The Advanta VXT

VXT vascular graft is a synthetic vascular prosthesis made of expanded Polytetrafluroethylene(ePTFE).

 It is comprised of a reinforced two layer design to offer greater strength compare to those  single layer ePTFE grafts.

Construction – Structure Dictates Function

Advanta VXT is designed to be the strongest PTFE graft on the market today. The base material is a hybrid wall architecture, which means the product is strong. Atrium has added its new “soft-wrap technology” to create a product that is stronger and designed to heal better than other wrapped products. Advanta VXT is designed for those that want or need a wrapped product.

 VXT grafts are also offered with or without helical support ( commonly referred as Rings) should additional radial support be preferred. Additionally , grafts can be ordered as standard wall thickness or thin wall thickness:

Ring(Helix)

Advanta VXT grafts are also offered with a helical coil (made of ePTFE) that is wrapped around the outer surface of the graft. This helix provides additional radial support to minimize graft compression. Common uses for a helix wrapped graft would be when graft placement falls across a joint, where unwanted compression of the graft is likely to occur . Unlike competing products , our helix can be peeled off(by following the procedure in tthe IFU) so that it will only be present where desired.

Radial Tensile Strength

In addition to significant suture retention strength, the wrap adds considerable radial tensile strength. Radial Tensile Test is a measure of the force required to stretch or extend the graft in a radial direct. This test mimics the stress and force that a graft may be put through as it is manipulated.
