Mikro-Cath™ Diagnostic Pressure Catheter

Precision Diagnostics for Cardiac Catheterizations

The Mikro-Cath™ diagnostic 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 – all from routine catheterizations.

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 traditional fluid-filled catheter.

In todays environment of rapidly changing technology, why leave the cath lab behind?

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 traditional fluid-filled catheters, the Mikro-Cath pressure catheter provides more complete and 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 is a single-use cardiovascular catheter intended to be used for medical research and diagnostic purposes. The catheter is used to measure hemodynamic cardiac pressures in the human body to allow physicians to better understand cardiac health. The catheter should be used as a minimally invasive device under short term limited body contact for less than 24 hours. The typical application will be through the femoral artery with the use of an additional guiding catheter.

Additional contraindications, precautions and warnings are referenced in the Instructions for Use available under the Knowledge Center acute catheter manuals.
