Pressure Catheters

Millar Mikro-Tip® solid state catheters with pressure sensor(s) provide high-fidelity cardiovascular pressures (the heart and vascular system) at the source in small animals. These catheters are ideal for intrauterine, intracranial and arterial blood pressure monitoring, amongst other research applications. 

Frequently purchased with Pressure Catheters

Overview

Millar Mikro-Tip® solid state pressure catheters provide an ideal solution for measuring highly accurate pressures. Whether measuring arterial and ventricular blood pressures, spinal pressures, tumor pressures or airway pressures, a high-fidelity sensor from Millar is a necessity for your research. 

  • Single and multiple high-fidelity pressure sensors side mounted at the catheter tip
  • Mice, rats and larger animal models such as pigs and sheep
  • Sizes from 1 F to 5 F
  • Straight and curved tips without pigtail
  • Can be reused for multiple experiments

Catheters require Catheter Interface Cables for connection to any ADInstruments bridge amplifier. Record and analyze blood pressure data quickly and easily using the Blood Pressure Module that is included with LabChart Pro software. A Pressure Gauge kit that provides the necessary items to calibrate the Mikro-Tip® pressure transducer is available. 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.

Non-repairable discount options are available for SPR-671 and SPR-215 Pressure Catheters. Contact us to find out more and if this is the right option for you. More information on Millar repair policies.

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.

Millar have recently simplified their range so that all pressure catheters now work with the Low Profile pressure connector cable, rather than the Viking cable.

Choose from single or dual pressure catheters for large animal models.
