A stent assembly includes support rings each having interconnected circumferentially alternating inner prongs and outer prongs. The inner prongs define an inner diameter around a longitudinal axis. The outer prongs define an outer diameter greater than the inner diameter. A graft engages the support rings and follows a waving peripheral path. The graft may be a billowing graft. A second graft may surround the first graft such that tunnels are defined between the first graft and second graft. A method of making a stent assembly includes diametrically expanding the support rings onto a mandrel, engaging a graft with the support rings, and removing the support rings and graft from the mandrel permitting the stent assembly to contract to a neutral state.
A device and method for endovascular repair of a patient’s aorta is disclosed. The device includes a frame component that has a balloon-expandable frame and a self-expanding frame secured to the balloon-expandable frame. The device also includes a valve element positioned at the proximal end of the frame component. The device may include another prosthetic component that may be secured to the frame component. The prosthetic component may include at least one conduit configured to receive a covered stent.
A method of determining volume flow rate of a bodily fluid in a biological conduit includes determining a cross-sectional area of a biological conduit using a velocity vector map representing moving entities or moving fluid portions in a bodily fluid flowing within the biological conduit, calculating an average speed of the moving entities or moving fluid portions in the bodily fluid flowing across the determined cross-sectional area of the biological conduit, and calculating volume flow rate of the bodily fluid in the biological conduit from the determined cross-sectional area and the calculated instantaneous or average speed. A series of velocity vector maps may be collected over time so as to generate a flow rate profile representing flow rate as a function of time.
