VentriFlo®

Apex™ Counterpulsed VA-ECMO

VentriFlo Apex is an ECG-synchronized, counterpulsed VA-ECMO system. Built-in LV unloading, preserved pulsatility, and a path to facilitates weaning — all from a single bedside cannulation.

  • THE PROBLEM
  • CLINICAL NEED

Cardiogenic shock
outcomes haven’t moved.

Despite three generations of temporary mechanical circulatory support (tMCS), mortality stays stubbornly high.

SCAI STAGE C

SCAI STAGE D

30-day mortality in cardiogenic shock remains 40–63%. Hospitalizations have roughly tripled since 2004 and continue to climb, costing U.S. hospitals an estimated $11–14 billion a year.

  • WHY IT MATTERS

Current options leave a gap

Each current option closes some gaps while leaving others open. Apex is designed to close them from a single device.

pVAD

actively unloads the LV and reduces cardiac workload, but requires invasive cross-valve insertion, suppresses microcirculation, and offers no oxygenation — at the highest cost — falling short of a combined, less-invasive solution.

IABP

preserves pulsatility and microcirculation through counterpulsation at low cost, but provides no oxygenation and no meaningful forward flow support, falling short of the hemodynamic support needed in true cardiogenic shock.

VA-ECMO

provides full oxygenation and bedside deployability at moderate cost, but its continuous competitive flow increases LV afterload and reduces microcirculatory perfusion — falling short of the need for simultaneous gas exchange and cardiac unloading.

  • THE SOLUTION
  • TECHNOLOGY

One device, every objective.

ECG-synchronized counterpulsed VA-ECMO — built-in LV unloading,
preserved pulsatility, and facilitates weaning.

Сombining oxygenation and unloading and physiologic flow in one platform

Three parts. One system.

01

Single-use pump, membrane & valves

Single-use volume-displacement pump with a flexible membrane, integrated valves, disposable blood path.

02

Pump driver

Pump driver that powers and controls the pumping mechanism with precise performance.

03

Control console

ECG-gated control console with user-guided operation, customizable stroke volume, flow rate.

  • HEART RECOVERY

Cardiogenic shock needs a path to recovery — the case for giving circulatory support a pulse.

The case for giving temporary circulatory support a pulse begins early in the cardiogenic shock cascade, when heart recovery is the goal. By combining counterpulsation that delivers an added pulse between heartbeats, biventricular oxygenation that supports both ventricles through one circuit, and precise ventricular unloading that removes volume so the heart can rest, this approach is designed to restore circulation while giving the heart and body the best opportunity to recover.

CONTINUOUS FLOW

PHYSIOLOGIC PULSE

Reduced workload

Associated with reduced myocardial workload versus continuous flow.

Works with
the heart

ECG-synchronized counterpulsation augments the heart’s own rhythm rather than overriding it.

Better perfusion

Associated with improved coronary and renal perfusion and healthier microcirculation.
