    摘要: A hybrid stent is formed which exhibits both high flexibility and high radial strength. The expandable hybrid stent for implantation in a body lumen, such as a coronary artery, consists of radially expandable cylindrical rings generally aligned on a common longitudinal axis and interconnected by one or more links. In one embodiment, a dip-coated covered stent is formed by encapsulating cylindrical rings within a polymer material. In other embodiments, at least some of the rings and links are formed of a polymer material which provides longitudinal and flexural flexibility to the stent. These polymer rings and links are alternated with metallic rings and links in various configurations to attain sufficient column strength along with the requisite flexibility in holding open the target site within the body lumen. Alternatively, a laminated, linkless hybrid stent is formed by encapsulating cylindrical rings within a polymer tube.

    摘要: A wireless voice over Internet Protocol (VOIP) system comprises a VOIP-enabled wireless communication device (WCD) and a VOIP gateway. The WCD includes a short-range wireless interface and a client application configured to place and receive VOIP calls through the short-range wireless interface. The VOIP gateway includes a short-range wireless interface for communicating with the WCD, a network interface for communicating with the Internet, and a VOIP service client configured to communicate with a VOIP service over the Internet by way of the network interface. The VOIP gateway also includes a proxy server configured to act as an interface between the WCD client application and the VOIP service client and to route the VOIP calls through the gateway's short-range wireless interface.

    摘要: An improved stent system for treating a bifurcation. Up to three stents are mounted on two parallel balloon catheters wherein a proximal stent is disposed about both balloons while two distal stents are each disposed about one of the balloons. Such configuration enhances the flexibility of the assembly to facilitate its advancement through tortuous vasculature, while the structural independence of the stents maximizes the systems ability to spread into a wide range of bifurcation angles. A single link between each distal stent and the proximal stent may be relied upon to maintain relative stent position during deployment.

    摘要: A method of coating a stent may comprise applying a composition including a drug and a polymer to the stent to form a coating. The release rate of the drug from the coating gradually increases along a length of the stent which extends axially from opposite ends of the stent. The variable drug release rate can be accomplished by varying the coating thickness, by applying a barrier region over the drug-containing composition, and/or by having different polymers in the coating, the polymers having different drug permeabilities.
