Approach

An ideal vascular graft has the appropriate size to match the host blood vessels, allows for rapid healing, ease of handling, exhibits increased porosity, resistance to infection, low thrombogenity and is low cost.

The Visi4 approach is unique. Thrombosis-resistant hydrogels are impregnated into a bulk silicone vascular graft material. The resulting interpenetrating polymer network (IPN) integrates hemocompatible properties into the silicone bulk material. The result is highly beneficial mechanical and hemocompatible properties in one flexible material which does not decompose in vivo.

In this way we leverage the blood vessel's natural design and function to redefine how cardiovascular diseases should be treated with vascular grafts.
