Covestro medical-grade Makrolon® polycarbonate utilized for breakthrough wound healing device

Potential to transform wound healing


Vaporox’s Vaporous Hyperoxia Therapy (VHT®) technology is clinically validated for healing skin wounds. A combination of Covestro resin and technical support helps bring next-generation wound care medical device to market.


Chronic wounds afflict millions of people. If not treated adequately, they can lead to severe complications, including amputation of limbs. Denver-based Vaporox developed a medical device for healing chronic wounds that do not respond to conventional wound treatment. The vaporizer component of the medical device primarily utilizes Makrolon® 2458 polycarbonate from Covestro.

The VHT-200 (Vaporous Hyperoxia Therapy™) system, which received U.S. Food and Drug Administration (FDA) clearance, features a unique combination of elements that accelerate healing—ultrasonic vapor and concentrated oxygen. According to Vaporox, the patented delivery system for these elements promotes revascularization and tissue growth. The treatment is intended for administration in clinics and physicians’ offices.

“Vaporox is committed to a world where all wounds heal,” said Chase Huskey, marketing manager, Vaporox. “Today, wound care is one of the most under-served markets in the medical industry, but this development is truly life-changing for patients and a huge step forward for this market.”

Covestro was involved throughout the device’s development, supplying prototype quantities of its material, and documentation required by the FDA.

Makrolon® 2458 polycarbonate is a low-viscosity, injection-molding medical grade that features easy release from the mold. It is suitable for Ethylene Oxide (EtO) and steam sterilization and is biocompatible according to many ISO 10993-1 test requirements. It is available in transparent and opaque options.

“For decades, the healthcare market has relied on our proven portfolio of medical grade Makrolon® polycarbonates, complemented by customized technical expertise,” said Mark Nichols, healthcare key account manager, Covestro LLC. “Our work with Vaporox demonstrates the value of collaboration as our customers develop and bring truly innovative, game-changing technology to market.

Attendees at MD&M West, February 6-8 in Anaheim, California, can visit the Covestro booth (#2221) to learn how the company’s materials push boundaries in healthcare applications.
