Document Type and Number:
Japanese Patent JP2011515191
Kind Code:
A
Abstract:
A generally tubular, cylindrical stent prosthesis has an unexpanded delivery configuration and an expanded configuration for contacting the vessel wall. The stent prosthesis has a plurality of adjacent stent struts, each stent strut having a wavelike or sinusoidal pattern of straight segments and crowns. A Y-shaped member is attached to one or more crowns to cause the crowns to flare outwardly at an angle from the cylindrical stent body when the stent is expanded. Upon expansion of the stent, the crown(s) having Y-shaped members attached thereto are angled with respect to the longitudinal axis and radially flare from the cylindrical stent body. The flared crowns anchor the stent within the vessel by protruding into the vessel wall and/or seating the stent within an ostium.
