The FlowWeave BIOSEAL vascular grafts are manufactured using the most modern weaving technique and feature high burst strength and low dilatation. The use of a specially texturized yarn supports superior tissue incorporation and healing characteristics. Because of the aldehyde- and isocyanate-free BIOSEAL impregnation, the grafts are primarily blood-tight and are characterized by extraordinarily soft and pliable handling. The concentric crimping and a guideline enable for safe and exact positioning at the surgical site. The FlowWeave BIOSEAL vascular grafts are available as straight tubes in diameters of 10 to 38 mm and in lengths of 15 to 60 cm.
