EKOS catheter

EKOS™ Endovascular System

Proven history and technology

The first choice in the interventional treatment of pulmonary embolism (PE)

The new standard of care for pulmonary embolism treatment

EKOS was the first interventional device cleared for treating pulmonary embolism. Today, it’s trusted by more clinicians than any other PE device.


  • 2005 First

  • 2008 EKOS receives peripheral vascular indication
  • 2008 First DVT data published
  • 2021 DVT indication
  • 2014  EKOS receives PE indication
  • 2021  EKOS+ clearance    
  • 2022  EKOS+ first patient case    

One 15-minute procedure can deliver dramatic results

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.

How EKOS works

EKOS ultrasound technology unwinds and thins fibrin strands to expose more drug receptor sites; acoustic streaming drives the drug deeper into the clot.

Superior clot dissolution

Clinically proven to be safe and reliable with long-term outcomes

  • Minimally invasive, 15-minute procedure that is easy to perform
  • Low lytic dosing: as low as 8 mg tPA used1
  • Prescribed protocol that allows for predictable procedural workflow and proven patient outcomes

Powered by Control Unit 4.0

The EKOS CU4.0 includes an interactive color touchscreen, a built-in battery and separate ports for managing two EKOS devices simultaneously, simplifying bilateral treatment of PE.
