Organ preservation system brings new life with polycarbonate

Keeping a steady beat

Safely transporting organs can mean the difference between life and death. Yet, the traditional method used to preserve organs during transplantation comes with limitations.

To improve the way organs are preserved during transportation, TransMedics, Inc. developed the Organ Care System (OCS™). This portable system delivers warm, nutrient-rich blood to the organ, allowing it to function outside of the body and enabling organ optimization and assessment.


TransMedics has three OCS™ products – OCS™ Heart, OCS™ Lung and OCS™ Liver, each of which has three primary components: a portable console with a wireless monitor, a disposable perfusion set and nutrient-enriched solutions. The company needed tough and transparent materials for these devices.


The perfusion set’s clear enclosure, which protects the organs, uses Makrolon® 2458 and Makrolon® Rx1452 polycarbonates from Covestro. Additionally, the attached connectors utilize Makrolon® Rx1805 polycarbonate. Beyond supplying the materials, Covestro provided technical support and shared regulatory knowledge to help further the development cycle.
