Abstract: Based on Laplace’s law and the mechanical characteristics of knitted vascular prostheses, mathematical models have been developed enabling one to determine the values of the relative circumferential elongation, circumferential forces and standard circumferential susceptibility of a prosthesis as a function of its diameter and internal pressure. The results obtained refer to the values of the parameters assessed for the initial phase of their exploitation, allow to preliminarily predict the values of these parameters.
