Aeos™ ePTFE is produced by mechanically expanding biocompatible PTFE to produce a microporous structure of solid nodes interconnected by fibrils. This versatile and flexible material can be customized in many different and complex geometries depending on the unique environment in which it needs to operate. Aeos™ ePTFE is available in three product groups: Aeos™ ePTFE Membranes and Ribbons; Aeos™ ePTFE Porous Tubing; and Aeos™ ePTFE Monofilament, Sutures, and High Strength Sutures.
The combination of a microporous structure coupled with the many PTFE properties that are retained after stretching, such as biocompatibility, ability to be sterilized, and flexibility, makes Aeos™ ePTFE an extremely versatile material that can be used in a diverse range of medical applications.
Aeos™ ePTFE membranes and ribbons excel in medical applications that demand porosity, flexibility, and strength. Membranes and ribbons are available sintered, or unsintered where further processing, such as lamination, is required. Ultra-thin, biaxially stretched membranes favor stent encapsulation, while thicker, uniaxially stretched calendared ribbons suit dental or cosmetic implants that are cut or formed into various shapes.
Aeos™ ePTFE porous tubing is perfect for applications that demand flexibility and robust performance. Alongside standard-sized tubing, ultra-thin ePTFE Sub-Lite-Wall™ uniaxially oriented tubing and ePTFE biaxially oriented tubing are both available. These products balance strength with flexibility, making them ideal for stent grafts or endoscope channels. The porous structure can promote new tissue in-growth for accelerated patient healing.
Aeos™ ePTFE suture products are designed to obtain better closure, minimize the immune response, and promote optimal tissue attachment for swift patient healing. Combining a 1:1 suture-to-needle ratio with a soft feel and excellent drape, lubricious Aeos™ ePTFE suture monofilaments (ASM) help minimize patient bleeding while ensuring accurate knot placement during delicate procedures. When a step up in strength is required, Aeos™ high strength suture monofilaments (AHSSM) retain the same characteristics as standard ASM but feature nearly three times the USP knot-pull strength, helping provide superior performance for long-term loading-bearing applications.
Stent Coverings – ultra-thin biaxially stretched membranes and porous tubing can be customized to suit individual stent designs and intended applications.
Implants – uniaxially stretched calendared ribbons are ideal for medical and dental implants that require thicker materials capable of being accurately formed or cut to shape.
Suturing – standard and high strength, flexible and adaptable sutures, or monofilament, tailored to your exact requirements.
Vascular Anastomosis – sutures can be swaged with a 1:1 needle-to-suture ratio for reduced bleeding, making it particularly effective for vascular anastomosis.
Tethering – high strength monofilament can be used to anchor or securely hold tissue and structures in place, such as in mitral valve repair or in certain dental procedures as a non-absorbable suture.
Vascular Devices – suitable for multiple vascular device applications, such as a porous encapsulation of metal scaffolds, or as a flexible distal tip liner in delivery devices.
Endoscopic Channels – can be used to reduce friction and kinking in biopsy channels, or as a liner for endoscopic channels in surgical robotics.
Medical Equipment – can be applied in many diverse medical equipment designs that require flexibility, porosity, and strength, such as insulation in RF ablation devices, or protection for optical fiber bundles in surgical lighting.
Vascular Closure Devices – high strength ePTFE sutures can provide advanced mechanical properties for applications requiring enhanced pull strength.
Biocompatible – a USP Class VI resin that is safe and trusted for use within the human body.
Brilliant White Color – improves visibility for surgeons.
Broad-spectrum Chemical Resistance – able to withstand and endure many chemicals without loss of integrity.
Broad Working Temperature – Aeos™ ePTFE has an extended working temperature up to 500 °F (260 °C).
Chemically Inert – this material is not chemically reactive with the tissue of the human body.
Customizable – uniaxial or biaxial stretching ensures the customer’s exact material and design requirements can be met in relation to density, porosity, pore size, and internodal distance.
Heat-sealable – important for laminating and encapsulation.
Hydrophobic – this material naturally repels water yet is still microporous to air, uniquely combining both properties together.
Light-passing Properties – can be used as a light guide in surgical suites, providing flexible protection to optical fibers that glow with illumination.
Low Dielectric Constant – an optimal choice for insulation applications.
Lubricious – the low surface friction of Aeos™ ePTFE allows surgeons to position knots with precision when used as a suture or monofilament.
Microporous – porous to air, this material is characterized by many PTFE nodes interconnected by fibrils, which allows it to be used in diverse applications where porosity is required.
Soft And Flexible – key properties for medical devices that need to safely traverse the vasculature of the body.
Super-thin – Zeus has a unique capability to produce super-thin ePTFE tubing with wall thicknesses as low as 0.002” (0.051 mm).
