Breathing new life into artificial lungs with polycarbonate

Covestro polycarbonate makes oxygenators safe and durable

Breathing new life into artificial lungs

Membrane oxygenators, also known as artificial lungs, can be used to replace lung function during open heart surgery by oxygenating blood outside the human body.

Polycarbonate makes oxygenators safe and durable
Makrolon® 2458 polycarbonate from Covestro ensures maximum safety for patients using Wego New Life Medical Devices’ membrane oxygenator.


Wego New Life Medical Devices, a well-known medical device manufacturer in China, needed a patient safe polycarbonate that offered biocompability and durability for its membrane oxygenator.


The material selected for the Wego device also had to be transparent, which would allow medical professionals to observe proper functioning of the oxygenating process.


With its glass-like clarity, Makrolon® 2458 polycarbonate from Covestro was the ideal material for the membrane oxygenator. The polycarbonate also exhibits high impact strength and reduces the risk of accidental damage during the course of a surgery. Its biocompability has been tested according to ISO10993, ensuring highest safety for the human body. Covestro has worked closely with Wego since 2008 and has helped achieve the proper balance between benefits and costs for the oxygenators.
