Title: Endovascular delivery system
Inventor: WHITE GEOFFREY H
IPC: A61M39/06
Filed: 1997-08-27
Granted: 2008-12-23
Abstract: A system for delivering and implanting a radially expandable endoluminal prosthesis within a body lumen (e.g., blood vessel). The system comprises a) an introducer/dilator assembly, and b) a delivery catheter/loader assembly. The introducer/dilator assembly comprises an elongate tubular introducer sheath which may be provided with a valuing assembly mounted on the proximal end thereof. Such valving assembly may incorporate i) a hemostatic valve, ii) a first sealing valve and iii) a second sealing valve, positioned in series, to prevent leakage of body fluid out of the proximal end of the introducer and to permit two or more elongate members (e.g., catheters, guidewires) having differing outer diameters to be inserted through the introducer without leakage of body fluid therefrom. A dilator, which has regionalized differences in stiffness, is initially deployable within the lumen of the introducer to facilitate advancement of the introducer to its desired location within the body. Thereafter, the dilator may be removed from the introducer sheath and the delivery catheter/loader assembly may be attached to the introducer, such that the delivery catheter having the prosthesis mounted thereon may advanced through the introducer, to a desired location within the body. Thereafter, the radial expandable endoluminal prosthesis mounted on the delivery catheter is deployed and implanted by an expansion device (e.g., balloon) formed on the delivery catheter. The delivery catheter may incorporate one or more outflow apertures at specific location(s) to facilitate injection of radiographic contrast medium in a manner which will check for leakage around the endoluminal prosthesis, after the endoluminal prosthesis has been radially expanded and implanted.

Abstract: Electrical circuit elements such as electrically conductive strips are permanently applied to the surface of polyolefin parts, such as polyethylene parts which are manufactured by rotational molding, by use of a transfer which can be applied to the interior surface of a rotational mold at the start of the molding cycle or can be applied to the molded part after its formation.  The transfer comprises a carrier sheet on which the conductive circuit elements are printed with a mixture of wax or polyethylene powders containing from 30 to about 60 weight percent of conductive particles, preferably metal flakes. After application, the carrier sheet is removed and the conductive circuit elements are permanently incorporated into the surface of the polyethylene part by heating, either during the rotational molding cycle or by post-cycle heating of the formed part.

Abstract: The present invention relates to a system (10), method and terminal (14) for measuring the quality of service or QoS for services, for example, of the Internet type in which a telecommunications network (12) supports the delivery of the services by a server (16). The system (10) and the corresponding method allow to collect by means of the network (12, 18, 20) the QoS information, in particular information of insufficient QoS, to identify the causes of insufficient QoS and to discriminate in the attribution of said causes among the terminal (14), the server (16) or the network itself (12). The terminal (14) in addition to generating "objective" information about the QoS, such as the time for downloading a Web page, dimensions of the Web page and number of objects composing the page, is also able to generate "subjective" information, indicative of the actual QoS perceived by a user of the terminal (14).
