    Abstract: An expandable hybrid stent having metallic rings and polymer interconnecting links is disclosed. One embodiment of the stent has radially expandable cylindrical rings generally aligned on a common axis and interconnected by one or more polymer links that attach at formations formed in the rings. The polymer links have sufficient column strength to keep the rings from collapsing together axially. The formations may be holes, notches, grooves, channels, dovetails, or the like and the links wrap around, pass through, or lie on the formations. The junction of the link and ring at the formation is then melted and allowed to solidify. Alternatively, beads may be formed on either side of where the link passes through a hole in the ring thus securing the ring to the link.

    Abstract: The invention is directed to an expandable stent for implantation in a body lumen, such as a coronary artery. The stent consists of radially expandable cylindrical rings generally aligned on a common axis and interconnected by one or more links. At least some of the links are formed of a polymer material providing longitudinal and flexural flexibility to the stent while maintaining sufficient column strength to space the rings along the longitudinal axis.

    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.

    Abstract: A blow molding apparatus for expanding a polymer tube and a method for fabricating a stent using the apparatus is disclosed. The polymer tube is disposed within a tubular mold, over which a heated ring is made of a material having thermal conductivity greater than the tubular mold is translated. The ring is heated with heated fluid streams applied directly onto an outer surface of the ring, or heated fluid circulated within the ring, or an electrically resistive coil within the ring, or combinations thereof. The heated ring uniformly heats a circumference of the tubular mold that, in turn, uniformly heats a circumferential band of the polymer tube. The heated polymer tube is progressively expanded radially and axially while the ring is translated longitudinally over the polymer tube. The expanded polymer tube can be heat set and cooled prior to removal from the tubular mold.
