Interstitial Fluid Pressure (IFP)

Measuring and Recording Interstitial Fluid Pressure

Elevated interstitial fluid pressure (IFP) in human and rodent solid tumors has been recognized as an indicator of reduced therapy response and decreased-free survival rates. Millar catheters provided a simple, accurate method for recording tumor interstitial fluid pressures in a variety of models. As validated by Ugur Ozerdem and Alan Hargens in their publication "A simple method for measuring interstitial fluid pressure in cancer tissues,"1 IFP measurements made by Millar catheters are “simple and…equal to those provided by the well-established, wick-in-needle technique."

To date, Millar's SPR-1000, SPR-320 and SPR-524 pressure catheters have all been used to deliver high quality tumor IFP measurements.

If you are currently performing these measurements using traditional fluid filled systems, contact Millar to learn how Mikro-Tip pressure catheters can provide a simpler alternative to streamline your research protocols.
