ePTFE Stent Covers & ePTFE Covered Medical Devices
Due to its many unique properties, ePTFE is an excellent choice for medical device applications requiring low friction, flexibility, strong and thin membranes, with excellent long term biocompatibility and hemodynamics. The unique properties of ePTFE covered stents, valves and other implantable ePTFE covered medical devices enable the latest technologies in structural heart, peripheral vasculature, neurovascular, orthopedic, pulmonic, bariatric and many other specific medical applications where low profile, high strength, lubricity, and excellent long term implant durability are critical design factors.
At DUKE Empirical, we produce a wide range of ePTFE membrane materials for unique device requirements such as self-expanding and balloon expandable stents and implantable devices. DUKE Empirical will work with you to design and manufacture ePTFE covered stents and medical devices based on your project’s exact specifications. DUKE Empirical extrudes ePTFE tubing and develops material solutions in house for a variety of applications including all fluoropolymer catheters, delivery capsules for implant delivery systems, coil and braid reinforced ePTFE vascular access products, as well as a line of deflectable ePTFE guide catheters and sheaths. DUKE Empirical has developed a unique material technology called FluoroSlix® which combines the low friction of ptfe with the flexibility of rubber. This technology has been specially developed to solve one of the most commonly encountered issues in medical device design, where typically soft durometer materials tend to have high surface tackiness.

DUKE Empirical is your trusted designer and manufacturer of precision ePTFE medical products.
Advantages of ePTFE Covered Medical Devices & ePTFE Covered Stents
ePTFE is a strong material that is fibrulated in its microstructure which allows the material to be produced with varying porosity or density-based the manufacturing process used. As such, the material properties can be tuned to specific applications where the porosity is specified for example in filtration applications, or where the material is designed to provide a fluid seal such as in stent grafts where an aneurysm is excluded from the blood flow path. Due to ePTFE’s high strength and low friction, when used as a covering on implantable devices, it can withstand collapsing and expanding such as when an implant is compressed and loaded into a catheter system. ePTFE is widely used in vascular applications, particularly where there is a risk of clot formation such as in low flow arteries or arteries where the diameter is less than 4mm where knitted polyester grafts are prone to clotting and occlusion. Other properties that ePTFE provides includes:
- Variable permeability specific to application requirements
- Excellent high temperature stability
- Excellent chemical compatibility
- Can be produced as a filament and subsequently woven or knitted into a fabric structure
- Flexible,strong and thin, with low friction
ePTFE vs PET Stent & Medical Device Covering Materials
While other materials such as polyester (PET) are woven or knitted to produce thin and strong fabric structures, ePTFE is produced in the form of a non-woven film, thin or thick walled tube or as a filament and subsequently woven or knitted into a fabric structure. PET is more commonly used where fibrous tissue ingrowth is desired to provide long term stability and fixation to the implant as well as incorporating a durable seal between the device and native tissue. ePTFE can be combined with other materials with thermal bonding processes.
ePTFE Uniaxial or Biaxial Oriented Tubing
Through processing, ePTFE material can be made with anisotropic tensile modulus. These products are referred to as uniaxial or biaxial orientated film or tubing.
DUKE Empirical produces a wide range of ePTFE membrane materials and ePTFE products for unique device requirements such as self-expanding and balloon expandable stents and implantable devices.
