What is ECMO?

ECMO is a very complex lifesaving technology that provides circulatory and respiratory support to very sick patients experiencing some kind of circulatory or respiratory failures due to a range of clinical conditions including premature birth, congenital defects, influenza complications (increasingly), COPD, severe trauma from battlefields or serious accidents. It can also be used to keep donor’s organs perfused after death or recondition and preserve them for transplants purposes (a growing concern for transplant doctors).


Elsius’s Portable Cardiopulmonary Assist System


pCAS explanation
Portable Cardiopulmonary Assist System

Next-generation advanced compact circulatory support system providing enhanced efficiency, usability, portability, and blood compatibility
• Comprised of a disposable, integrated pump-oxygenator driven by a touch-screen based controller console
• Current system may be used as a “partial support” adult system or a “full support” pediatric system
• Leverages Ension surface technologies:
– Ension bioactive surface (EBS)
– Ension infection resistant surface (EIRS)

A principal feature of the pCAS system is the Ension Bioactive Surface (EBS)
It’s a proprietary engineered surface developed by Ension specifically for ECMO/ECLS (gas exchange) applications
It’s a covalently bonded, highly gas permeable, heparin-based bioactive surface treatment
EBS is designed to mitigate activation of cellular elements in the blood and development of thrombi

All blood contacting surfaces of the pump-oxygenator unit are treated with the EBS
