The TherOx SSO2 System

Contact a Product Expert

The TherOx SSO2 System includes three device components: a console, cartridge, and SSO2 catheter. Together, these components create and deliver SuperSaturated Oxygen (SSO2) Therapy to the patient following an acute heart attack.

TherOx Console
The console is a mobile hardware device that controls Cartridge operation.

DownStream Console 2
DownStream Cartridge

TherOx Cartridge
The cartridge is a disposable component that creates superoxygenated saline using hospital saline and oxygen, and then continuously mixes it to create superoxygenated blood.

SSO2 Catheter
The SSO2 Catheter is a 5F (O.D.) over-the-wire catheter that delivers the superoxygenated blood into the left main coronary ostium using the femoral access site.

DownStream Catheter

TherOx MI

SSO2 provides localized hyperoxemic oxygen for the heart to help it heal after a heart attack. This elevated oxygen concentration enables increased diffusion of oxygen to ischemic tissue. Immediately following successful PCI, SSO2 is delivered via catheter to the myocardial tissue which may be at risk of permanent loss.

Indications For Use: The TherOx DownStream System is indicated for the preparation and delivery of SuperSaturated Oxygen Therapy (SSO2 Therapy) to targeted ischemic regions perfused by the patient’s left anterior descending coronary artery immediately following revascularization by means of percutaneous coronary intervention (PCI) with stenting that has been completed within 6 hours after the onset of anterior acute myocardial infarction (AMI) symptoms caused by a left anterior descending artery infarct lesion.
