After an introductory study of vascular prostheses pointing out a classification of these devices and the various types of materials used for their construction, the fundamental parameters for in vitro characterization of vascular prostheses, as defined in the European and international references standards, are reported. Compliance of prosthetic vessels is an important physic parameter affecting long-term performance of prostheses. From the definition of the compliance of these devices, the instrumentation used to calculate this parameter is presented and the software data acquisition and elaboration realized at the Laboratory of Biomedical Engineering is described. This software permits the characterization of the static and dynamic compliance in a physiological frequency range.
