    Abstract: An expandable stent is implanted in a body lumen, such as a coronary artery, peripheral artery, or other body lumen for treating an area of vulnerable plaque. The invention provides for a an intravascular stent having a plurality of cylindrical rings connected by undulating links. The stent has a high degree of flexibility in the longitudinal direction, yet has adequate vessel wall coverage and radial strength sufficient to hold open an artery or other body lumen. A central section is positioned between distal and proximal sections and is aligned with the area of vulnerable plaque to enhance growth of endothelial cells over the fibrous cap of the vulnerable plaque to reinforce the area and reduce the likelihood of rupture.

    Abstract: Stent designs for use in vessels, such as the carotid and coronary arteries, are disclosed. The stents consist of a plurality of radially expandable cylindrical elements generally aligned on a common longitudinal stent axis and interconnected by one or more interconnecting members placed so that the stent is flexible in a longitudinal direction. The cylindrical elements form a generally serpentine wave pattern transverse to the longitudinal axis between alternating valley portions and peak portions. The interconnecting members are attached to the double-curved portions to connect a cylindrical element to an adjacent cylindrical element and interconnecting members are attached to the inverted double-curved portions to connect the cylindrical element to the other adjacent cylindrical element. The stent designs include both a six crown and an eight crown stent which exhibit flexibility and sufficient radial strength to support the vessel.

    Abstract: A method of sterilizing a medical device component, such as a catheter balloon, in which an electron beam (i.e., e-beam) is applied to the component in an evacuated or inert gas-filled container. The method of the invention allows for electron beam sterilization without significant degradation of the component polymeric material. In one embodiment, the device component is configured to be pressurized or expanded during use. The method of the invention provides a component with a rupture pressure that is not significantly decreased due to electron beam sterilization. Another aspect of the invention is a medical device component, e-beam sterilized according to a method of the invention. A variety of medical device components can be sterilized by the method of the invention, and particularly intracorporeal devices for therapeutic or diagnostic purposes, such as balloon catheters, catheter shafts and balloons, stent covers, and vascular grafts.

    Abstract: A catheter having an elongated shaft which has a multilayered distal tip with a first layer formed of a polyimide first material and a second layer formed of a polymeric second material. In one embodiment the multilayered distal tip is a separate member, distal to the distal end of a proximal portion of the shaft. In another embodiment, the shaft has an outer tubular member, and a multilayered inner tubular member with a distal end which forms the multilayered distal tip of the shaft. In a presently preferred embodiment, the polyimide material is a thermoset polyimide. In one embodiment, the polymeric second material is a polyamide material.
