Structure of Elastic Woven Vascular Implants

Vascular implants are used to replace the abnormal segments of the cardiovascular system. Such operations are necessary to restore a normal blood flow. Scientists propose the arterial prosthesis and the aortic prosthesis of various innovative structures and designs. The implants have been manufactured by weaving and then impregnated with a solution of biologically active agents. Polyester yarns and polyurethane yarns have been used for the manufacturing of implants. These implants have very good deformation properties in the longitudinal and radial directions. Zero water permeability is achieved by means of a special impregnation. The structure of the wall of the prosthesis can be incorporated into a living organism without complications. These prostheses provide normal hemodynamics for a long time
