The Mikro-Cath™ pressure catheter delivers high-fidelity data for analysis of intra-compartmental pressures. Simple, accurate signals from the solid-state pressure sensor catheter provide continuous, real-time assessments to support the diagnosis of acute compartment syndrome or evaluation of chronic exertional compartment syndrome.
Mikro-Cath high-fidelity pressure measurements provide orthopedic surgeons with reliable pressure signals to support and simplify the diagnosis of compartment syndrome for trauma patients. The Mikro-Cath pressure catheter also supports orthopedic research involving 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. Consider the Mikro-Cath for early detection of compartment syndrome to avoid irreversible damage or to prevent misdiagnosis.

The compartment pressure application is approved for use in the United States. Pending CE Approval.
Intra-compartmental pressure measurements support compartment syndrome diagnosis through direct and reliable pressure readings in comparison to fluid-filled pressure measurements or the five “P’s” assessment – pain, paralysis, paresthesia, pallor, and pulselessness.
Compartment syndrome occurs when pressures within the muscles rise to levels above 30 mmHg and are sustained between 40 to 80 mmHg. The pressure is caused by muscle swelling or bleeding that is constricted by the fascia. The swelling disrupts blood flow to the muscle and nerve cells, decreasing oxygen and nutrients. This condition becomes very painful and can lead to tissue damage within the extremity affected. To avoid permanent damage in acute compartment syndrome, the patient must be treated with a fasciotomy within the first 4 hours¹.

Can you confidently diagnosis compartment syndrome with fluid-filled pressure measurement methods? Consider these differences between solid-state and fluid-filled pressure sensor technologies when measuring intra-compartmental pressures.

The Mikro-Cath Pressure Catheter is a single‐use catheter intended to be used for medical research and diagnostic purposes. The catheter is indicated to measure cardiovascular, intra-compartmental, and airway pressures in the human body. The catheter is used as a minimally invasive device under short-term limited body contact (<24 hours).
The typical cardiovascular application will be through the femoral artery with the use of an additional guiding catheter.
Mikro-Cath Pressure Catheter may be introduced into the targeted muscle compartment through an introducer. The Mikro-Cath may be introduced into the respiratory system through an existing orifice or through an incision.
Additional contraindications, precautions and warnings are referenced in the Instructions for Use available under the Knowledge Center acute catheter manuals.
