摘要:
A method of delivering a percutaneous heart valve is disclosed. The percutaneous heart valve includes an expandable frame having a plurality of cells and a valve seated inside the expandable frame. The heart valve also includes a proximal anchoring portion and a distal anchoring portion having a plurality of distal anchors. After expansion, the proximal anchoring portion extends distally and a portion of each distal anchor extends proximally. A portion of each distal anchor is positioned radially outwardly from the frame and extends in a direction that is substantially parallel with the longitudinal axis. Proximal portions of the distal anchors are preferably spaced apart by less than two cell lengths from a distal portion of the proximal anchoring portion. During deployment, radial expansion of the frame draws the proximal anchoring portion and the distal anchors into closer proximity with body tissue positioned therebetween.
