Rat Pressure Catheters

The Mikro-Tip® rat pressure catheter is reusable - non-sterile and provides optimal data for monitoring high-fidelity cardiovascular pressures at the source. These pressure catheter models are the state-of-the-art solutions for left ventricular, right ventricular and systemic blood pressure measurements in rats.

The high-frequency response and robust design of these high-fidelity rat pressure catheters enhance your ability to collect the highest quality data, including the most accurate dP/dt values, streamlining your path to publication.

Available Models

Rat Pressure Catheters

SPR-407

Along with the SPR-320, the SPR-407 is one of Millar’s most popular catheters for performing hemodynamic pressure studies in the rat model. With a Nylon catheter body of 1.5F and a 2F pressure sensor, this model offers increased flexibility for users who prefer a less stiff catheter option during surgical placement. The SPR-407 provides a catheter length of 140 cm, which also allows for in vitro use in benchtop applications.

For an entry level hemodynamics system, use the SPR-407 rat pressure catheter with the PCU-2000 pressure control unit, PowerLab 35 Series data acquisition system with LabChart Pro and the Blood Pressure analysis module. Or for the most complete cardiovascular analysis solution for your lab, combine the SPR-407 with the MPVS Ultra® Single Segment Pressure-Volume Loop system and SPR-838 rat pressure-volume catheter.

SPR-320

The SPR-320 Mikro-Tip® pressure catheter is one of Millar's most popular catheters for performing hemodynamic pressure studies in the rat model. With a 2F NiTi wire reinforced, polyurethane catheter body and side-mounted 2F pressure sensor, the SPR-320 model offers increased stiffness for users who prefer a stiffer catheter option during surgical placement. Many users feel this provides optimal delivery across the aortic valve.

For an entry level hemodynamics system, use the SPR-320 rat pressure catheter with the PCU-2000 pressure control unit, PowerLab 35 Series data acquisition system with LabChart Pro and the Blood Pressure analysis module. Or for the most complete cardiovascular analysis solution for your lab, combine the SPR-320 with the MPVS Ultra® Single Segment Pressure-Volume Loop system and SPR-838 rat pressure-volume catheter.

SPR-721

The SPR-721 is a dual pressure catheter that is most commonly deployed in the rat model for pulse wave velocity or aortic stiffness studies. The catheter provides a simultaneous measure of pressure at two locations via a single catheterization. Built to the highest quality standards, the catheter combines two proven Mikro-Tip® pressure sensors for the most accurate pressure measurement.

The first sensor is located at the distal tip of the catheter with the second 5 cm proximal. The catheter has a total working length of 135 cm which also allows it to be deployed in large animal models via an appropriately sized introducer or guide catheter. The catheter is 2F from the first sensor to the second and then increases to 2.5F along the rest of the catheter body.

SPR-940

The SPR-940 is a dual pressure catheter that is most commonly deployed in the rat model to measure valve gradient pressures or for pulse wave velocity via the descending aorta. The catheter provides a simultaneous measure of pressure at two locations via a single catheterization. Built to the highest quality standards, the catheter combines two proven Mikro-Tip® pressure sensors for the most accurate pressure measurement.

The first sensor is located at the distal tip of the catheter with the second 2.5 cm proximal. The catheter has a total working length of 135 cm which also allows it to be deployed in large animal models via an appropriately sized introducer or guide catheter. The catheter is 2F from the first sensor to the second and then increases to 2.5F along the rest of the catheter body.

SPR-513

The SPR-513 Mikro-Tip® rat pressure catheter incorporates a curved tip into the popular SPR-407 design for increased access to the rat right ventricle. The SPR-513 is the preferred solution for right ventricular blood pressure measurements in rats and is an excellent addition to any laboratory’s Millar catheter supply. The high frequency response and minimal catheter diameter enhance your ability to collect the highest quality data possible, including the most accurate RV dP/dt values, streamlining your path to publication.

With a Nylon catheter body of 1.5F and a 2F pressure sensor, this model provides increased flexibility for users who prefer a less stiff catheter option during surgical placement.

The SPR-513 complements a standard entry level hemodynamics rat system consisting of the SPR-407 or SPR-320 rat pressure catheter, PCU-2000 pressure control unit, PowerLab 35 Series data acquisition system with LabChart Pro and the Blood Pressure analysis module. Or for the most complete cardiovascular analysis solution for your lab, combine the SPR-513 with the MPVS Ultra® Single Segment Pressure-Volume Loop system and SPR-838 rat pressure-volume catheter.
