Continuous Compartment Pressure Measurements

The Mikro-Cath™ Pressure Catheter uses our proven pressure sensor technology to record precise measurements within compartments of the body, typically in the upper and lower extremities, to monitor for compartment syndrome.  The continuous, real-time data supports the diagnosis of acute compartment syndrome (ACS) or the evaluation of chronic exertional compartment syndrome (CECS).

Chronic Exertional Compartment Syndrome (CECS)

The Mikro-Cath™ pressure catheter supports orthopedic research and sports medicine physicians who monitor chronic exertional compartment syndrome and can be used in exercise studies due to the solid-state pressure sensor's stability. This stability delivers reliable, accurate measurements even during patient movement.

With an appropriately sized introducer, the Mikro-Cath™ can be easily inserted into the targeted muscle compartment for continuous measurements up to 24 hours.

The Mikro-Cath provides the advantage of continuous pressure monitoring, reliable signals, and ease of use. With the catheter tip at only 3.5F (1.17 mm), the puncture wound is smaller than other catheter options. Patient movement also does not interfere with the signal quality compared to fluid-filled devices.


Benefits of High-Fidelity Data Using the Mikro-Cath™

The Mikro-Cath™ offers improved sensitivity and specificity over existing methods in the diagnosis of anterior compartment CECS by obtaining continuous, high-fidelity data.  Benefits include:

  • Ability to evaluate average pressure trends and assess data in real-time
  • Knowing exact time when pressures cross and sustain threshold levels
  • Reduces stress to the patient to have one catheter introduced compared to multiple needle insertions every 1 to 2 hours for up to 24 hours as required by traditional single-point monitoring systems
  • Fewer pressure measurements/procedures (time) needed from a physician
  • Less risk of false measurements with solid-state sensor technology (air bubbles/proper calibration/angle/patient movement)
  • More cost-effective if monitoring for extended periods of time


According to a 2004 study, compartment syndrome diagnosis is one of the most common sources of litigation against orthopedic surgeons. The average cost of a settlement for undiagnosed compartment syndrome has been cited at $426,000.30. There is value in bringing higher confidence back into the equation.
