Zeus Bioweb™ is a technology produced through electrospinning PTFE into polymeric fibers with extremely small diameters ranging from nano- to microscale. Collectively, these electrospun filaments form materials with a broad range of fiber and fabric properties. An example of this is increased dimensional stability through a broad range of temperatures when compared to traditional ePTFE. As a biocompatible material, Bioweb™ is particularly suited to a host of medical applications as well as other general industrial uses.

Electrospinning creates products that possess high surface-to-weight and volume ratios while still maintaining excellent mechanical properties. As a non-woven composite, Bioweb™ has a microporous nature that is similar to expanded PTFE (ePTFE) but achieves this without the nodes and fibrils associated with ePTFE. As a result, Bioweb™ can often attain thinner profiles than ePTFE making Bioweb™ highly suited to small vasculatures. The low chemical reactivity of Bioweb™ also means that this material will not degrade metal stent frameworks. PTFE has a long history of medical use and is easily integrated into implantable applications.

At Zeus, we have the ability to create encapsulation technology, electrospin membrane / sheet, and develop coatings for 3-D substrates in a variety of shapes and sizes. Membranes and coverings can be further modified to increase performance specific to the application.

As a leader in the development and production of medical device components, Zeus provides critical intellectual and physical resources essential to bringing new technologies to the market. In addition to providing Bioweb™ as a stent covering, Bioweb™ is available license-free via a technology transfer agreement for you to cover your own stents or other implantable devices. Our Research division focuses on quality prototype development, assembly solutions, review, and analysis. We assist at every stage of the technology transfer and assure the success of your next project.


    Implantable Structures In The Body – The microporous surface of Bioweb™ is ideal for uses within the body whether for coating substrates, stent coverings, or membranes.

    Scaffolding – Bioweb’s™ high surface-to-weight ratio makes this material particularly adapted for tissue scaffolding because of its extra-large interface with the surrounding biological environment.

    Stent Encapsulation Capability – As a stent covering, Bioweb™ composites allow for safe and non-inflammatory implantation of these devices to affect successful treatments in diverse endovascular scenarios.


    Biocompatibility – Bioweb™ is non-toxic and can safely exist in the body.

    Continuous Membrane or Sheet – This non-woven product is particularly amenable to being formed into sheets or membrane allowing a variety of additional uses.

    Excellent Material Properties – Because Bioweb™ utilizes PTFE, the electrospun PTFE retains all of the highly beneficial properties this fluoropolymer is known for including biocompatibility and ETO and autoclave sterilization compatibility.

    Low Temperature Encapsulation – Bioweb™ stent encapsulations can be performed at comparatively low temperatures preventing damage to the stent framework.

    Low Chemical Reactivity – Bioweb’s™ minimal chemical reactivity means that this material will not degrade the metal stent framework.

    High Surface-To-Weight Ratio – Bioweb’s™ high surface-to-weight ratio and the tight pore sizes of the electrospun PTFE make this material superior to other fibers for tissue in-growth. Additionally, the high surface-to-weight ratio creates a very large interface between Bioweb™ and its surrounding environment compared to conventional or similar biocompatible products. This increased interface allows greater permeation of chemical signals and other molecules as an implantable or wound covering device.

    Microporous – The extremely small fiber diameter resulting from our electrospinning process produces a material that also possesses extremely small (1 – 4 μm typical) pore sizes creating tiny frameworks suited for implantation or as wound coverings.
