Relay® Plus is a dacron endoprosthesis and nitinol stents, indicated for the treatment of thoracic aortic aneurysm. The nitinol stents have a “Z” shape and are found along the length of the prosthesis covered by the Dacron fabric, except at the most proximal end not covered, facilitating the positioning of the prosthesis on the aortic wall. Also, it has an S-bar giving it columnar strength and to facilitate its visualisation and correct orientation it has radiopaque markers.
The release system has two sheaths, an external hydrophilic one to facilitate access to the aorta and another internal one for the approach of the aortic arch with a “D” shaped radiopaque marker.
The endoprosthesis is available in two configurations: straight and tapered.
