ABSTRACT:
Vascular prosthesis for the substitution or internal lining of blood vessels of medium and large diameter and to a device for its application which includes a tubular body of biocompatible material that is associated with, at least at one longitudinal end, at least one body at annular development, that is disposed substantially coaxial to the tubular body and that is radially expandable for the engagement of the tract of the tubular body, which contains the body at annular development, against the inner walls of a blood vessel proximal to the segment of the vessel to be substituted, or internally lined, with the prosthesis. The body at annular development includes at least one loop of at least one wire elastically flexible, which is slideably mounted on a support associated to a lateral portion of the tubular body. This wire is slideable with respect to the support mentioned before to vary the amplitude of the loop and tools are predisposed to contrast the wire sliding in respect to the support in order to maintain the expansion or contraction, given to the loop by means of the controlled sliding of the wire relatively to the support, at ceasing of the force generating the sliding.
