TABLE 1.

Relevant parameters for the properties of vascular grafts.

Parameter	Definition	Test methods
Burst pressure	The pressure at which one end of the vascular graft is closed and liquid is slowly and uniformly injected from the other end until the vessel expands and ruptures	Bursting tester
Suture retention strength	Defined as the peak strength when the surgical wire is pulled out the wall of the tube	Universal tensile tester
Ultimate tensile strength	The maximum stress that the vascular graft can withstand when stretched before rupture	Universal tensile tester
Compliance	The ability of the vascular graft to expand radially due to internal pressure	Compliance tester
Patency	After vascular implantation, the grafts remained unobstructed without any intervention	Ultrasound
