Abstract: A catheter for delivering a self-expanding stent-graft prosthesis includes an inner shaft component having a distal segment over which the stent-graft prosthesis is loaded in a compressed delivery configuration. The distal segment has a covering that is intimately disposed thereover. The covering forms a raised outer surface on the distal segment and includes a plurality of protrusions that extend radially outward from the raised outer surface. An outer shaft component is slidingly disposed over the distal segment of the inner shaft component for holding the stent-graft prosthesis in the compressed delivery configuration. In the compressed delivery configuration, the stent-graft prosthesis is disposed over and makes contact with the covering of the distal segment of the inner shaft component such that at least the plurality of protrusions provide sufficient friction to of the covering secure a longitudinal position of the stent-graft prosthesis relative to the inner shaft component.

Abstract: A method and device for treating a central vacuum system is provided for cleaning, deodorizing, disinfecting, adding fragrance and/or removing static electricity from the tubing network of the vacuum system. The treatment device is a cloth or other object that has been treated with a treating agent. The method includes the steps of placing the treatment device into an inlet of one of the tubes, and then actuating the vacuum of the central vacuum system so as to suck the device through the tube and into the vacuum so as to treat the tube as the object passes therethrough. One or more devices may be used for treating the network of tubes in the central vacuum system.
