-volume catheter, the SPR-864 provides a 3.5 cm usable catheter length and a 4.5 mm electrode spacing for optimized ventricular volume measurement in standard-sized mice.
For complete hemodynamic analysis, use the SPR-864 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.
