EKOS™ Endovascular System

A first-line pulmonary embolism intervention. Proven to yield safe and effective results, EKOS is low risk and reliable. Because of EKOS’ small size, it allows further reach into smaller distal pulmonary vessels. The EKOS+ catheter builds on the legacy of EKOS, and provides more ultrasound power to resolve clot burden more quickly and completely.

EKOS features & benefits 

EKOS is a safe, repeatable and reliable treatment that dissolves thrombus quickly with low lytic, low blood loss and low trauma – resulting in proven long-term outcomes. EKOS leverages the power of targeted ultrasonic waves to thin and separate fibrin strands and accelerates lytic dispersion deeper into the clot. The addition of the new EKOS+ catheter offers the same procedure & clinical workflow, with 50% more ultrasound power.1

Ultrasonic core technology

  • Minimally invasive, 15-minute EKOS procedure that is quick to perform
  • Lytic agent: as low as 8 mg tPA used2
  • Ultrasonic waves accelerate clot dissolution by unwinding and thinning fibrin strands to expose more drug receptor sites; acoustic streaming drives the drug deeper into the clot for safe dissolution
