Abstract
The present invention relates to a braided corrugated vascular prosthesis with a textile structure consisting of at least two types of biocompatible fibres, of which one is absorbable by the human body, and to the process of producing same using conventional braiding equipment, by combining previously braided biocompatible threads so as to form strings, on a mandrel (4) and a spiral (3), to ensure the necessary diameter and corrugation. The braided vascular prosthesis is homogeneously impregnated with a substance that promotes sealing. The corrugated structure confers to said prosthesis the necessary elasticity for use in blood vessels. The thus produced prosthesis re-establishes blood flow in damaged segments of a blood vessel, and is particularly useful in vascular surgery. ç
