    Abstract: A tubular stent formed from a plurality of cylindrical rings and connecting links where selected connecting links are of comparatively high mass in relation to the other links. The high-mass links have sufficient mass to be visible during a fluoroscopy procedure when formed from a moderately radiopaque material such as stainless steel. The high-mass links being arranged in a spiral pattern along the length of the stent to ensure that the stent is fluoroscopically visible regardless of the stents orientation during the implantation procedure.

    Abstract: An expandable stent for implantation in a body lumen, such as an artery, is disclosed. The stent consists 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 the longitudinal direction. The strength of the stent at a center section or at either end can be varied by increasing the mass of the struts forming each cylindrical element in that center section or end section relative to the lower mass struts in the remaining sections of the stent. Increasing the mass of the struts can be accomplished by, for a given strut thickness, increasing the width of the strut, or increasing the length of a cylindrical element.

    Abstract: A catheter assembly is provided for use in delivering and implanting a stent in a body lumen, such as in a coronary artery. An elongated catheter body includes an expandable member or balloon having a folded configuration and an expanded configuration wherein a plurality of pre-formed grooves extending generally circumferentially around the balloon when the balloon is in its folded configuration. An intravascular stent is removably crimped over the balloon and is at least partially retained on the balloon by the grooves. Upon inflation of the balloon, the grooves will flatten out thereby releasing the stent and allowing the stent to expand radially outwardly into contact with the body lumen or coronary artery.

    Abstract: The invention is directed to a stent that is relatively flexible along its longitudinal axis but can be crimped or reduced to a very low profile while maintaining the ability to expand radially outwardly to any number of diameters to support a body lumen such as a coronary artery. The stent includes a plurality of cylindrical rings connected to each other by links. The cylindrical rings have curved portions that are attached by arms having slits that, when expanded, form apertures or holes to permit the stent to be reduced to a very low profile for delivery purposes, yet be able to expand the stent to various diameters and to provide sufficient vessel wall coverage when implanted.

    Abstract: A strut pattern of an endoprosthesis includes a plurality of W-shape cells that define a tubular body, the W-shaped cells at the opposite ends of the tubular body have a modified configuration that is different than the W-shaped cells at the middle portion of the tubular body. At the distal end of the tubular body, the W-shaped cells have crests with axial positions that are axially spaced apart, and have troughs with circumferential positions that are spaced apart. At the intermediate and distal end of the tubular body, the W-shaped cells crests with axial positions that coincide and have troughs with circumferential positions that coincide. The strut pattern is cut from a tubular precursor construct made of PLLA that has been radially expanded and axially extended by blow molding.
