The history of the oxygenator, or artificial lung, dates back to 1885, with the first demonstration of a disc oxygenator, on which blood was exposed to the atmosphere on rotating discs by Von Frey and Gruber.

A team of doctors led by Dr . C . Walton Lillehei opened the boy's chest, hooked his circulatory system to a new device called a bubble oxygenator, cut open his heart and closed the hole with a few sutures.

The early artificial lungs used relatively impermeable polyethylene or Teflon homogeneous membranes, and it was not until more highly permeable silicone rubber membranes were introduced in the 1960s ( and as hollow fibres in 1971 ) that the membrane oxygenator became commercially successful.

The first commercial minimized extracorporeal circulation was the CorX System from Cardiovention, a start-up company from the USA . This system included an integrated centrifugal pump polypropylene oxygenator, a complete heparin-coated surface and a low priming volume.
