Percutaneous heart valve
First Claim
1. A method of deploying a percutaneous heart valve into a body cavity having an opening surrounded by surrounding body tissue, the method comprising:
- delivering a percutaneous heart valve to the body cavity in a collapsed configuration, the percutaneous heart valve comprising;
an expandable frame comprising a proximal end and a distal end and a longitudinal axis extending therethrough, the expandable frame comprising a plurality of cells configured to permit the frame to radially expand and collapse between the collapsed configuration and an expanded configuration;
a valve seated inside the expandable frame;
a proximal anchoring portion; and
a distal anchoring portion comprising a plurality of distal anchors; and
radially expanding the expandable frame to the expanded configuration within the opening, wherein, when the percutaneous heart valve is in the expanded configuration;
the proximal anchoring portion extends at least partially distally;
at least a portion of each distal anchor extends proximally to a proximalmost portion of the distal anchor positioned radially outward from the frame, the proximalmost portions extending in a direction that is more parallel with the longitudinal axis than with a transverse axis perpendicular to the longitudinal axis;
at least one of the plurality of distal anchors bends radially outwardly before bending to extend toward the proximal anchoring portion; and
the proximalmost portions of the plurality of distal anchors are spaced apart by less than two cell lengths from a distalmost portion of the proximal anchoring portion;
wherein radially expanding the expandable frame draws the proximal anchoring portion and the plurality of distal anchors closer together with the surrounding body tissue positioned between the proximal anchoring portion and the plurality of distal anchors.

Abstract
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.

12. A method of deploying a percutaneous heart valve within a body cavity having an opening surrounded by surrounding body tissue, the method comprising:
-
delivering a percutaneous heart valve to the body cavity in a collapsed configuration, the percutaneous heart valve comprising; an expandable frame comprising a proximal end and a distal end and a longitudinal axis extending therethrough, the expandable frame comprising a plurality of cells configured to permit the frame to radially expand and collapse for deployment within the opening of the body cavity between the collapsed configuration and an expanded configuration; a valve seated inside the expandable frame; a proximal anchoring portion; and a distal anchoring portion comprising a plurality of distal anchors, each distal anchor comprising an attached end connected to the frame, a free end, and a bend between the attached end and the free end; and radially expanding the expandable frame to the expanded configuration within the opening, wherein, when the percutaneous heart valve is in the expanded configuration; the proximal anchoring portion extends at least partially distally; at least a portion of each distal anchor extends proximally to a proximalmost portion of the distal anchor positioned radially outward from the frame, the proximalmost portions extending in a direction that is more parallel with the longitudinal axis than with a transverse axis perpendicular to the longitudinal axis; and the proximalmost portions of the distal anchors are spaced apart by less than two cell lengths from a distalmost portion of the proximal anchoring portion; wherein the radially expanding the expandable frame draws the proximal anchoring portion and the distal anchors closer together with the surrounding body tissue positioned between the proximal anchoring portion and the plurality of distal anchors. - View Dependent Claims (13, 14, 15, 16, 17, 18, 19)
