Millar Miniature Pressure-Volume (PV) Catheters for Animals

Overview

Millar ultra-miniature pressure-volume (PV) catheters have revolutionized cardiovascular research as their small size means that they can be inserted directly into the heart with virtually no effect on the normal functioning of the heart. These small animal PV catheters are suitable for rabbits/cats. Having a single small animal catheter with the pressure sensor and electrodes allows for simultaneous measurement of both ventricular pressure and volume from a continuously beating, intact heart.

These catheters require the PV Cable for connection to the MPVS Ultra Pressure-Volume Unit (small or large animals) and can be used with the MPVS Ultra Foundation Systems.

A variety of other PV catheters are also available for dog/pig/sheep, mice and rats.

Millar Mikro-Tip Catheters require a certain level of care to ensure accuracy and the anticipated lifespan of your catheters. Tergazyme (Alconox, Inc.) is required for cleaning and ensuring the removal of proteinaceous soils, tissue, blood and body fluids from the catheter. Please refer to Alconox, Inc.’s website to purchase from your local supplier. For a few best practice tips to help get you started with your catheters, see our guide here. Additionally, the purchase of an ESD Adjustable Wrist Strap w/ 10’ Coil Cord (Blue, 4mm Snap) is highly recommended to protect these catheters from electrostatic discharge (ESD) damage during handling.

Calibration:

A Pressure Gauge kit, providing the necessary items to calibrate the pressure transducers, is available.
