A development of a technique for measuring the compliance of the textile vascular prostheses

The objective of this study is to develop a technique for measuring the compliance of the textile vascular prostheses without membrane. The principle of this test is to investigate the dimensional changes of prostheses, using imaging techniques, submitted to internal pressure. The internal compliance is broken into three categories: the radial compliance, the longitudinal compliance and the volumetric compliance. The results have shown a significant difference in compliance between the polyethylene terephthalate (PET) vascular grafts and the healthy host arteries.
