vascular prosthesis for the replacement or the inner lining of the blood vessels of the middle and large diameter and device for its implementation without interruption of blood flow

摘要

the present relates to a vascular prosthesis was found for the replacement or the inner lining of the blood vessels of the middle and large diameter, and a device for its implementation without theeast of blood flow.the vascular prosthesis includes a tubular body in a biocompatible material which includes, in the vicinity of its longitudinal ends.at least one annular body development is prepared basically coassialmente body and which is radially expandable tubular to the commitment of the section of the tubular body.it contains the body development is annular, against the inner walls of a blood vessel upstream of the section of the vessel to replace, or be internally, with the prosthesis.the body is formed by at least one annular development loop of at least one thread elasticamente flexible and is mounted in sliding way.on a support associated with a lateral portion of tubular body.this wire is smooth relative to the support to vary the size of the loop mentioned and provided contrast media of the flow of the wire relatively to the support for the maintenancethe expansion or contraction, with the loop through the flow controlled wire relatively to the support, at the end of the force that created them.
