Mikro-Cath™ Diagnostic Pressure Catheter

Precision Diagnostics for Cardiac Catheterizations

The Mikro-Cath™pressure catheter delivers true hemodynamic data for deeper insight into cardiovascular function. Clear, accurate signals from the solid-state pressure sensor catheter support in-depth assessments in real-time.

Mikro-Cath™ Diagnostic Pressure Catheter

Ease of Calibration

Simplify your workflow

Mikro-Cath calibration is three simple steps, taking only seconds to complete.

Clean, Accurate Signal

Eliminate the guesswork

The Mikro-Cath signal is unaffected by patient movement or procedural artifacts.

True Hemodynamics

Understand the patient

The Mikro-Cath allows clinicians to make decisions from exact data in real time.

Guide your diagnosis

Mikro-Cath data from the source provides reliable signals for advanced clinical applications, including exercise studies, drug therapy evaluation, heart failure cases and LVAD evaluation. Consider the Mikro-Cath to help guide diagnostic decisions when precise pressure measurements count.

With an appropriately sized guide catheter or introducer, the Mikro-Cath can be easily integrated into any cath lab’s hemodynamic system via standard interface cables, offering an immediate upgrade to the fluid-filled catheter.

In todays environment of rapidly changing technology, why leave hemodynamics behind?

The Mikro-Cath pressure catheter is approved for use in the United States, Europe, and Japan for cardiovascular measurements and is approved for use in the United States and Europe for intra-compartmental and airway pressure measurements. 

Millar CE Mark for Mikro-Cath

Clinicians can obtain more comprehensive and accurate measurements for:

  • Left Ventricular Pressures (LVP)
  • Right Ventricular Pressures (RVP)
  • Mean Arterial Pressures (MAP)
  • Valve Gradients
  • Radial Artery Pressures
  • Peripheral Lesion Pressure Gradients

When compared to fluid-filled catheters, the Mikro-Cath pressure catheter provides real-time, accurate blood pressure data. The Mikro-Tip® sensor measures blood pressure at the source, providing a true representation of the blood pressure waveform, and eliminates many of the common shortfalls of fluid-filled catheters, including signal variances from patient height or position changes.

Indications for Use Statement:

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.
