摘要:
A flow modifying apparatus may include a plurality of struts coupled together to form a radially expandable frame having a proximal end and a distal end. The proximal and distal ends may be radially expandable into expanded proximal and distal ends. A reduced diameter portion of the expandable frame may be disposed between the expanded proximal and distal ends and the reduced diameter portion may comprise a fluid flow through passage. A cover may be disposed over at least a portion of the radially expandable frame. The reduced diameter portion modifies fluid flow therethrough immediately upon implantation thereof and forms a pressure gradient between the inflow end and the reduced diameter portion.
