The World's Smallest Sensor Tip Pressure-Volume Catheter: PVR-1045

With a catheter tip size of 1F (1/3mm), the PVR-1045 is the newest addition to Millar's market-leading line of ultra-miniature catheters for use in small animal research. The smaller diameter gives researchers a powerful new tool in the characterization of cardiovascular function by allowing access to smaller animals than ever before possible.

Millar’s Mikro-Tip® ultra-miniature P-V catheters have revolutionized the possibilities for cardiovascular research in small animals. These ultra-miniature catheters are capable of measuring both left ventricular pressure and volume simultaneously from the intact, beating hearts of mice and rats. They may be used in either closed-chest or open-chest surgical procedures, as well as in isolated working heart studies.

P-V Catheter Features

  • Ultra-miniature 1F-2F (0.33-0.67 mm outer diameter) pressure sensors
  • Four electrodes (spaced for either mice or rats)
  • Pressure and volume measurement from a single instrument
  • Flexible, durable, small-diameter catheter material
  • High frequency response
  • Pressure measurement at the source
  • No motion artifact or damping of pressure signal
  • For use with Millar Pressure Volume Systems, MPVS 300/400 and MPVS Ultra
