For years, the medical device industry has relied on expanded polytetrafluorethylene (ePTFE) to create vascular stent coverings and grafts. Now, our customers have the opportunity to use a superior alternative with outstanding biocompatibility and biostability that meets the growing regulatory need for a PFAS-free solution. Called Ulteeva Purity™ membrane, this sustainable UHMWPE solution enables us to help you create tomorrow’s solutions today.
30+ years of experience working with the world’s leading medical device and pharmaceutical companies.
20+ years of clinical use for our Ulteeva Purity™ polyethylenes.
100+ years’ experience within our polyethylene innovation team.
With a high strength-versus-volume ratio and consistent properties in all directions, Ulteeva Purity™ membrane is ideal for long-term implantation – and miniaturization. This is an extremely thin (16 μm) and breathable material with a microporous structure that’s ideal for device designers striving to improve patency rates in stent coverings and beyond.
Ulteeva Purity™ membrane also gives you superior dimensional stability in high-motion implantable devices due its high wear and creep resistance; and all with a silky-smooth surface for a low co-efficient of friction. Complementing this, we bring you added peace of mind through:

Ulteeva Purity™ membrane is a superior and sustainable alternative to ePTFE for stent coverings and implantable medical devices and is ideal for use in:
You can also use Ulteeva Purity™ membrane in the design of:
“Based on outcomes from angiography, radiography and histology, both test devices and control devices in all four sheep were widely patent (open) at 90 days. “The results of the study were very encouraging and our expectations for further development and uses of the Ulteeva Purity™ membrane in this arena are high.”
To demonstrate the effectiveness of Ulteeva Purity™ membrane, a team of researchers conducted preclinical studies where a prototype covered stent using our material was compared to a stent featuring ePTFE.
The results showed a favorable similar/noninferior comparison; with the grafts made from Ulteeva Purity™ membrane remaining widely patent (open). As a result - and just like Dr. Virmani says - we have high hopes for this unique polyethylene membrane in this application.
We create sustainable healthcare solutions that deliver tangible and valuable sustainability benefits to our partners – with no compromises on safety or performance.
Looking for more information on how our UHMWPE membrane can help you tackle unmet needs?
We understand that medical product development can be a long, winding - and occasionally bumpy road. Rest assured that at DSM Biomedical, we have the proven experience, capabilities, and knowledge to support you every step of the way.
It starts with using a form-fit-function approach based on a comprehensive understanding of how the human body reacts to biomaterials following implantation. This in turn enables us to design materials that are compatible with the body’s physiology and help you develop finished products that can sustain, restore, and repair – all supported by applicable regulatory requirements.
