Bioweb™

Bioweb™ PTFE/PU composite membranes provide an efficient adhesion platform for stents and scaffolds, enabling low-profile encapsulation over nitinol frames without sutures at a much lower temperature (266 °F / 130 °C) than traditional ePTFE coverings (572 °F / 300 °C). In addition to lower temperature bonding than ePTFE, Bioweb™’s PU layer combined with the PTFE layer provides isotropic mechanical properties, allowing Bioweb™ to encapsulate a wider variety of frames and unique geometries.

As an electrospun product, Bioweb™ possesses excellent isotropic mechanical properties. The electrospinning process produces a composite matrix with microporous qualities similar to that of ePTFE. However, the pores seen in the outer layer of PTFE in Bioweb™ are typically larger (3-5 μm) before sealing, resulting in potentially improved endothelialization when compared to pure ePTFE coverings.

As a global leader in the development and production of advanced medical device components, Zeus provides a wide array of resources, including an extensive network of field application engineers (FAEs), to assist you in bringing your new technologies to the market. Our team will work with you to evaluate your frame structures, confirm our ability to encapsulate them with prototype samples of Bioweb™, and before commercialization, guide you through a fast and easy technology transfer agreement enabling you to cover your own stents or other implantable devices with Bioweb™.
